Controls the level of the signal being sent to the AUX bus. The level being sent to the Aux bus
will also be affected if the gain control in that channel is changed.
This control sets the input gain in each channel. The amount of gain is adjustable from +25
dB to +60 dB. (Mic input.)
In the automatic mode the LED will glow green, indicating the channel that is predominant
in the mix (auto mode). If the channel is in the manual mode the LED will stay on if the front
panel level control is at or above the 12:00 position. The green LED is also an indication of
the status output state. If the LED is on, then the status output will be high (+5 volts). If the
LED is off, then the status output will be low (0 volts).
CLIPPING
The LED will turn red if the channel is within 1 dB of clipping.
Turning the priority control clockwise allows one channel to override the others in the mix.
It does this by "tricking" the gain computing circuits into thinking this channel is louder
than the others. Up to 9 dB of priority is available.
This control sets the level of the signal being sent to the Aux Out. This level should be set
after the individual channel levels have been set.
The downward expander can be used to attenuate the system gain when all of the input
signals are low. This can be used to prevent background room noise from being amplified.
SETTING THE DOWNWARD EXPANDER
Have someone speak into a microphone at the softest level you can expect to encounter.
Slowly turn the downward expander clockwise until the background noise between words
is attenuated. Be careful not to go too far. The more downward expander that is used, the
less "natural" sounding the system will become. This method will give you a good starting
point, but the best way to set the downward expander is during an actual meeting or event.
While doing this, the downward expander can be adjusted for the best sound. If you have to
deal with both loud and quiet events, you will need to trade off between natural sounding
ambient and background noise.
This control sets the maximum overall system gain and should be set with the front panel
master gain set to the full clockwise position, all channels at unity, and external power
amps turned up and locked at operational settings. When trimmed to a safe margin below
feedback, no combination of user controls can cause feedback. This trim provides up to 25
dB of attenuation of the system gain.
The notch filter level control adjusts the amount of cut at the frequency selected by the
corresponding frequency control (12). It is adjustable from 0 dB to 15 dB of cut.
