INTRODUCTION
Congratulations on your purchase of the DMP8800 digital
matrix processor� The DMP8800’s modular expansion
cards will provide you with up to eight channels of audio
matrixing and processing� A single DMP processor
offers eight-in, eight-out support and the entire unit can
be controlled remotely via 10/100 Ethernet, standard
potentiometers and remote controls� Internal processing
is accomplished through a high quality 40-bit oating
point processor, with internal signal processors and
matrix routing all handled with ease�
DMP digital matrix processors offer easy, effective means
for injecting signal processors directly into your input
and output path, with clear, easy-to-use software both
onboard and on your Windows computer� The software
offers full performance monitoring for each processor,
giving real-time information on the load placed upon
DSPs�
We know how eager you are to get started – hooking up
your new DMP processor is probably your rst priority
right now – but we would advise that you take the time
to look over this manual. Inside you’ll nd important
safety considerations and operating instructions that
could prove helpful� After reading the manual, we would
suggest putting it somewhere easy to nd as you will
probably need to refer to it later on�
FEATURES
√ 8 input channels available via 3-pin euroblock
connections and paired RCA inputs
√ VGA and USB connectors enable use as a self-
contained system
√ 40-bit floating point processor with internal
sampling selectable between 44�1 and 48 kHz

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 RCAinput 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-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�

3
DMP8800
English
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 lter will cut or
signicantly reduce all audio signals below a particular
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�
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 exible 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 signicantly 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�

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 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�
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 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
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

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
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 nd 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 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

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 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�
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
specically, these bands can be thought of as the low,
low-mid, high-mid and high frequency bands on your
average 4-band EQ.

13
DMP8800
English
EQ Type: For the rst 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 lter (SHELF), and high pass lter (CUT). Band
4 can be selected between an EQ band (PEAK), high
shelf lter (SHELF), and low pass lter (CUT). The Low/
High Pass Filters will cut frequencies above and below
the selected frequencies at 18 dB per octave� High and
Low Shelf lters 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 lter, feedback can be
completely removed without affecting your audio what-
so-ever�
The DMP8800 features a 12 lter feedback silencer.
This can operate in 2 different modes: Automatic and
Manual. When set to automatic, the activated lters 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 lters.
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
lters.
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 rene your live audio.
Frequency bands: The GEQ’s frequency bands can be
boost or cut by the user. Frequencies are set at xed
frequencies between 20Hz and 20kHz�
Q: The Q for the individual bands of the 31-band GEQ
can be adjusted to better rene the equalization.
VCA
VCA – or voltage controlled amplier – 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).
