Frequently Asked Questions - DMP808 PHONIC

Why is there no audio output?

Check that the output channels are unmuted and routed correctly in the matrix. Verify input signals are present and levels are up. Ensure no excessive compression or limiting is applied. Also confirm that the power switch is enabled and the unit is not in standby.

How do I connect the DMP808 to my computer?

Use a standard CAT5/6 Ethernet cable to connect the DMP808's Ethernet port to your network or directly to your computer. Set the unit's IP address via rear panel DIP switches or software. Install the Asystems control software, enter the device IP, and log in with default credentials (User: USER_1, Password: ASYSTEMS).

What should I do if the front panel volume knobs don't work?

Check DIP switch pole 6 on the rear panel: set it to the ON position to enable panel VR controls. If still not working, verify that individual channel knobs are not disabled in the software's Control Panel page.

How can I restore factory settings?

Unplug the power, set DIP switch pole 7 to ON, reconnect power and wait for startup, then set pole 7 back to OFF. This resets all settings including user names and passwords.

Can I use the DMP808 with Dante?

Only the DMP808D model includes a Dante expansion card. For standard DMP808, an optional card can be installed in the Digital I/O expansion slot. Use Audinate Dante Controller software to route audio signals.

How do I update the firmware?

Set DIP switch pole 1 to ON. Connect the unit to the PC software. Navigate to Global Settings > Utility. At the bottom, click 'Update' and select the firmware file from Asystems website. Wait for the process to complete, then set pole 1 back to OFF.

What is the purpose of the GPIO connections?

GPIO IN allows connection of an RM-4 remote for preset recall. GPIO OUT provides 0V/5V for external power control. These ports are used for remote on/standby and preset selection.

How do I set a fixed IP address?

You can set the IP via hardware (DIP switches and rotary Unit ID) or software. For hardware, set DIP pole 2 to ON, then use poles 3/4 and the rotary to define the last host byte in hexadecimal. The default IP when using hardware mode is 192.168.0.x. Refer to the manual's conversion table.

Why does the audio distort?

Check if any Clip LEDs are red (input or output). Reduce input gain or lower the master output level. Ensure no processor settings (e.g., compressor threshold) are too aggressive. Also verify that the input signal level is not overloading the analog inputs.

How can I control the DMP808 remotely?

You can use the Asystems control software over Ethernet. For physical remote controls, connect the RM-4 (preset recall) to the GPIO port, or daisy-chain up to 8 RM-6E units (each with 6 programmable functions) via the Peripheral Ethernet port.

Pin 2: Link to Pin 1

Pin 3: Hot (+)

GLOSSARY

The following are a few words that may serve you well while reading this manual. These aren't in depth explanations, but should hopefully give you the basics and a place to start.

Balanced Connections - balanced connections offer three conductors, carrying a ground, an in-phase signal, and an out-of-phase signal. Once the two signals are sent from one device to another, the out-of-phase signal has its phase inverted and the two signals are combined. Any interference picked up along the way is removed through to phase cancellation. This allows cables to be run over long distances without collecting excessive noise on the way.

Compressor - a Compressor reduces signals over a user-defined threshold by a user-defined amount/ratio.

Dynamic Processor – is any kind of processor that dynamically – or in real time – adjusts signal properties.

EQ – Equalizer – is a device or process that allows users to boost or attenuate audio signals at specific frequencies.

Euroblock – These types of inputs allow for self-wiring of connections for permanent installations. Check the "Getting Started" section for more information on wiring.

GEQ – Graphic Equalizer – is in essence the same as an equalizer, but this title is reserved for equalizers with more 'bands' than the typical EQ. While a typical channel EQ may only allow for 3 or 4 frequencies to be adjusted, a graphic equalizer may allow for 31 different frequencies.

GUI – Graphical User Interface – this is the remote PC software used for the DMP808.

HPF – High Pass Filter – a high pass filter will cut or significantly reduce all audio signals below a particular user-defined frequency, allowing – as the name suggests – high frequency sounds to pass through.

High Shelf Filter – the high shelf filter will reduce or increase all audio signals below a particular frequency. The level at which the signal is boosted/attenuated is determined by the user.

Limiter - work just as compressors do; however with an input to output signal ratio permanently set to infinity-to-1.

LPF – Low Pass Filter – a low pass filter will cut all audio signals above a particular user-defined frequency, allowing low frequency sounds to pass through. This is significantly useful when using subwoofer speakers on particular outputs.

Low Shelf Filter – the low shelf reduces or increases the level of audio signals below a particular frequency selected by the user. The level at which the signal is altered is also set by the user.

Network – a network is a series or group of computers that are interconnected so as to share information. In the case of the DMP808, the network allows for remote operation of the device using our Windows-based computer.

Noise Gate - a noise gate is a dynamic process that turns off or significantly attenuates the audio signal passing through it when the signal level falls below a user adjustable threshold.

Unbalanced Connections – unlike balanced connections, unbalanced connections only have 2 conductors: one for the signal and one for the grounding. This, unfortunately, makes them more susceptible to noise and interference.

DANTE CONNECTIVITY (DMP808D ONLY)

The Dante expansion card should come pre-installed with the DMP808D (and is not included with the DMP808). This is an optional component that is not included on all versions of the DMP808.

The "Primary" port on the Dante card can be connected to your network router. The Secondary port can be connected to the Primary port of additional units. Alternatively, all units can be connected to the router using their "Primary" ports.

The Audinate Dante Controller can be downloaded through their website (www.audinate.com). This is used to route the network signals from numerous Dante-enabled devices. Each device will show up as its own independent signal with input and output channels listed. All units will be automatically discovered by the software.

Signals can be routed internally using the instructions found in section 5. The actual network input signals received by your DMP808s are determined by the aforementioned Dante Controller software. It should be noted that each Network input mix can only have a single source assigned to it.

Connecting additional units to your network will automatically be recognized by the software, allowing any of these systems to have their signals routed throughout the network.

In addition to the regular network routing of signals, the Dante expansion cards are compatible with Audinate's

Virtual Soundcard software which allows for recording of audio to the computer and playback of audio from the computer. At the time of publication, this a permanent license for this software is available for \$29.99. The controller software is completely free on Windows 7 (SP1), Windows 8.1, Windows 10, OSX 10.10.5 (Yosemite), OSX 10.11.6 (El Capitan) and macOS 10.12 (Sierra).

GENERAL SETTINGS

RESTORE FACTORY SETTINGS

1. Unplug the DMP808's power cable.
2. Switch POLE 7 on the rear panel DIP Switches to the ON position.
3. Replace the power cable and power on the DMP808. Wait for the start up procedure to complete.
4. Switch POLE 7 to OFF.
5. Now your DMP808 is restored to the factory default settings.

NOTE: A factory restore is particularly helpful in the event that user names and passwords are forgotten. Restoring to factory default settings will restore user names back to default values.

ACTIVATING VR CONTROLS

Use pole 6 on the rear panel DIP switch to turn the front panel controls on and off. When OFF, the rotary volume controls on the front of the DMP808 will be deactivated. In the event that controls are not functioning, be sure to check this before taking further action.

In addition to this switch, each and every individual control can be deactivated within the software. Within the Control Panel page, the ON/OFF buttons at the very bottom of each channel will allow you to turn the front panel rotary controls on and off.

FIRMWARE UPDATE

When performing a firmware update, a few steps need to be followed. First of all, set the first pole of the DIP switch to the upper-most position.

A connection needs to be established between the DMP808 system and the Windows remote software. After this is done, enter the Global Settings tab and the Utility menu. At the very bottom of the page, click the "Update" button under the Firmware section. Users will be prompted to select the firmware file (available on the Asystems website) and the firmware update process will begin.

HOW TO SET THE SYSTEM IP ADDRESS

Connecting the DMP808 to a computer for remote operation requires the user to enter an IP address for the unit. There are two controls that help determined the IP address of the DMP808 matrix processor. The first is the UNIT ID rotary control, that lets you select 0 – 9 and A – F. The second is the DIP switch located directly beside the rotary switch. The 3rd and 4th poles of the DIP switch can be used to set a numerical value between 0 and 3. These combine with the UNIT ID rotary switch to form a hexadecimal value for the last value of the IP address (as indicated below).

Value The 3rd PIN The 4th PIN

0 OFF OFF

1 ON OFF

2 OFF ON

3 ON ON

The configurable range for the last digit is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F.

The unit ID configuration mechanism of DMP808 is developed based on "hexadecimal numeral system". Therefore, a scientific calculator may be required when setting the unit ID of the IP address for DMP808. Below is the procedure for setting the unit ID:

1. Define the IP address for your DMP808.
2. Convert the decimal value of the host bits of the IP address to a Hexadecimal value (consult the provided table).
3. Set PINS 3 and 4 on the 8-PIN DIP switch according to the first digit of the converted Hexadecimal value.
4. Set the rotary switch according to the second digit of the converted Hexadecimal value.

Example: To set an IP address of "192.168.0.21" on your DMP808, the rotary control should be set to 5 and the DIP switches 3 and 4 should be set to ON and OFF, respectively. This sets a hexadecimal value of 15, which - converted to decimal - is 21. Consult the included chart for hexadecimal to decimal conversion.

Channel In Matrix

This page offers matrix mixing for the Analog inputs to the Channel Input mixes. Any of the input sources can be assigned to the individual “Channel Input” mixes.

Each of the possible input matrix sources can have a number of controls available. These include:

Attenuation/Fader: Adjust the input level of each of the individual signals.

Panning: These will let you adjust the left/right mix of the incoming signals.

ALC: This button will assign the DMP808's Auto Level Control to the corresponding input signal.

Duck: Pushing this button will apply the ducking feature to the corresponding input signals. The duck function can be activated as ducker 1, ducker 2, or off, the settings of which are decided by their respective menus.

INV: This button will invert the phase of the corresponding signal.

On: This button allows you to turn the corresponding input signal on and off. When turned off, the signal will not be sent to the Input Channels selected.

Routing: Each of the 12 analog inputs can be assigned to the DMP808's 8 matrix channels. These input channels are what will be used for the DSP processing and will be then routed to your output mix.

Mix Matrix

Each of the 8 Mix Ins and the 8 Mix Outs can be tweaked before being sent to the main outputs.

Attenuation/Fader: Adjust the input level of each of the individual input signals or matrix mixes.

Auto Mixer: This button on each channel will activate automixing on the corresponding channel. When deactivated, the channel is set to manual mode and will work independently to the automixer function. When set to Auto, 'auto' channels will compensate for changes in levels to adhere to the selected 'target level' (see "SEL").

Auto Mixer Response Time: The time to automixer takes to activate can be selected using the pull-down menu to the left of the 'Auto' buttons.

SEL: The select button on each Mix Out will allow the user to use the selected channel's output level as the target level for the automixer function.

INV: This button will invert the phase of the corresponding input or matrix signal.

On: This button allows you to turn the corresponding input / output signal on and off. When an input is turned off, the signal will not be sent to any of the matrix outputs selected. Turning off a Mix Out will effectively disable that output.

Routing: Each of the analog inputs and matrix inputs can be assigned to the DMP808's output mix.

Clear: The 'CLEAR' button to the left of the routing section will allow users to instantly clear all routing selections.

Link: The 'LINK' pull-down menu allows users to assign the corresponding channel to a particular group. Linking two or more mixes in a single group will link the automixer parameters of those particular mixes.

Signal Generator

The Channel Inputs and Matrix Output can have a signal generator applied to them. The option can be found in the Channel Matrix and Mix Matrix pages by right clicking the mouse. The signal generator can be activated with the "ON" buttons and assigned to the appropriate mixes using the matrix/channel select section below the controls.

There are 4 different signals available, including White Noise and Pink Noise – ideal for setup of systems – and sine and sweep waves – for testing of equipment and for general setup purposes.

Sine: The sine wave can be selected between 20 Hz and 20 kHz. The signal level can also be adjusted, and the signal can be turned on and off.

Sweep: When using the sweep wave, a lowest and highest frequency can be selected. The sweep wave will move between these frequencies and small increments.

The hold time for each frequency can be selected by the

users. There are also controls for adjusting the signal level and turning the sweep wave on and off.

Pink Noise: The pink noise function includes level controls and on/off button.

White Noise: Like the pink noise, the white noise only offers level controls and an on/off button.

Network Matrix

Any of the incoming input signals can be assigned directly to the Network output mixes. The network matrix pages are only used when the Asystems network expansion card is installed in the DMP808. Attenuation: Adjust the input level of each of the individual input and output mixes.

Panning: These will let you adjust the left/right mix of the available mixes.

ALC: This button will assign the DMP808's Auto Level Control to the corresponding input.

Duck: Pushing this button will apply the ducking feature to the corresponding mix. The duck function can be activated as ducker 1, ducker 2, or off, the settings of which are decided by their respective menus.

INV: This button will invert the phase of the corresponding input or matrix signal.

On: This button allows you to turn the corresponding input signal on and off. When turned off, the signal will not be sent to any of the matrix outputs selected.

Routing: Each of the 12 analog inputs, 8 matrix inputs and 8 matrix outputs can be assigned to the DMP808's 8 network outputs. These channels will appear as Network Input connections in any networked Asystems DMP, DMA or NT series devices.

Control Panel

The control panel menu offers complete control of output channels. This menu includes level, gain controls, metering, and a host of other parameters that can be edited.

Channel Name: A preselected channel name can be viewed or edited in this screen.

Fader: The input level can be adjusted using this onscreen fader.

Meters: The input and output signal level of the channel can be viewed through these meters. They can be adjusted between pre- and post-fader meters.

Gain Reduction: The gain reduction meter will provide a real-time indication of any reduction in gain applied by the internal DSP processes of the DMP808 (including compressors-limiters, equalizers, etcetera).

Limiter: This button will activate the internal limiter function for the corresponding channel.

Duck: Activate the 'ducking' feature by pushing this button. The duck function can be activated as ducker 1, ducker 2, or off, the settings of which are decided by their respective menus.

INV: This button will invert the phase of the corresponding signal.

CH ON: This button will turn the corresponding channel on and off.

Network

When using the DMP808 remote software – either within the local area network or through the internet – the network settings need to be set appropriately to allow external computers to identify and connect to it.

The IP address of DMP808 can be set via the system hardware (rear panel) or the software (remote control software).

Set via System Hardware

When the IP address is set via the hardware, the on screen display will show the following:

Device Name: The name of the current device is found here, and it can be adjusted by the user, if necessary.

IP Address: The actual IP address of DMP808 will automatically be detected and shown here. User can manually adjust the IP address through the rear panel.

Set via Software

Device Name: The name of the current device is found here, and it can be adjusted by the user, if necessary.

IP Address: The actual IP address of DMP808 will automatically be detected and shown here. User can manually adjust the IP address through the rear panel.

Security

This tab can be found under the Network Settings menu. The security tab provides a means of securing the DMP808 against unauthorized changes. Through the DMP808's onboard software these accounts can be created for use of the Asystems remote software.

Global Settings

Analog In

Each of the analog inputs can have +48V of phantom power applied to it, ideal for condenser microphones. This menu also allows the user to trim the signal slightly if levels are too excessive. A high-pass filter can also be added to each of the analog inputs to help remove stage rumble and other unwanted noise.

Global In On/Off

This menu provides buttons for each individual input, including analog input, network input, EX IN input and signal generator.

Ducker

The ducker allows a signal to temporarily attenuate below another signal when said signal activates the ducking feature. This is useful when making announcements and other such times when a signal needs to be heard clearly. The ducker can be activated on input and output channels by pushing the 'Duck' buttons found in the individual Matrix control pages. There are two of these 'duckers' total on the DMP808.

Source: This is used to select the source of the duck function; ie. the trigger signal. When the selected source's signal rises to a user-selected level, the currently selected 'duck' signals will attenuate at the selected level.

Threshold: This determines the level that the source signal needs to be before the ducking function will be activated.

Depth: This determines how much the selected 'duck' signals will be attenuated.

Attack: The attack time is the time it takes for the ducking feature to kick in after the source signal passes the selected threshold.

Release: The release time control will determine the time the 'duck' feature will remain active as the source signal drops back below the set threshold.

ALC - Auto Level Control

An autoleveler will allow users to dynamically change the level of an input or output signal to match a predefined level set by the user. The autolevel function can be activated for each individual mix in the matrix pages. The settings for these autolevelers can be found within this ALC menu.

In Target: The target level setting allows users to select the desired signal level for their autoleveler. All signals that are processed by the autoleveler will essentially aim for the target level.

Below Target: The below target threshold of the autoleveler is the point at which the autoleveler will kick in. Signals below the threshold will not be affected, but signals above will be have their gain increased.

Ratio: The ratio is the input level change in decibels to the output level change in decibels.

Increase Gain: The increase gain determines the amount that the signal can be increased to meet the target level. This helps prevent sudden, alarming changes in audio level.

Decrease Gain: The decrease gain works the same as the decrease gain, but in reverse. It determines the amount a signal can be cut.

Hold Time: This determines the time the ALC will remain engaged after the signal falls back below the determined threshold.

Compressor/Limiter

This menu allows compressors and limiters to be applied to the channel output

Limiter Threshold: This control determines the threshold for the limiter function. This means that no signal will surpass the selected threshold, being 'compressed' at a ratio of infinity:1.

Compressor Threshold: Use this control to set the threshold of the compressor function. Any signals that surpass the selected threshold will be compressed at the selected ratio.

Compressor Ratio: This control can be used to set the ratio for the compressor. The ratio is expressed as :

.

Compressor Attack: This control adjusts the attack time of the compressor, essentially determining the time taken for the compressor to kick in after it passes the selected threshold.

Compressor Release: The release control determines the time the DMP808 will wait before disengaging the compressor when the signal bypasses the selected threshold.

Side Chain HPF: This allows users to set a high pass filter on these channels to essentially help rid these channels of low-frequency noise.

System

System Clock: This menu allows you to select the internal sampling rate of the DMP808. Users are able to select between either 44.1 or 48 kHz. You can also choose to take clock settings from the audio networking feature. The ENTER button must be pushed to confirm.

Power Settings: There are three power settings on the DMP808. The software power can be turned on and off, essentially enabling the DMP808 to be turned on and off via the software – including event scheduling. The hardware power can be selected on and off, essentially allow the unit to be activated and deactivated using the hardwired switch on the front of the DMP808.

Relay I/O (GPIO)

The general purpose interface output is used to remotely control the DMP808. When properly setup, you can turn the power on or put the system in standby mode.

RM Control

This page offers a number of assignment options for the optional Asystems RM remote controls. More details can be found on the following pages.

Utility

All of the DSP processes can have their settings saved, while there are a number of factory presets available, users are always encouraged to find their own settings and save them for later use. The custom scene settings of the DMP808 are stored in the hard drive of the computer connected. After the firmware is updated, the initialize button can be selected to reset the device. Save any settings (or "scenes") before initializing the system.

RM-4 PRESET RECALL REMOTE

With a single RM-4 you will be able to recall up to 4 independent presets.

The RM-4 can be wired to the "Preset" section on the rear of the DMP808.

As shown, there are pins for each of the 4 preset buttons on the RM-4, as well as a grounding pin. Each of the 4 pins corresponds with a user-selected "Scene" within the control software.

Suggested wiring:

SETUP AND OPERATION

To utilize the RM-4, you simply need to assign a preset to each of the buttons. This is done within the Control Software of the DMP 808. First, enter the "Global Settings" menu and find the GPIO submenu. Here you will find the "Preset" panel (shown below). Each of the pins on the rear of the device will correspond to the Ports listed here. You can then select which "Scene" (or preset) you wish to assign to that port.

The pre-saved scenes are all listed within the Utility menu. Scenes can be saved (and recalled) in this menu. The "No" in the Preset window on the GPIO page will correspond with the 'Scene' numbers found here. The Subject in the Preset window will be updated automatically.

A single preset can be recalled at any one time. The button selected on the RM-4 will lock down, releasing any other preset button that may have previously been selected.

RM-6E PROGRAMMABLE REMOTE

With a single RM-6E you will be able to control up to 6 independent functions including gain control, channel muting and matrix mixing. Up to eight RM-6Es can be utilized at any one time.

WIRING

The RM-6E has an "IN" port that can be connected to the RJ-45 "Peripheral" connector on the DMP808 series of digital matrix amplifiers and processors. This is done using a typical CAT5/6 cable.

A second RM-6E can then be daisy-chained off the first by connecting the "LINK" RJ-45 connector on the first to the "IN" connector on the second. This can then be repeated for a third, a fourth, and so on. You can use a maximum of 8 RM-6E's together with your DMP808.

SETUP

The rear of the RM-6E features 3 DIP switches that can be utilized for identification of the unit. These correspond with the 8 ports available within the DMP808 software. The pin identifications and their corresponding ports are as follows:

To assign a function to any of the RM-6E's buttons, you will need to enter the software of your DMP808. When in the software, navigate to the "Global Settings" tab. Within this menu there is an "RM Control" submenu that offers control of the RM-6E programmable remote controls.

