AUDIO OUTPUT
SPEAKER OUTPUTS
Every two output channels (one odd channel and the
next even channel) can be bridged into one channel,
through which, please note; that a bridged channel, has
twice more power as an unbridged channel, because the
bridged channel has two channels combined.)
To bridge channels, just wire the “+” pin of an odd
channel to the “+” pin of the next even channel. When
bridged, the “+” pin of the even channel; becomes the “-”
pin of the bridged new output.

of events to occur at a particular time of day� Events can range from simply powering on and off the device to
activating audio les 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 DMA amplier provided power is supplied to the device, whether active or in standby mode.

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 lter can also be
added to each of the analog inputs to help remove stage
rumble and other unwanted noise.
14
Global In On/Off
This menu provides each individual button input, including the analog inputs, network inputs, AES/EBU inputs 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 DMA.
Source: This is used to select the source of the duck function; i.e. 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 predened 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.
15
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�
COMP - 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 innity: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
<input>:<output>.
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 DMA will wait before disengaging the compressor when the signal bypasses the selected threshold.
Side Chain HPF: This allows users to set a high pass lter 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 DMA 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 conrm.
Power Settings: There are three power settings on
the DMA.The software power can be turned on and off, essentially enabling the DMA 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 DMA�
Relay (GPIO)
The GPI – or General Purpose Interface – output is used
to remotely control the Asystems DMA� The relay page
itself is used to setup the GPIs, including any and all
remote controls connected to the unit�
The Preset panel is for use with the RM-4 remote preset controllers. The numbers in the “Port” eld correspond with the ports on the rear of the DMA amplier. The “No” eld is the “Scene” number found in the utility tab. Any of your pre-saved scenes can be assigned to the available
ports�
16
RM Control
This page offers a number of assignment options for the optional Asystems RM remote controls, specically the RM-6E. More detailed information on this will be available within the RM-6E operating guide.
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 nd their
own settings and save them for later use� The DMA has
onboard storage for a number of settings to be saved, or users can conn ect USB ash drives to save settings. Also available in the Utility menu is a rmware update button. When a new version of rmware is available it can be installed using the “Update” button. Place the rmware update le on a formatted USB ash drive and insert it into a USB port. The “Update” button should take care of the rest. After the rmware is updated, the initialize button can be selected to reset the device. Save any settings (or “scenes”) before initializing the system.
Protect
The protect menu gives real-time updates on the system
performance� Everything from the system temperature to the output wattage is represented on this page� If the
Protect LED on the front of the DMA amplier lights up, this menu can be viewed to better understand the issue.
