2 Introduction

Thank you for purchasing the Electro-Voice Dx46 Digital Signal Processor. The Dx46 Digital System Processor is a universal two-input, six-output digital signal processor with the flexibility of configuration to handle a multitude of audio system needs and applications; installed sound, house of worship, convention & meeting facilities, concert touring, club, portable sound reinforcement and more.

CAUTION: To achieve optimum performance and guard against damage to the processor, your sound system or yourself, please read, understand and follow all of the directions contained in this Owner's Manual. Failure to do so may result in improper performance, loss or injury.

2.1 Dx46 Features

The internal signal processing structure can be configured as 2-way stereo + full-range, 3-way stereo, 4-way mono + full-range, 5-way mono + full range, 3-way stereo with a mono sub + full-range, 4-way stereo with mono sub and low frequency and finally as a freely assignable 2 × 6 matrix router.

The Dx46 replaces entire racks of signal processors previously needed to properly configure and control sound reinforcement systems with a single Dual-Core DSP processor. The substantial advantages of the Dx46 over discrete signal processing racks include:

24-bit, 48 kHz digital signal path
No patch cables to fail or add noise
- Optimal gain structure throughout all stages of signal processing; no gain matching from processor to processor.
- Recallable factory and user presets; instant system reconfiguration for differing applications and performances.
- Easy, intuitive operation and editing with a PC and IRIS-Net

FIR-DRIVE

The Dx46 includes Finite Impulse Response (FIR) filters at each output for loudspeaker linearization. Using FIR filters has the following advantages, compared to using IIR filters (e.g. Bessel, Butterworth,...):

extremely linear frequency response
- very high stop-band attenuation
- linear phase systems

To sum up, FIR-DRIVE allows the linearization of frequency and phase of your Electro-Voice loudspeakers. Activating FIR-DRIVE is as easy as loading a FIR Speaker Setting in the output channel of the Dx46. The IRIS-Net software is used for loading Speaker Settings, and lots of Electro-Voice FIR Speaker Settings are included. Please refer to the documentation of IRIS-Net for more details about using Speaker Settings.

2.2 Unpacking & Warranty

Carefully remove the Dx46 from its packaging and packaging materials. Please save all packing materials and box, should you ever need to return the Dx46 for warranty service. Included with the Dx46 is this Owner's Manual, Warranty card and A.C. power cable. Contact your distributor, dealer or installer if any of these items is not included. Please save the warranty certificate and receipt; which must be presented at the time of warranty service for the factory warranty to be valid.

2.3 IRIS-Net

The IRIS-Net (Intelligent Remote & Integrated Supervision) PC software is used to configure and operate the Dx46. The configuration of the Dx46 can be done offline (i.e. without connection between the PC and the Dx46) on the PC. After the connection between the PC and the Dx46 has been established via Ethernet or USB, the configuration can be transmitted to it. In addition to configurations, IRIS-Net can also be used for extensive supervision, control and monitoring of the Dx46. The latest version of IRIS-Net is available at www.electro-voice.com.

2.4 Quick Start

CONNECT Dx46

Connect the signal inputs and outputs of the Dx46 (console - Dx46 - amplifier). You must make sure that each output is connected to the correct amplifier and loudspeaker(s). The Dx46 must be connected to A.C. power only by means of the provided IEC A.C. cable or by a power cable provided by the dealer / installer to match the configuration of your country or region. After power-up the number and name of the last loaded preset and the configuration mode is indicated.

RECALL PRESET

Press the Recall button and select the factory preset matching to your speaker configuration. Press the Recall button again to activate the preset. If the configuration of the Dx46 changes the Recall button has to be pressed a third time. The configuration LEDs indicate the function of each output channel. Full range is indicated by no lit LEDs.

Illustration 2-1: Output assignment LEDs

CAUTION: The parameter settings of the Dx46 factory presets are highly optimized and should not be changed. Especially editing the X-Over, PEQ or Limiter settings can result in damaged speakers.

The following steps are shown for one output channel only.

CONFIGURE LEVEL

Press the Level button to open the Level/Amp dialog.

OUT 1:Level/Limiter Level: 6.0dB Polarity:Inv Amp:User Gain:39dB 

The Level parameter allows adjustment of the level ratio between sub and top speakers. E.g. if the parameters in a preset are optimized for 2 subs you can increase the sub level by 6 dB if you are using 1 sub in your application. As an alternative you can decrease the top level by 6 dB.

SELECT AMPLIFIER TYPE

Select the power amp type connected to the Dx46 using the parameter Amp. Please note there are multiple entries for an amplifier type if the amplifier allows different sensitivity settings.

OUT 1:Level/Limiter Level: 6.0dB Polarity:Inv Amp:TG-7 (O dBu) 

If the amplifier type connected to the Dx46 is not included in the list, select the entry User. In this case you have to adjust the parameter Gain manually. Check the technical specification of your amplifier for the gain value.

OUT 1:Level/Limiter Level:6.0dB Polarity:Inv Amp:User Gain:39dB 

If the correct gain value is unknown set the parameter Amp to Default. For this setting a gain of 39dB is used, this is sufficient for most amplifiers. By selecting the right amplifier type the limiter settings of the channel are adapted automatically, so the connected speakers are protected as required.

Ensure the level of the amplifier is set to 0dB to get the maximum power from the amps.

CONFIGURE DELAY

The Dx46 can be used to compensate for the positioning of cabinets or speaker arrays relative to each other or the original sound source.

Press the SPEAKER Delay button for adjusting one or more output channels and select Active in this dialog.

Select the preferred Unit (using cm as unit is recommended) and edit the setting of the parameter Delay.

OUT 1:Output Delay Active  
Delay: 7.0  
Unit: ms 

Setting the correct Delay value is important to avoid acoustic cancellation of signals. E.g. when using the two full-range channels of the configuration "2way + FR" as delay lines, the Delay of this two channels has to be adjusted according to the distance to the main PA.

