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