The "Port" option at the top of the page will correspond with the port options found above. When the corresponding port is selected, the 6 rows in the lower-half of the page can be used to determine the operation of each individual button on the RM-6E. Available functions are: "Gain Control", "Channel In Mute", "Channel Out Mute" and "Matrix Mixer". The first three functions also have a "Source" option that simply lets you select from an available channel that you can then control. The "Matrix Mixer" function has further options, allowing you to select from the applicable matrix mix and input source.

Below the "Port" option in the control software, there is also a "Lock" option. When a port is "locked", the corresponding functions of the RM-6E assigned to this port will be deactivated and cannot be utilized using that remote unit.

OPERATION

When a function is selected, pushing the RM-6E's corresponding onboard buttons will activate said function. In the case of "Gain Control", the up/down arrow buttons are used to adjust the gain as needed. When a "Mute" function is selected, simply pushing the button will mute the selected channel/source. Finally, when the Matrix function is selected, pushing the corresponding button will route the signal selected to the mix selected. Pushing it again will un-route the signal.

With up to 8 individual RM-6E units you're able to set a maximum of 48 individual gain controls, channel mutes and/or matrix routing presets for use at any time.

SIGNAL PROCESSORS

Below you will find the onboard signal processors of the DMP808 and information on their use and respective parameter. These can be applied to any of the 8 input or 8 output channels of the DMP808.

Compressor-Limiter

Compressor Threshold: Use this control to set the threshold of the compressor function. Any signals that surpass the selected threshold will be compressed at the selected ratio.

Compressor Attack: This control adjusts the attack time of the compressor, essentially determining the time taken for the compressor to kick in after it passes the selected threshold.

Ratio: This control can be used to set the ratio for the compressor. The ratio is expressed as :

.

Compressor Release: The release control determines the time the DMP808 will wait before disengaging the compressor when the signal bypasses the selected threshold.

Limiter Threshold: This control determines the threshold for the limiter function. This means that no signal will surpass the selected threshold, being 'compressed' at a ratio of infinity:1.

Output Gain: This control determines the amount of gain applied to the signal after already passing through the compressor-limiter.

On & Reset Buttons: The on button is, of course, used to turn the Compressor-Limiter on and off, while the reset button will reset all values to default.

Gate

On: This button turns the gate on and off.

Reset: Push the reset button to restore all parameters back to default.

Dynamic Graph: This graph shows the currently set gate properties and how it will affect your audio.

Level Meters: These meters give the input and output level of the gate for the current channel.

Gain Reduction: The gain reduction meter will provide a real-time indication of any reduction in signal caused by the gate.

Threshold: This control will set the threshold of the gate function. Any signals that fall below the set threshold will activate the gate function.

Range: This control sets the amount of attenuation when the gate is closed.

Attack: This control adjusts the attack time of the gate. This is the time the DMP808 will wait after the signal drops below the threshold before engaging the gate.

Hold: The hold will allow you to select the length of time the gate will remain open after the signal drops below the set threshold.

Release: The release control determines how long the gate will wait before disengaging when the signal rises back above the selected threshold.

Expander

On: This button turns the expander on and off.

Reset: Push the reset button to restore all parameters back to default.

Dynamic Graph: This graph shows the currently set expander properties and how it will affect your audio.

Level Meters: These meters give the input and output level of the expander for the current channel.

Gain Reduction: The gain reduction meter will provide a real-time indication of any reduction in signal caused by the expander.

Threshold: This control will set the threshold of the expander function. Any signals that fall below the set threshold will activate the expander at the user-set ratio.

Ratio: This signal sets the ratio of the expander function. When a signal drops below the threshold, the signal will be decreased by the selected ratio.

Attack: This control adjusts the attack time of the gate. This is the time the DMP808 will wait after the signal drops below the threshold before engaging the gate.

Release: The release control determines how long the gate will wait before disengaging when the signal rises back above the selected threshold.

Delay

Adding a delay on output can be particularly helpful to help time align drivers within a single cabinet or help avoid delay in larger multi speaker setups. For example, when there are a number of drivers in a single cabinet, typically they're different distances from the front of the cabinet.

The tweeter, typically longer than the woofer, could have its driver 8 inches deeper than the woofer. The problem this creates is the sound from the woofer will be pushed out a fraction of a second before the tweeter, arriving at the wavefront at different times. Adding a 0.6 millisecond delay to the woofer can combat this, essentially making the signal wait for the tweeter to catch up.

Delay: Use this control to adjust the delay time. To the right of the control, the selected delay will be indicated in milliseconds, meters and feet.

Temperature Control: This allows you to set the current temperature for the delay circuit. This allows the DMP808 to better refine the delay's 'meter' and 'feet' results. The temperature is indicated in both degrees Celsius and degrees Fahrenheit.

On & Reset Buttons: The on button is used to turn the delay circuit on and off. The reset button resets all values to default.

Parametric Equalizers

EQ On/Off Button: This button can turn the Equalizer for the currently selected channel on and off.

Reset: Push the reset button to restore all parameters back to default.

EQ Band On/Off: Use these buttons to turn the corresponding EQ bands on and off. While not named specifically, these bands can be thought of as the low, low-mid, high-mid and high frequency bands on your average 4-band EQ.

EQ Type: For the first and fourth bands on the EQ, users can select the type of curve used for the EQ. Band 1 can be swapped between a normal EQ band (PEAK), low shelf filter (SHELF), and high pass filter (CUT). Band 4 can be selected between an EQ band (PEAK), high shelf filter (SHELF), and low pass filter (CUT). The Low/High Pass Filters will cut frequencies above and below the selected frequencies at 18 dB per octave. High and Low Shelf filters act similarly, but cut frequencies below the selected frequency by the preset level determined by the user.

EQ Parameters: The EQ offers users the ability to view or edit various parameters/properties of their EQ bands, including the Gain (dB), the frequency (Hz/kHz) and the 'Q' of the EQ band.

Meters: Both input and output meters are available for this process, essentially showing the difference in the overall signal level after equalization.

Feedback Silencer

Feedback occurs when the sound from your speakers makes its way back into the mixer through microphones. The audio look causes a high pitch squeal or screech that can easily ruin your performance. Feedback can be removed, however, by reducing or removing the problem

TROUBLESHOOTING

I don't have any output

Have you activated the output channels? Do you see a signal in the output meters? Have you correctly routed your inputs to channels, turned levels up, and unmuted mixes? Have you applied an excessive compressor-limiter to any input or output signals?

I have a signal, but it's really distorted!

Are any of the Clip LEDs lighting up for input or output mixes? Do any of the signals on your entire audio chain seem excessive? This could include input connectors, channel inputs, matrix outputs.

My devices are not communicating via Ethernet

Are the red and green LEDs on the Ethernet connectors lighting up? Are you using a decent quality Ethernet cable?

My DMP808 won't communicate with my computer

Are you using a decent quality Ethernet cable? Are your computer and DMP808 both connected to the same network? Do you have a firewall turned on?

frequencies. With a razor-thin filter, feedback can be completely removed without affecting your audio what-so-ever.

The DMP808 features a 12 filter feedback silencer. This can operate in 2 different modes: Automatic and Manual. When set to automatic, the activated filters will automatically search for and remove feedback. When set to manual, the user is able to adjust the frequency, gain and Q of the individual filters.

Parameters: When the Feedback Silencer is set to "Manual" it offers users the ability to view or edit various parameters/properties of their EQ bands, including the Gain (dB), the frequency (Hz/kHz) and the 'Q' of the 12 filters.

Threshold: Adjusting the threshold will determine the level of signal required for the automatic feedback silencer to kick in.

31-band GEQ

Graphic equalizers are fantastic in live setups where you may need to compensate for room acoustics or other factors. Include a 31-band graphic equalizer on your speaker output signals to better refine your live audio.

Frequency bands: The GEQ's frequency bands can be boost or cut by the user. Frequencies are set at fixed frequencies between 20Hz and 20kHz.

How can I use the RS-232 port?

An RS-232 connection is available on the DMP808 to allow control information to be sent to the unit without the need of Ethernet connection. Asystems has provided an implementation reference on the website.

Initializing the DMP808

The DMP808 can be initialized using the DIP switch on the rear of the device. The left-most pin will allow users to begin initializing the unit. It can be returned to the RESUME position to continue operation.

Why are the front panel VRs not working?

The rear panel has a DIP switch that controls these VRs. If set to the lower position these will be locked and you will be unable to use them.