If all connected speakers are used as a delay line, or the main PA should be moved acoustically "back to the stage", the input delay parameter of input channels A and/or B should be used in this cases. Press the USER Delay button to use the input delay, up to 2 seconds of delay are available for each input.

CONFIGURE EQUALIZER

Use the GEO (31 band) and PEQ (10 band) of each input channel for adjusting the sound of your system to your room characteristics. Press the USER PEQ or GEO button to open the equalizer dialogs.

IN A:PEQ1 Active  
Type: Hipass F: 20000.0Hz  
Slope: 12dB/0ct Q: 2.0 

IN A:GEQ Detail  
F:20Hz Gain:0.0dB Active  
Type: Symmetric Q Q: 4.3 

3 Controls & Connection

3.1 Front Panel

USB 1.1 port for connection to a PC running Windows XP, Vista or 7. With a connected PC you may run the IRIS-Net Application. The Dx46 can be operated, edited and configured with an easy to use, intuitive interface. Any available firmware updates downloadable from www.electro-voice.com can be loaded via the USB port as well; allowing for easy updates.

1 - USB CONNECTOR

2 - INPUT LEVEL METERS

The Dx46 does not itself have input level controls. Proper input level adjustment is accomplished by setting the output level from the (L / R) bus outputs from the connected mixer (or other audio output device), as the vast majority of today's mixer-outputs are dBu calibrated. When the mixer is operating at optimal levels, so is the Dx46. The input meters monitor the input level of either analog or AES-EBU inputs, depending on the input mode selection set in the Setup Menu. Optimal signal-to-noise performance is obtained when the nominal (average), input level consistently lights the +6dBu (green) and +12dBu (Yellow) LED indicators. As the Dx46 is a digital audio device – and digital clipping produces very unpleasant results, the Clip (red) LED should not light. If the Dx46's input does clip, reduce the output level of the connected mixer. The -6dB PAD can be used for adjusting the input level also.

3 - LCD DISPLAY

The back-lit, 192 × 32 graphic LCD display allows for operation and editing of the Dx46 without the need for an attached PC. The contrast can be set in the Setup Menu for varying lighting conditions and viewing angles. The LCD display works in conjunction with Menu buttons, < SELECT > buttons and VALUE up/down buttons - to operate, navigate and edit the Dx46's parameters. In Run mode, the LCD displays the number and name of the currently selected factory or user preset. Pressing the Recall or Store buttons switches to their respective menus. Pressing the Edit or Setup menu buttons switches the display to the last edited parameter.

In Edit and Setup mode, the top line of the LCD display shows the currently selected parameter edit screen. Use the < SELECT > buttons to activate the top line of the display, and the VALUE up/down buttons to scroll through available parameter edit screens.

4/5 - VALUE UP/DOWN BUTTONS

Depending on the current LCD screen, the VALUE up/down buttons performs the following function:

• Recall - Select forwards/backwards through the stored preset list to select a preset to be recalled to current memory.

• Store - Select User Preset destinations forwards/backwards to select a destination for the currently edited preset, scroll forwards through ANSI character set to name preset.
  Edit / Setup - Scroll forwards/backwards through Edit / Setup screens when the top line of the LCD screen is active. Scroll forwards through values for the selected parameter in an Edit / Setup screen.

6 - EDIT / COMPAREBUZZONS

Pressing the Edit button while in Run mode places the current preset in Edit mode and the Edit button lights. The LCD display shows the last edit screen that was selected. From this point, any edit screen can be displayed and altered. Pressing the Edit button again "compares" the edited preset, if parameters have been altered, to the original un-edited preset. This compare function will audibly switch between the altered parameters and the previously stored settings, allowing you to hear the effect of any DSP changes that have been made. Use this feature to monitor progress in editing or creating presets. Subsequently recalling a new preset will prompt you to save changes, which you may do or not.

7 - SETUP BUTTON

Pressing the Setup button while in Run mode displays the Setup menus in the LCD display and the Setup button lights. In this mode, any Setup menu can be displayed and altered. Changes made to Setup menu items are saved automatically. To exit Setup mode, press the Setup button again. The LCD display will revert to Run mode.

8 - SELECT < BUTTON

The SELECT < button is pressed to navigate backwards through Edit, Setup and / or Recall menu displayed. The button cycles through all available value fields in a screen and wraps around from first to last.

9 - SELECT > BUTTON

The SELECT > button is pressed to navigate forwards through Edit, Setup and / or Recall menu displayed. The button cycles through all available value fields in a screen and wraps around from last to first.

10 - STORE BUTTON

Pressing the Store button while in Run mode displays the Store Preset screen in the LCD display and the Store button lights. In this screen edited presets can be named and saved to a user preset location. Pressing the Store button again completes the preset save operation. To exit without storing the current preset, press the Edit or Setup buttons to return to the Run mode screen.

11 - RECALL BUTTON

Pressing the Recall button while in Run mode displays the Recall Preset screen in the LCD display and the Recall button lights. In this screen, any of the 60 factory and 30 user presets can be recalled into current memory. Pressing the Recall button again completes the preset load operation and returns the LCD display to Run mode. To exit without storing the current preset, press the Edit or Setup buttons to return to the Run mode screen.

12 - USER PEQ BUTTON

Pressing the USER PEQ button places the current preset in Edit mode and jumps to the first screen of the parametric User Equalizer. Subsequent button presses toggle the display between Input A and Input B.

13 - USER GEO BUTTON

Pressing the USER GEO button places the current preset in Edit mode and jumps to the first screen of the graphic User Equalizer. Subsequent button presses toggle the display between Input A and Input B.

14 - USER DELAY BUTTON

Pressing the USER Delay button places the current preset in Edit mode and jumps to the User Delay screen. Subsequent button presses toggle the display between Input A and Input B.

Pressing the SPEAKER X-Over button places the current preset in Edit mode and jumps to the first Output Channel Cross-Over screen. Subsequent button presses step through the available output channels (depending on configuration).

Pressing the Delay button places the current preset in Edit mode and jumps to the SPEAKER Delay screen. Subsequent button presses step through the available output channels (depending on configuration).

Pressing the Level button places the current preset in Edit mode and jumps to the SPEAKER Level screen. Subsequent button presses step through the available output channels (depending on configuration).

Press and hold the SPEAKER Level button for 4 seconds to open the Limiter screen. Subsequent button presses step through the available output channels (depending on configuration).

20 - OUTPUT LEVEL METERS

Each output channel has an eight-segment output level VU meter. Meter response characteristics can be selected in the Setup menu:

Normal Fast,
Peak-Hold,
Slow Decay.

The yellow segment indicates that there is no headroom left to the selected VU reference i.E. D/A Converter Clip or Limiter Threshold. The red segments indicate clipping within the output signal path and should be avoided by adjusting the Output Level of the output channel. It is important to understand how the meters work and what they are displaying. The Output Meters are displayed as "dB to Limiter Threshold" or "dB to D/A clip". In other words, these meters will display the headroom between the output level and the limiter threshold or clip threshold of the D/A converter. When viewed in conjunction with the Gain Reduction meters, this provides a complete display of level and headroom before and after limiting has been engaged to allow system levels to be optimized. This also means that the output metering will be displayed differently depending on the limiter threshold setting.

21 - OUTPUT GAIN REDUCTION METERS

Each output channel has a four-segment gain reduction meter that shows the effect of the output channel Limiter on output signal; from -3dB to -12dB.

22 - OUTPUT CHANNEL MUTE BUTTONS

Each output channel has a lighted Mute button. Pressing the Mute button turns off the output of that channel. The button lights red as an alert. Press the Mute button again to restore the output channel's signal. Output channels may also be muted from IRIS-Net Application, if the unit is connected to a PC. Muting a channel in any window of the application will light the channel Mute button on the front panel of the unit as well.

23 - OUTPUT CHANNEL FUNCTION INDICATORS

Each output channel has a four-segment function display for informational purposes only. For any given configuration possible with the Dx46, an output channel may be identified as a sub, low, low/mid, mid, mid/hi, hi or full range output. One or two adjacent LED are displayed to indicate all possible output bandpasses. (Full range is indicated by no lit LED's.)

3.2 Rear Panel

24 - A.C. INLET

The Dx46 features a standard IEC A.C. inlet that will accept universal power cords. The Dx46 power supply is autoranging and can accept voltages from 100 to 240V AC, 50 to 60Hz . Only A.C. cords approved for use in your country should be connected to the Dx46.

25 - A.C. Fuse

The A.C. inlet includes a fuse holder that contains the mains fuse as well as a spare fuse. If necessary, replace the fuse only with a specified 5x20mm, T800 mA, L250 V replacement. Disconnect A.C. power before replacing a fuse. Before turning the unit back on, assess the condition of the A.C. receptacle powering the Dx46. If fuses continue to blow, refer servicing of the Dx46 only to qualified service personnel.

26 - A.C. POWER SWITCH

The A.C. power switch turns power to the Dx46 On and Off.

27 - CONTROL PORT

The CONTROL PORT of the Dx46 provides five control inputs and a reference connection for ground. The control inputs can be used for the recall of presets.

28 - ETHERNET INTERFACE

A computer and/or other ethernet devices (e.g. Dx46, NetMax N8000) can be connected via the Ethernet interface for 100Base-TX / 10Base-T Ethernet networks. Normally this connection is established via a standard (straight through) Ethernet cable and an Ethernet hub or a switch. The Dx46 can be connected directly with a computer or another Dx46 using a standard or crossover Ethernet cable.

29 - BALANCED XLR OUTPUTS

Each output channel has an electronically balanced XLR connector for connection to system amplifiers. Each output channel can output different frequency ranges depending on its assignment and cross-over settings.

CAUTION: Care must be taken to assure that each output is connected to an appropriate amplifier and loudspeaker to avoid damage or unexpected results. Note that a new preset may change the assignment of channel and its frequency range. For instance an output assigned to Hi frequency speakers in one preset, may be assigned as a sub output in another. See "Configurations of the Dx46".

30 - AES/EBU THRU PORT

The AES/EBU THRU port allows looping-through the digital audio signal to other devices. The digital input signal gets internally buffered and preprocessed (level matching / slew rate) before it is output via the THRU connector. This allows fairly simple wiring between devices, without the need for AES/EBU distribution amps as they are usually used. The Dx46 has a bypass-relay, which, in case of damage (e.g. power outage), connects the AES/EBU INPUT signal directly to AES/EBU THRU. This ensures trouble-free operation of downstream devices.

31 - AES/EBU INPUT

In addition to the analog audio inputs, an AES/EBU digital stereo input is provided and selectable in the Setup menu. The input conforms to IEC standard 60958 Type I. Connections must be made with three conductor, 110-Ohm, twisted pair cabling and an XLR connector. Digital audio signals in AES3 format with a sample rate from 32 kHz to 192 kHz can be connected. Please note that the maximum cable length depends on the sample rate.

32 - LOCK LED

The LOCK LED lights green as soon as the AES/EBU input has been synchronized to the incoming signal and thus proper audio transmission has been established. The LOCK LED is dimmed with no digital audio signal being present at the input or the internal PLL not having locked on to the incoming signal.

33 - BALANCED XLR THRU

Each analog audio input is connected to an electronically buffered and balanced output as a through connector. The signal does not run through any digital conversion or processing. These connectors are used to pass input audio to a second Dx46 used as a slave or to other audio inputs in the system.

34 - BALANCED XLR INPUT

Each input has an electronically balanced, locking XLR connector. In stereo or dual modes, connections to both inputs must be made. In mono modes, only one connection need be made, typically to Input A.

35 - 6dB LED

Input levels to the Dx46 can be reduced 6dB prior to the A/D converter to compensate for higher-level output from mixers and other audio devices. For ideal signal to noise performance when connecting the Dx46 to high output level devices engage the 6dB pad rather than turning down the output of the connected device. The Dx46's Input level Meters (2) will indicate incoming signal level and whether attenuation is required. This LED is permanently yellow when the 6dB pad is activated.

3.3 Installation

For proper operation, all directions regarding installation and connection must be followed.

MOUNTING

The Dx46 should be mounted in a rack-mount enclosure or rack rails. The unit is 1RU tall by 14" (353mm) deep. Proper clearance for air circulation around the unit must be provided. Do not block any vent holes on the unit. All four mounting points provided by the rack ears must be secured.

POWER CONNECTION

The Dx46 must be connected to A.C. power only by means of the provided IEC A.C. cable or by a power cable provided by the dealer / installer to match the configuration of your country or region. The Dx46 must only be connected to a properly wired, three pin, grounded A.C. outlet. A.C. power must range from 100 to 240 V AC, 50 to 60Hz. The Dx46 internal power supply is an auto-ranging design; no adjustments are necessary to configure it for proper A.C. power.

AUDIO CABLES (ANALOG)

Always use correctly shielded audio cables when connecting to the Dx46.

Balanced Input / Output Connections

To minimize induced noise caused by audio cables and to maximize the length of cables used, balanced connections are strongly advised for both Inputs and Outputs.

The XLR jacks provided on the Dx46 are configured as pin 1 ground, pin 2 hot (+), pin 3 cold (-). Cable shielding must be connected to pin 1. XLR - XLR cables or 14 "tip-ring-sleeve - XLR cables can both be used for balanced connections to the Dx46.

Un-balanced Input / Output Connections

Un-balanced connections can be made to the Dx46, although induced noise from cabling may be increased. Cables should also be less than 15^ (5 m) in length. Unbalanced connections can be 6dB lower in level as well. To match the audio level obtained with a balanced connection, it is necessary to tie pin 3 to ground at the XLR connector. This may increase noise.

AUDIO CABLE (AES/EBU)

A digital AES/EBU input (AES3) is provided in addition to the analog input. The digital input signal has to be connected to the AES/EBU INPUT connector. The AES/EBU input is a balanced transformer-isolated input. A sampling rate converter translates the input signal to match the internal sampling rate. The XLR jacks provided on the Dx46 are configured as pin 1 ground, pin 2 hot (+), pin 3 cold (-). Cable shielding must be connected to pin 1. XLR - XLR cables or 14 "tip-ring-sleeve - XLR cables can both be used for balanced connections to the Dx46.

HINT: Connections must be made with three conductor, 110-Ohm, twisted pair cabling.

ETHERNET

By connecting the Dx46 via the Ethernet interface, communication between the Dx46 and one or several PCs is possible. This allows the configuration of Dx46 via IRIS-Net software. The Ethernet interface on the rear of Dx46 is a RJ-45 connector (8P8C). Both 10Base-T and 100Base-TX Ethernet standards are supported.

Status LEDs

The status of the Ethernet interface is indicated by a orange and a green LED. If the Ethernet interface is not used both LEDs are off. The orange Link LED a the left side of the Ethernet interface lights, when the Dx46 has established a Ethernet connection to another device, e.g. another Dx46 or an Ethernet switch. The green network traffic LED at the right side of the Ethernet interface lights when sending or receiving a data packet.

CONTROL PORT

The CONTROL PORT of the Dx46 provides five control inputs and a reference connection for ground. The control inputs can be activated using external switches, pushbuttons or relays to connect them to ground potential, see following example.

USB PORT

Connecting the Dx46 to a PC for operation via IRIS-Net application can also be accomplished via the front panel USB port. The port conforms to the USB 1.1 Type B specification. Type B USB cables are readily available at computer dealers. According to USB specifications, the cable which is connected to this interface must not be longer than 15^ (5 meters). The USB interface of the Dx46 is a USB B (female) connector.

CONNECTION TO AMPLIFIERS

It is very important to confirm correct connection to all amplifiers. The Dx46 has the ability to configure each output for a specific frequency range; sub, low freq, mid freq, high freq. You must make sure that each output is connected to the correct amplifier and loudspeaker(s). Incorrect connections could lead to unexpected results or damage to loudspeaker components. Note also that each preset in the Dx46 includes DSP and bandpass parameters for the output channels. It is possible for a new preset to change an output from Hi to Sub, for instance. Make sure that connections to amplifiers and loudspeakers are correct before using a new preset.

INPUT LEVEL ADJUSTMENT

The final step in setting up, installing and connecting the Dx46 is to set proper input levels to the unit. The Dx46 does not itself have input level controls. Proper input level setting is accomplished by setting the output level from the (L / R) bus outputs from the connected mixer (or other audio output device). The input meters monitor the input level of either analog or AES/EBU inputs, depending on the input mode selection set in the Setup Menu. Optimal signal-to-noise performance is obtained when the nominal (average), input level consistently lights the +6dBu (green) and +12dBu (Yellow) LED indicators. As the Dx46 is a digital audio device – and digital clipping produces very unpleasant results – the Clip (red) LED should never light. If it does, reduce the output level of the connected mixer.

Input levels to the Dx46 can be reduced 6dB to compensate for higher-level output from mixers and other audio devices. For ideal signal to noise performance when connecting the Dx46 to high output level devices, engage the 6dB PAD rather than turning down the output of the connected device.

Select „Master“, if this Dx46 should write the parameter settings to one or more other Dx46 (Slave). Select „Slave“, if the parameter settings of this Dx46 should be read from another Dx46 (master). Select „off“, if the parameter settings of this Dx46 should be independent from other devices.
Id	0	Each master Dx46 connected to the ethernet must have an unique network id. Enter the id of the Master Dx46 the parameters should be read from if this Dx46 is used as „Slave".
Mask	all groups selected	If the Link „Slave“ is selected, choose the parameter groups that this Dx46 should read from the Master Dx46. Following groups are available: • D: Parameters of the device • A or B: Parameters of input A or B • 1 to 6: Parameters of output 1 to 6

PARAMETER UNITS

This window allows selecting the unit used for temperature and the limiter threshold. Additionally the air temperature can be entered.

Setup: PARAMETER UNITS Temp: 68.0^ Units: Fahrenheit Limiter Threshold: dBu (DSP output)

The parameter Temp is used to calculate the speed of sound for converting delay times into distance. Use the < SELECT > buttons to navigate to the Temp and Units parameters. Use the VALUE up/down buttons to choose between -4.0 °F to +140.0 °F or -20 °C to +60 °C. The Units parameter lets the user choose between Fahrenheit and Celsius.

Use the < SELECT > buttons to navigate to the Limiter Threshold parameter. Use the VALUE up/down buttons to choose dBu (DSP output) or Vpk (Amp output).

Sound travels at different speeds depending on the density of the surrounding air it is traveling through. Cold air is denser than warm air thus, travels slower than it would if the air was warmer. Temperature can have a major influence with greater distances, particularly with respect to widely separated speaker arrays surrounding the audience for example. Temperatures might vary wildly between an indoor environment and an outdoor evening environment for example.

$$ V = 3 3 1 m / s + (0. 6 m / s / C) ^ {*} T $$

The speed of sound at room temperature is 346 meters per second. At freezing temperatures sound travels at 331 meters per second. V is the speed of sound and T is the temperature of the air. This formula finds the average speed of sound for any given temperature (celcius). The speed of sound is also affected by other factors such as humidity and air pressure.

On power-up, the Dx46 boots and displays the run-time screen. The current preset memory location and name are displayed as well as the configuration on which the preset is based.

Electro-Voice Dx46

U01 Default User Preset 1 FREE CONFIGURATION

CAUTION: Before operating the sound reinforcement system, and any time a new preset is recalled, check the configuration display to make sure that it is appropriate for your system and that connections to your system are correct for the current configuration. Failure to do so could cause unexpected results or damage to the system or its components.

The LCD display's contrast and button brightness can be adjusted in the Setup Menu (see page 22) to accommodate different viewing angles. Additionally a screensaver can be activated. The screensaver dims the brightness of the LEDs and buttons to 50% about 1 minute after the last action at the front panel. Additionally an floating EV logo is shown instead of the run-time screen.

Setup: DISPLAYContrast:0 Brightness:1Screensave: disable

5.2 Level Meters

INPUT SIGNALS

During operation, the left and right input level meters display the signal present at the Dx46's analog and Digital inputs. The Dx46 does not itself have input level controls. Proper input level setting is accomplished by setting the output level from the (L / R) bus outputs from the connected mixer or other audio source. Optimal signal-to-noise performance is obtained when the nominal (average), input level consistently lights the +6dBu (green) and +12dBu (yellow) LED indicators. As the Dx46 is a digital audio device – and digital clipping produces very unpleasant results – the Clip (red) LED should never light. If it does, reduce the output level of the connected mixer. The -6dB PAD can be used for adjusting the input level also.

Illustration 5-1: Level meters of input channels

OUTPUT SIGNALS

Each output channel has an eight-segment output level VU meter. Meter response characteristics can be selected in the Setup menu:

Normal fast
Peak Hold
Slow decay.

Illustration 5-2: Level meters of output channel

The yellow segment indicates that limiting is being applied to the output channel. It is important to understand how the meters work and what they are displaying. The Output Meters are displayed as "dB to Limiter Threshold" or "dB to D/A clip". In other words, these meters will display the headroom between the output level and the limiter threshold or clip threshold of the D/A converter. When viewed in conjunction with the Gain Reduction meters, this provides a complete display of level and headroom before and after limiting has been engaged to allow system levels to be optimized. This also means that the output metering will be displayed differently depending on the limiter threshold setting. The red segments indicate clipping of the output signal and should be avoided by adjusting the Output Level setting of the output channel.

5.3 Output Gain Reduction Meters

Each output channel has a four-segment gain reduction meter that shows the effect of the output channel Limiter on output signal; from -3dB to -12dB. Output limiting can be bypassed by entering Edit mode, selecting Output Channel Limiter and selecting the Bypass parameter.

Illustration 5-3: Gain Reduction meter of output channel

5.4 Output Channel Mute Buttons

Each output channel has a lighted Mute button . Pressing the Mute button turns off the output of that channel. The button lights red as an alert. Press the Mute button again to restore the output channel's signal.

5.5 Output Channel Function Indicators

Each output channel has a four-segment function display for informational purposes only. For any given configuration possible with the Dx46, an output channel may be identified as a sub, low, low/mid, mid, mid/hi, hi or full range output. One or two adjacent LED's are displayed to indicate all possible output bandpasses. (Full range is indicated by no lit LED's.)

Illustration 5-4: Output channel function indicator

5.6 Presets Recall

The Dx46 preset memory provides 60 factory presets and can store up to 30 user presets (F01 to F60, U01 to U30). Factory presets have been designed to represent common system configurations utilizing Electro-Voice loudspeaker systems. User presets allow you to accommodate other system configurations and / or loudspeaker systems. To recall a preset, press the front panel Recall button. The display switches to the Recall Preset screen and displays the next in a list of available presets in memory.

Recall Preset: U01

5.8 Edit

Both Factory and User presets can be edited, but edited presets can only be stored in User preset locations.

STANDARD EDIT MODE

The Dx46 defaults to Standard Edit mode wherein, input and output channel parameters are appropriately linked.

Setup: EDITING Edit Mode: Standard Link: Off 

Refer to the illustrations in chapter "Configurations of the Dx46" on page 39 to see which channels are parameter-linked for each configuration. Linked parameters are always identical in value. For instance, setting a graphic eq curve for Input A, sets the same curve for Input B, if the configuration has linked stereo inputs. Either input channel can be edited; changes will be reflected in both. The same is true for parameters of linked output channels. The only exception to the linking of parameters is the Mute buttons. Output channels can be individually muted at any time, either from the Dx46 front panel or the IRIS-Net application.

FULL EDIT MODE

In the Setup EDITING menu, the edit mode can be changed to Full. In Full Edit, no parameter links are enforced, regardless of the configuration selected. Any parameter can be changed without any effect on other parameter values.

Setup: EDITING Edit Mode: Full Link: Off 

Regardless of the edit mode selected, there are two means to enter edit mode: pressing the Edit button or pressing any DSP block button. Use the < SELECT > buttons to navigate to the top line of any edit screen, and the Value Up and Down buttons to navigate to any other Edit screen. As a short-cut, press a DSP block button to jump to the last selected screen of said block and navigate as above to reach the desired screen.

Changes to preset availability, parameter availability and preset value ranges can only be set using the IRIS-Net application.

WHY ARE THERE SO MANY DIFFERENT DELAY SECTIONS?

When configuring a PA or loudspeaker system, there are a variety of different scenarios that will require time alignment or delay compensation. Some of the different scenarios are:

• Delaying a set of loudspeakers to act as under-balcony fills or delay towers in a concert PA
• Aligning a PA system to the sound source on a stage, or aligning the "tops" to the "subs"
• Timing correction to compensate for the offset acoustic centers of individual transducers within a loudspeaker cabinet
• Delay offset for one or more loudspeakers in a cluster to improve coverage and overlap effects

Some applications will only encounter a few of these needs, while others will encounter all of them, such as in a theater with a center cluster of horn-loaded loudspeakers, subwoofoers, and under balcony delay speakers.

With other DSP products, a designer must make use of only one or two delay sections, which means that a designer must carefully think about how to calculate delays, how to add offsets to individual channels so that delay section can perform multiple tasks. This can result in a confusing DSP structure and more potential for delays being adjusted improperly. The Dx46 provides dedicated delay sections to perform each of these delay scenarios independently, which provides easier setup, adjustment and programming.

SIGNAL GENERATOR

The integrated signal generator of the Dx46 can generate following signal types:

• Sine signal
  White Noise
  Pink Noise

Please refer to page 22 for details.

INPUT PARAMETRIC EQ (PEQ)

PEQ

Use the < SELECT > buttons to make the top line of the Edit screen active and the Value Up and Down buttons to navigate to the Input PEQ screen. The Dx46 provides a stereo 10-band multi-mode filter generically referred to as the Input PEQ (Parametric Equalizer).

IN A:PEQ1	Active
Type: Hipass	F: 20000.0Hz
Slope: 12dB/oct	Q: 2.0

The Input PEQ is a very powerful and complex set of multi-mode filters. Care must be given configuring these filter bands, as they interact and can produce unexpected results. Using the IRIS-Net application is strongly recommended to set all but the most simple eq curves.

Each band of the Input PEQ can be configured for a specific filter type, frequency, slope or Q and gain setting. Attention must be paid to the ultimate output gain through the rest of the Dx46's audio path, as it is possible to boost frequency ranges to the point where the internal or external audio paths of the system may be clipped. Monitoring the output VU meters of the Dx46's output channels will indicate internal clipping; the input meters of connected amplifiers should do the same. The following section details the type of filters that can be selected for each of the Input PEQ's 10 bands and their parameters.

Table 5-7: Input Channel Parametric EQ

Filter type	Frequency	Slope	Resp / Q	Gain
Loshelv	20 to 20000 Hz	6dB/oct.	-	-18.0 to +12.0 dB
		12dB/oct.
Hishelv		6dB/oct.	-
		12dB/oct.
PEQ		-	0.40 to 40
Lopass		6dB/oct.	-	-
		12dB/oct.	0.4 to 2.0	-
Hipass

Low shelf (Loshelv)

The Low-shelf filter is a "hinge" type; in that frequencies below its frequency setting can be boosted or cut; hinging on the cut-off Frequency. The amount of boost or cut (Gain), and the extent of width of the filter's transition band (Slope), are determined by the low-shelf filter's settings. (See Response/Q and Gain.) Use the < SELECT > buttons to navigate to the filter setting you wish to adjust, and the Value Up and Down buttons to alter these settings. Press the Value Up and Down buttons once to increment values by one unit, or press and hold to scroll rapidly through available values. (Values do not wrap around.)

Hi shelf (Hishelv)

The Hi-shelf filter is a "hinge" type; in that frequencies above its frequency setting can be boosted or cut; hinging on the cut-off Frequency. The amount of boost or cut (Gain), and the width of the filter's transition band (Slope), are determined by the hi-shelf filter's settings. (See Response/Q and Gain.) Use the < SELECT > buttons to navigate to the filter setting you wish to adjust, and the Value Up and Down buttons to alter these settings. Press the Value Up and Down buttons once to increment values by one unit, or press and hold to scroll rapidly through available values. (Values do not wrap-around.)

PEQ

PEQ is shorthand for Parametric Equalizer. A parametric equalizer has three parameters that determine the frequencies that are affected by it; Center Frequency, Q (filter-width) and Gain. Parametric filters are ideal for identifying, isolating and correcting problematic frequency ranges. The Frequency parameter determines the center of a range of frequencies that will be adjusted by the PEQ. The Q parameter will determine the range of frequencies adjacent to the center frequency that will also be effected; the greater the value, the smaller the range of adjacent frequencies that will be effected. The gain parameter determines the amount of boost or cut that is applied to the frequencies

that are affected by the filter. Use the < SELECT > buttons to navigate to the filter setting you wish to adjust, and the Value Up and Down buttons to alter these settings. Press the Value Up and Down buttons once to increment values by one unit, or press and hold to scroll rapidly through available values. (Values do not wrap-around.)

Low-pass (Lopass)

The Low-Pass filter determines the ultimate high frequency that your sound reinforcement system is allowed to reproduce; given the capabilities of amplifiers, speakers and transducers. The low-pass filter is useful for reducing excessive high frequency energy that can create stress on high frequency transducers and listener fatigue. Available parameters are Frequency and Slope. The frequency parameter determines the frequency above which frequencies will be attenuated. The slope determines how quickly frequencies above the cutoff frequency will be attenuated. (See response curve.)

Use the < SELECT > buttons to navigate to the filter setting you wish to adjust, and the Value Up and Down buttons to alter these settings. Press the Value Up and Down buttons once to increment values by one unit, or press and hold to scroll rapidly through available values. (Values do not wrap-around.)

High-pass (Hipass)

The Hi-Pass filter determines the ultimate low frequency that your sound reinforcement system is allowed to reproduce; given the capabilities of amplifiers, speakers and transducers. Available parameters are Frequency and Slope. The frequency parameter determines the frequency below which frequencies will be attenuated. The slope determines how quickly frequencies below that will be attenuated. (See response curve.) Use the < SELECT > buttons to navigate to the filter setting you wish to adjust, and the Value Up and Down buttons to alter these settings. Press the Value Up and Down buttons once to increment values by one unit, or press and hold to scroll rapidly through available values. (Values do not wrap-around.)

INPUT GRAPHIC EQ (GEQ)

Use the < SELECT > buttons to make the top line of the Edit screen active and the Value Up and Down buttons to navigate to the Input GEO screen. The Dx46's input signal path includes a stereo 31-band graphic equalizer after the stereo 10-band PEQ in the signal path. This DSP block can be used for very precisely identifying, isolating and correcting problematic frequency ranges. Keep in mind that changes

to the Input GEQ will be interactive with adjustments made in the Input PEQ. Unexpected results can occur.

Overview

Press the < SELECT > buttons to move the cursor down into the GEQ frequency adjustment field. Subsequent presses of the < SELECT > buttons will move the cursor forward or backwards through the frequency adjustment field; from band to band. The selected frequency's "fader" is highlighted in the display. As each band is selected, its center frequency and current cut/boost setting is displayed on the top line of the LCD display.

To adjust the amount of boost or cut for a selected frequency band, select the band with the < SELECT > buttons and press the Value Up or Down buttons as required. The LCD display will reflect your changes by moving the selected frequency band's "fader" up or down.

INPUT DELAY

DELAY

The Dx46 offers an input delay that is useful for compensating for different arrival times of sound originating from loudspeakers that are closer or further away from the listener than others. A technique known as the Haas Effect allows the operator to create the illusion that all of the sound has originated from the stage even though additional speakers have been placed around the room.

HINT: The Input Delay parameter is especially useful for delay lines. In this case the required delay, depends only on the position of the delay line and is identical for all ways, e.g. output channels of the Dx46. By editing the Input Delay parameter the delays of all output channels routed to this input are adjusted automatically.

Available Input Delay parameters are Delay, Units and Active/Bypass. The Delay parameter allows the user to determine the Delay time values and the Active/Bypass parameter to activate or deactivate the delay.

To access the Input Delay, press the Delay button found on the input processing menu. Subsequent button presses will toggle the display between Input A and Input B. Input delay parameters are accessed using the button to navigate between Delay, Unit and Active/Bypass using the VALUE up/down buttons to adjust values. Following table shows the available units of the delay.

ARRAY DELAY

Use the < SELECT > buttons to make the top line of the Edit screen active and the Value Up and Down buttons to navigate to the Array Delay screen. In the ARRAY CONTROL section a delay is available for each output.

HINT: The Array Delay parameter can be used for adjusting the individual cabinets within a loudspeaker cluster, such as a subwoofer array or a center loudspeaker cluster. For example, in a speaker cluster consisting of two horn-loaded loudspeakers, it is helpful to apply 3-5 mS of delay to one of the loudspeakers in the cluster to improve the coverage in the overlap of the horn patterns. Additionally, the array delay provides a convenient section to apply dedicated delay to individual subwoofer cabinets to create gradient or beam-formed arrays.

OUTPUT X-OVER

X-OVER

The Dx46's crossover is an advanced frequency division process that is accomplished by applying a variety of high-pass and low-pass filters to a predetermined set of crossover points. Speaker systems are generally made up of several drivers that are dedicated to a specific range of frequencies that result in the efficient reproduction of the audio spectrum and a smooth sound. The Dx46 crossover routes frequencies to the appropriate drivers to accurately reproduce sound. The crossover network can also be sure that low-frequency energy is not accidentally routed to the mid-range or tweeter drivers that may result in damage. Available Dx46 crossover parameters are Type and Frequency.

To access the Crossover screen, press the X-Over button. Subsequent button presses will toggle the display between OUT1 to OUT6. Use the Value Up and Down buttons to navigate between the X-Over HIPass, X-Over Lopass, X-Over Delay and FIR Filter screens.

OUT 1:X-Over Hipass Type:12dB Butterworth F:80.0Hz Trim:3.0dB

The Dx46 Crossover offers a variety of Hipass and Lopass filters depending on the configuration output selected along with a variety of selectable filters and frequency ranges that are adjustable using the up/down VALUE arrows.

Table 5-13: Crossover parameters

Parameter	Description
Type	Type offers list of selectable slopes/response Q's • Thru • 6dB • 12dB, Q = 0.5 to 2.0 • Bessel: 12 dB, 18 dB or 24 dB • Butterworth: 12dB, 18dB or 24 dB • Linkwitz-Riley: 12dB or 24 dB
Frequency	Frequency offers a selectable frequency range from 20 to 20000 Hz.
Trim	The amount of boost or cut

Hi-Pass/Lo-Pass

The Dx46 Hi-Pass and Lo-Pass filters are determined by selecting the Type from the list of parameters, (see list above) and by choosing a frequency range between 20.0 Hz to 20,000Hz. (See above). Additionally the Trim parameter can be used.

The crossover filter generally consists of a low pass filter in one channel and a high pass filter in the adjacent channel. This is where the frequency x -over filter's Hi-Pass parameters are set. The Hi-Pass frequency parameters are linked to the corresponding Lo-Pass frequency parameter unless in Full Edit Mode or using the Free Configuration option. Please refer to the Configuration section of this manual for details on the effect different Configurations have on channel linking. The Type parameter defines the filter characteristics of the crossover Hi-Pass filter. Different slopes and filter responses (6dB, 12dB with different Q values, Bessel, Butterworth, Linkwitz-Riley) are available. Again, the Hi-Pass frequency parameters are linked to the corresponding Lo-Pass frequency parameter depending on the Configuration that is currently being used. High pass frequencies are set with a pre-determined frequency that attenuates frequencies below (the crossover point). On the contrary, a Low Pass filter passes frequencies below the crossover point and attenuates those above.

Crossover Alignment Delay

To access the X-Over Delay screen, press the X-Over button found on the output processing menu. Subsequent button presses will toggle the display between OUT 1 to OUT 6. Use the Value Up and Down buttons to select the X-Over Delay screen.

HINT: The X-Over Delay parameter is used for the alignment of transducers within cabinets. Optimized delay values are included in Electro-Voice Speaker Settings and should not be edited.

Use the button to navigate between the X-Over Delay parameters. Adjust the values of each parameter using the up/down VALUE arrows.

Table 5-14: X-Over Delay parameters

Parameter	Description
Delay	Use this parameter to compensate for physical offsets of the acoustic centers of transducers within a loudspeaker cabinet. For example, due to cabinet construction, the acoustic center of a high frequency transducer may be mounted behind or in front of the acoustic center of the low frequency transducer. The Delay parameter can align the audio signal between the multiple transducers within the loudspeaker.
Unit	The user may select between time and distance display. Distances are automatically converted into delay times. This calculation also includes the influence of the environmental temperature based on the Temperature parameter in the Setup Menu.
Active/Bypass	Setting this to Bypass disables the Crossover Delay.

FIR FILTER

To access the FIR FILTER screen, press the X-Over button found on the output processing menu. Subsequent button presses will toggle the display between OUT 1 to OUT 6. Use the Value Up and Down buttons to select the FIR FILTER screen. The FIR FILTER screen shows the Name of the currently used FIR filter.

Use the button to select the Active/Bypass parameter. Activate or Bypass the FIR filter using the up/down VALUE arrows. Configuration of the FIR filter itself is only possible using the IRIS-Net software.

OUTPUT DELAY

To access the Delay screen, press the SPEAKER Delay button. Subsequent button presses will toggle the display between OUT 1 to OUT 6.

HINT: The Dx46's output delays can be used to compensate for the positioning of cabinets or speaker arrays relative to each other or the original sound source, for example aligning the PA to the stage or aligning the full-range loudspeakers to the subwoofoers. The Output Delay parameter determines the delay time of the corresponding channel or the distance between different loudspeaker clusters.

OUT 1:Output Delay Active Delay:7.0 Unit:ms 

Use the buttons to navigate between Active/Bypass, Delay and Unit. The values for each parameter can be adjusted using the up/down VALUE arrows. The delay time or physical distance is displayed in milliseconds, microseconds, feet, inches, meters, or centimeters.

OUTPUT LEVEL

The Output Level is used to adjust master output levels. To access the Output Level screen, press the Level button. Subsequent button presses will toggle the display between OUT 1 to OUT 6.

OUT 1:Level/Limiter  
Level: 6.0dB Polarity:Inv  
Amp: TG-7 (0 dBu) 

Use the button to navigate between the selectable Level (-100.0dB to +6.0dB), Polarity and Amp parameters. Adjust the value by using the up/down VALUE arrows.

Limiter threshold values are determined by the amplifiers and loudspeakers that are used in the system. One important consideration in setting the limiter threshold value is the input sensitivity and gain of the connected amplifiers. Because different amplifiers can have different sensitivities, it is common to need to calculate the limiter offset to a factory preset based on the amplifier sensitivity. The Dx46 offers a unique solution to this problem with the Amp parameter. All Dx46 Factory Presets include limiter threshold values. You may use the Amp parameter to select the model of Electro-Voice amplifier that you are using and the limiter threshold offset will be automatically calculated based on the amplifier gain and sensitivity. When an amplifier is selected from the list, the actual Threshold parameter will be locked to ensure that proper settings are maintained. It is very important to ensure that the proper amplifier is selected from the list, as an improper selection can result in incorrect Limiter settings for your system and may result in system damage. If a non-Electro-Voice amplifier is used in the system, selecting "User" from the amp list will allow the Threshold setting to be directly edited, however, the amplifier documentation should be consulted so you can calculate you limiter offset (if any) as needed. The Amp parameter is only available when using a Factory Preset.

OUTPUT LIMITERS

The Dx46's output channel limiters prevent audio signals from exceeding a set level. Press the Level button to change the output channel. Hold-down the Level button for some seconds - you will then be presented with the Limiter screen.

Use the < SELECT> buttons to navigate between Active/Bypass, Type, Threshold (-9.0 dBu to +21.0 dBu), Attack (0 ms to 50 ms) and Release (10.0 ms to 1000.0 ms). Adjust the values of each parameter using the up/ down VAL-UE arrows. The parameter Type allows selecting the used loudspeaker type. By selecting the type Sub, Lo, Mid or Hi the settings of the parameters Attack and Release are adjusted automatically. Select the type User for setting the parameters Attack and Release manually. The value of the parameter Threshold depends on the used speakers and the input sensitivity / gain of the used amplifiers.

TEMP Limiter

Additionally to the Peak-Limiter for the outputs there is a TEMP limiter available for each output. Parameters for the TEMP limiter are included in speaker settings files (.sps) and can be loaded to the device using the IRIS-Net control software.

6 Configurations of the Dx46

The Dx46 offers 7 pre-defined configurations. A configuration is a basic setting that includes the routing of inputs and outputs, the function of the outputs (Sub, Lo, Mid, Hi, Full Range) including basic X-Oover filter settings, and different channel/parameter linking schemes. The active configuration is defined by the selected preset i. e., each preset is based on a specific configuration which is also displayed next to the preset number and preset name. Each output employs two X-Over filters that can be assigned to a variety of filter types and slopes. Each output channel provides 5 additional filters which can be used as parametric EQs, Low-/ High-shelving filters, or Lo-Pass and Hi-Pass filters, and also as All-Pass filters. In addition to a gain control for adjusting the output level and a polarity switch, each output is monitored by a digital limiter with adjustable threshold, attack and release.
