14
DMA8825 / DMA8813 / DMA8425 / DMA8413
English
Global In On/O
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 predened 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 aected, 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�
15
DMA8825 / DMA8813 / DMA8425 / DMA8413
English
LIM/COMP - Limiter/Compressor
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 innity: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 conrm.
Power Settings: There are three power settings on the
DMA. The software power can be turned on and o,
essentially enabling the DMA to be turned on and o via
the software – including event scheduling� The hardware
power can be selected on and o, 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 DMA digital matrix amplier. 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 amplier. 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
DMA8825 / DMA8813 / DMA8425 / DMA8413
English
RM Control
This page oers a number of assignment options for the
Asystems RM remote controls, specically the RM-6E
(sold separately). Each of the “Keys” listed in this page
will correspond with a button on the RM-6E. Beside each
key users will be able to select the function. This may be
gain control, input/output mute, matrix mixing, etc. The
last eld will allow users to select a ‘source’ related to
their selected function. For example, if “Gain Control” is
selected, users will be able to select which input channel’s
gain is adjusted when that key is selected on the remote.
Up to 8 RM-6E remotes can be used at any one time.
Each should be set to a dierent port to help identify it.
Individual remotes can be locked using the corresponding
buttons within the RM Control menu. Port settings for the
RM-6E can be found on page 8.
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 connect 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 amplier lights up,
this menu can be viewed to better understand the issue.
