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-dened threshold by a user-dened 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 specic 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 lter will cut or
signicantly reduce all audio signals below a particular

CONTROLS & SETTINGS
FRONT PANEL
1. Mounting Holes
These holes are for mounting the DMP808 on a standard
19” rack�
2. Power Switch
Flick this switch to sturn the unit on or put it on standy� Be
aware that the power switch can be disabled through the
A Systems DMP808 software�
3. Power LED
This LED indicator will illuminate when the DMP808
is activated – whether by switch or through the remote
software�
4. Disable LED
This LED will light up when the power switch is disabled�
When this occurs, the DMP808 cannot be turned on or
put on standby via the front panel switch� This function is
disabled within the A Systems PC software�
5. Output LEDs
The Mix Output LEDs will light up green when an output
signal is present on the corresponding output mix� It will
also ash red when the output channel clips. In this event,
you can reduce any excessive input signals, or turn down
your master output mix level through the control software�
6. Signal/Clip LED
This LED indicator is found on every input channel� When
a signal is present in the input channel, the LED will light
up green� When it clips, it will light up red� In the event that
the LED is red, we suggest reducing the input signal level�
Occasional ashes may be acceptable if it doesn’t affect
your program material�
7. Gain Controls
These rotary controls will allow users to adjust the nal
input level for channels 1 through 8�
user-dened frequency, allowing – as the name suggests
– high frequency sounds to pass through�
High Shelf Filter – the high shelf lter 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 innity-to-1.
LPF – Low Pass Filter – a low pass lter will cut all
audio signals above a particular user-dened frequency,
allowing low frequency sounds to pass through� This is
signicantly 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 signicantly attenuates the audio signal
passing through it when the signal level falls below a user
adjustable threshold�
UnbalancedConnections– unlikebalancedconnections,
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�

English
DMP808
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 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�
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�

14
English
DMP808
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
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 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
lter 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 networing
feature. The ENTER button must be pushed to conrm.
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-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.
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�
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�

DMP808
Below you will nd 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 <input>:<output>�
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 innity: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�
SIGNAL PROCESSORS
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 rene 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�
