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
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�

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�

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�
