GETTING STARTED

For easy control of the DMP processor, simply connect a VGA monitor and USB mouse to the VGA and USB connectors on the rear of the device. This will give you immediate access to the onboard software without the need of a computer.

Using the Mouse: To operate the onboard software with a connected mouse, simply point and click as you would on a computer. When adjusting virtual rotary controls, you are able to click either the right or left mouse buttons to increase and decrease the setting, respectively.

The DMP processors can also be connected to your local area network and controlled via network or internet software. By installing the Asystems software on a computer will allow for remote control of this unit. Enter the DMP8800's IP address into the PC software to locate the DMP on either the local area network – or anywhere on the internet, provided both the computer and DMP are online.

Connect all necessary input and output devices. Input can be achieved through either the RCA input connectors, or with correctly wired euroblock connectors. Wiring for balanced euroblock connectors should be as follows:

Pin 1: Shield/Ground

Pin 2: Cold (−)

Pin 3: Hot (+)

Whereas unbalanced connectors can be wired as so:

Pin 1: Shield/Ground

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.

CONTROLS & SETTINGS

FRONT PANEL

1. Mounting Holes

These holes are for mounting the DMP8800 matrix processor on a standard 19" rack.

2. Power Switch

Flick this switch to turn the unit on or put it in standby mode. Be aware that the power switch can be disabled through the Asystems DMP8800 software.

3. Standby LED

This LED indicator allows the user to see when the unit is in standby mode. This essentially shows when the DMP8800 is disabled.

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 software that is featured within the DMP8800, visible through a VGA monitor.

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.

Matrix - this is a complex way of routing signals, where actual input signals can be assigned to virtual input channels, each of which can then be routed to any number of outputs. With numerous output options, the inputs can be assigned to any or all, if required, making routing far more flexible than normal mixing.

Network – as the name suggests, a networked audio system is simply a set of audio devices connected together in a chain. This allows the units to share input and output signals.

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.

4. Power Disable LED

This LED indicator will show when the power switch of the DMP8800 has been disabled by the Asystems software. When the Power Disable LED lights up red, the DMP8800 can only be activated or deactivated using the Asystems software.

5. Clock Source

These LEDs will indicate the currently selected clock source between Internal, Network, AES/EBU and Word Clock. The master clock source is selected within the Asystems software. The Network clock LED turns orange to indicate Net Matrix Mode.

6. Sample Rate

The internal sampling rate of the DMP8800 is selectable between 44.1 and 48 kHz. These indicators will light up with the currently selected sampling rate.

7. Level Meters

These meters allow users to view the output signal levels. There are four LEDs in total, the top of which indicates whether the output signal is clipping.

8. Meter Button & Input LED

Pushing this button will change the status of the level meter between that of a pre-DSP input signal level meter and an output level meter.

9. Phantom Power LEDs

These LED indicators will light up when the corresponding input's phantom power circuit is activated. Phantom power itself can be turned on using the Asystems software.

10. Remote Enable LEDs

When a remote level control is connected and active for the corresponding channel, this LED will indicate as such.

11. Enable LEDs

This LED will light up when the corresponding channel is activated. This is done through the DMP8800 software.

12. Gain Controls

These rotary controls will allow users to adjust the final input level for channels 1 through 8.

REAR PANEL

13. Ethernet Connection

This connection is for standard RJ-45 cables, used for 10/100 Ethernet control. Using a CAT5 twisted pair copper cable, Asystems doesn't recommend a distance of more than 100 meters to the nearest computer or hub. The Ethernet connection is used to control the software via the PC control software and the RM-6E programmable remote controls.

14. Euroblock Line Inputs

The DMP8800 offers a total of eight line input channels. These inputs are active balanced with euroblock connectors. If an unbalanced signal is used, Asystems advises that customers ground the unused conductor.

15 RCA Line Inputs

These unbalanced RCA connectors are for the connection of stereo RCA cables. They accompany each of the eight line input channels mentioned previously. The stereo signals these inputs receive are summed to create a mono mix.

16. Line Outputs

The DMP8800 offers a total of eight line outputs. These are servo-balanced euroblock connectors and can be wired to either balanced or unbalanced connections.

17. Peripheral Connector

This RJ-45 connector is for connecting Asystems remote peripherals to the DMP8800 series processor.

18. USB Connectors

Two USB connectors have been included on the DMP8800 for use with a USB mouse – either wired or wireless – and USB flash drives. A USB mouse can be used to control the internal software without the need of a computer. The flash drive can be connected when performing firmware updates.

19. VGA Connector

This is a standard XVGA connector for use with standard computer monitors and high definition displays. This will allow you to control the internal software of the DMP8800 without the need of a computer.

