PS-8810
DIGITAL SIGNAL PROCESSOR
NOM (Number of Open Mics) Attenuation reduces overall system
gain as the number of open mics increases beyond one for
improved gain before feedback.
There are three group controls for this feature:
Enable
Turns NOM Attenuation on and off within an automix group
Mode
Sets the attenuation algorithm to linear or logarithmic. In linear
mode, each open mic beyond one will cause all inputs in the
auto-mix group to be attenuated by an amount equal to the
Attenuation Step Size, defined below.
logarithmic mode: the attenuation per open mic will decrease as
more mics open. Logarithmic mode with Attenuation Step Size
of 3dB emulates 'classic' NOM attenuation schemes
Linear mode: allows each individual mic to use a higher nominal
gain by more aggressively attenuating as more mics open.
Step Size
With NOM Attenuation mode, determines the attenuation as a
function of the number of open mics in the auto-mix group. In
linear mode, each open mic beyond one increases the
attenuation by this amount.
Control range is from 0.5 to 3dB in 0.5dB steps.
Adaptive Gating dynamically modifies the Input Gate thresholds in
the auto-mix group as a function of the ambient level in the room.
The ambient level is computed as the weighted average of the
closed mic input levels. The weighted average makes it possible to
compensate for mic locations with different ambient levels.
There are two group controls, one group meter, and one
individual input control for this feature:
