Processing & Parameters

3.2 Automatic Gain Control (AGC)

Automatic Gain Control is a dynamics process which compensates for the differences in level
between varying music sources, thereby allowing you to effectively raise lower level music
material for a more consistent level.
AGC Parameters
The AGC algorithm contains the following parameters:
• AGC Enable - This parameter turns the AGC algorithm on or off.
• AGC Threshold (-80 dB - -50 dB) - The Threshold sets a lower limit to the AGC. This
prevents the AGC from adding gain to low level signals or when no signal is present.
• AGC Max Gain (1 dB - 20 dB) - This adjusts the maximum amount of gain that will be
added by the AGC algorithm.
• AGC Target (-40 dB - -1 dB) - The Target parameter defines where you would like
the average level of the AGC output to be. For signals with an average level below the
Target, the gain will be increased. If the average level of the signal rises above the
Target, the gain will be reduced.
• AGC Window (1 dB - +10 dB) - This parameter adjusts how much the output level is
allowed to wander from the set Target parameter.
• AGC Attack (1 sec - 9.9 sec) - This adjusts how fast the AGC will increase gain.
• AGC Release (10 dB/sec - 0 dB/sec) - This adjusts how fast the AGC will reduce gain.

3.3 Center Mix

Center Mix allows you to route the microphone or music to the center output channel or
provide a mix of the two signals.
Center Mix Parameters
Center Mix contains the following parameter:
• Center Mix (Mic, 1-99, Music) - Rotating the Adjust/Select knob all the way to the
left (Mic) will send only the mic signal to the center output channel. Rotating the
Adjust/Select knob all the way to the right (Mus) will send only the music signal to
the center output channel. Values between 1 and 99 will blend or mix the two signal
levels. Setting this parameter to 50 will yield a 100% mix of both microphone and
music.