20. RS232 Interface

Standard RS232 interface is provided to facilitate third-party external control system operation of the DMP8800.

21. Word Clock

Word clock connections essentially help keep your gear in sync. If two digital audio devices have different sampling rates, there could be sample skipping, jittering, delays and other unwanted anomalies in your digital afudio. Word clock synchronization is imperative to keep them at the same sampling rates and ensure this does not occur. When, for example, using several AES/EBU devices in a chain, a master word clock connected to each device will help them become perfectly synchronized.

22. AES/EBU Connectors

These connectors are for digital devices with AES/EBU inputs and outputs.

23. SD Card Slot

Insert an SD card into this slot to integrate MP3 files into your mix.

24. Preset Recall

These connectors are compatible with the Asystems RM-4 remote controls. See the Remote Control section of this manual for wiring instructions.

25 Remote Level Control

These euroblock connections can be wired to connect the Asystems RM-2VR remote level controls. Each RM-2VR allows for two channels to have their levels controlled.

26. Digital I/O Expansion Card Slot

For installing Asystems DT22/DT44/DT88 Dante Networking card to enable DMP devices as a networking portal to other audio devices.

27. AC Power Connector

This is for a standard IEC power cable.

DMP MATRIX SOFTWARE

Firmware

Before beginning, it's a good idea to ensure you've installed the latest firmware. The latest firmware can always be found on www.asystems-sys.com. Place the firmware update file onto a FAT-32 formatted USB memory stick and connect it to one of the DMP8800's rear-panel USB slots. Open the DMP8800's internal software then enter the Utility menu. At the bottom of this menu is the firmware update function. Push the "Update" button to perform a firmware update.

Connection

For a connection to be established between the Asystems remote software and the DMP8800, first both need to be connected to the same local area network or be 'online' (ie. on the internet). Opening the Network settings menu in the DMP8800's onboard software will allow users to view or edit properties such as IP address. On a local area network, this will be shown 192.168.x.x (where x is dependent on your network). After setting the unit's IP address, this can be entered into the Aystems remote software's setup section to locate the DMP8800. A user name and password can be set to protect the unit from unauthorized control.

Metering

The front panel of the DMP8800 offers 8 level meters for monitoring input and output signals. These meters also include clip indicators to show when signals are so excessive as to clip the signal. For additional metering of individual signals and mixes, the matrix pages of the DMP8800 software can be consulted.

Remote Gain Controls: The control panel menu offers a remote gain control for each channel. The gain control indicates that set by a remote level control and can be edited using the DMP8800's software.

GAIN ON: All remote gain controls can be deactivated using these buttons.

Total Att.: This section will indicate the total amount of attenuation applied to an input signal, expressed in decibels.

Network

When using the DMP8800 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.

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

DHCP Server/Client: Users can activate DHCP – Dynamic Host Configuration Protocol – on the DMP8800. The DMP8800 can be selected as either a client or a server. When your local network runs off a DHCP protocol, the network will automatically assign your DMP8800 an IP address. If your network runs off a DHCP server, you can turn it on using the DHCP Client button. If you wish to set your DMP8800 as the DHCP server, turn it on here.

IP Address: When not using a DHCP server, you can enter an IP address for your DMP8800 here. Otherwise it will be automatically assigned. If entering your own IP address, Asystems suggests 192.168.x.99 – where "x" could be determined by your local area network's settings. Check network settings on other computers on the same network for this value.

Subnet Mask: The subnet mask for your DMP8800 can be entered into this field. For most networks – and particularly if you're unsure what it is – this should be kept set as "255.255.255.0".

Gateway Address: A gateway is a device that can connect other devices in a network that use different types of protocols. This is typically your router, but a computer could also serve as a gateway.

Current Users: At the bottom of the page, a list of currently connected users will be displayed. This list will include the user name, the IP address of the user and the level of access they're afforded.

Security

This tab can be found under the Network Settings menu. The security tab provides a means of securing the DMP8800 against unauthorized or unqualified changes. Through the DMP8800's onboard software these accounts can be created for use of the Asystems remote software.

Events

In the Events menu you will be able to set up a number of events to occur at a particular time of day. Events can range from simply powering on and off the device to activating audio files at a particular time.

Current Time & Current Date: Here users can set the current date and time. Click the Save button to set these settings. The date and time will be maintained within the DMP processor provided power is supplied to the device, whether active or in standby mode.

Time Format: Set the time format to AM/PM or 24 Hour time.

Schedule: Any already set Events will be displayed here. Number: Assign a number to the event you're currently setting.

Subject: Provide a name or description to your event.

Location: Describe the location of where the event will occur.

Type: Select the type of event you are setting here. Available types include power change, channel mute and relay.

Action: The action can be selected between on and standby.

Date: Set the date to begin your event.

Time: Set the time the event should occur, down to the very second.

Period: In the period section you will be able to set whether to set your event to occur once, weekly, daily, etc. You can also pick the days of the week for it to occur.

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 on buttons for each individual input including the analog inputs, network inputs, AES/EBU 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 DMP8800.

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 channel outputs, network outputs or AES/EBU outputs.

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 DMP8800 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 a master clock source for digital devices. Selecting 44.1 or 48 kHz will set the DMP8800 as the master clock source and determine the sampling rate. Selecting AES/EBU, Network, or Word Clock will set these as the master clock. Whenever a new clock source is selected, the ENTER button must be pushed to confirm.

Power Settings: There are three power settings on the DMP8800. The software power can be turned on and off, essentially enabling the DMP8800 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 DMP8800.

Relay (GPIO)

The GPI – or General Purpose Interface – output is used to remotely control the Asystems DMP8800. The relay page itself is used to setup the GPIs, including any and all remote controls connected to the unit. More detailed information on this will be provided at a later date.

RM Control

This page offers a number of assignment options for the optional Asystems RM remote controls. More detailed information on this can be found later in this manual

Utility

All of the DSP processes can have their settings saved for later use. 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 DMP8800 has onboard storage for a number of settings to be saved, or users can connect USB flash drives to save settings. Also available in the Utility menu is a firmware update button. When a new version of firmware is available it can be installed using the "Update" button. Place the firmware update file on a formatted USB flash drive and insert it into a USB port. The "Update" button should take care of the rest. After the firmware is updated, the initialize button can be selected to reset the device. Save any settings (or "scenes") before initializing the system.

SIGNAL PROCESSORS

Below you will find the onboard signal processors of the DMP8800 and information on their use and respective parameter. These can be applied to any of the input or output channels of the DMP8800.

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 DMP8800 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 DMP8800 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 DMP8800 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 DMP8800 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 frequencies. With a razor-thin filter, feedback can be completely removed without affecting your audio what-so-ever.

The DMP8800 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.

Q: The Q for the individual bands of the 31-band GEQ can be adjusted to better refine the equalization.

VCA

VCA – or voltage controlled amplifier – allows for multiple mixes to be controlled together while still maintaining their respective offset. The VCA offers four groups for channels to be assigned where each of these individual groups can have their levels controlled together using the VCA faders. This is typically helpful in ensuring things such as vocals or instruments can be controlled without affecting the mix of audio.

Assign: When the VCA is selected for a channel on the DSP page, the channel's signal can be routed or assigned to one of four groups shown here. To assign the group, push the respective button and increase the respective rotary control. This will determine the level of the signal that will be sent to this VCA group.

Meter: These meters will show the input level of the channel as well as the appropriate output level when after the VCA has been applied.

On: Activating the on button will apply the VCA to the appropriate channel.

Fader: Pushing the fader button will bring up a new window that features a fader for each of the four VCA groups. Adjusting these faders will adjust channels in their respective VCA groups accordingly. As previously noted, adjusting a VCA group will still allow the channels to keep the offset between each channel. Each fader also features an on/off button that will activate and deactivate the VCA group.

Divider: I/O with HPF and LPF, 2 or 3-way divider (for output only).

With a single RM-2VR you will be able to control up to 2 channels of the DMP8800 Digital Matrix Processor at a single time. Up to four RM-2VRs can be utilized at any one time to control all 8 outputs.

SETUP AND OPERATION

To utilize the RM-2VR you will need to activate the remote within the DMP software. At the bottom of each channel within the "Control Panel" window you will be able to find an on/off button for the Remote level control. You will also be able to view the remote level in the virtual rotary control found directly below this button.

DMP8800

WIRING

The RM-2VR can be wired to the "Remote Level Control" section on the rear of the Asystems DMP8800 digital matrix processors.

As shown, there are pins for each of the devices' 8 input mixes in addition to a +5V power pin and a grounding pin. Each of the 8 pins corresponds with the output mix of the device you're using. This being the case, for a single RM-2VR to control channels 1 and 2, it should be wired thusly:

Channel 2 Ground is internally wired to channel 1 ground

Do not connect the RM-2VR grounding pins to any other external grounds.

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 DMP8800.

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 8800. 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 DMA and DMP 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 DMP or DMA unit.

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 DMA and DMP 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 DMA or DMP series device. 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.

TROUBLESHOOTING
