Output AGC (Automatic Gain Control)
AGC is enabled by default on all outputs. AGC is independent of IGC (Intelligent Gain Control) on
each input.
AGC is triggered if mixed audio signals approach -2dBFS.This is to prevent hard clipping, which
would introduce excessive distortion when the summed input signals exceed the full-scale range.
AGC has a very fast reaction time and will decrease high audio levels by approximately 1dB every
few milliseconds, up to a maximum of 34 dB of attenuation. AGC tries to return levels to normal
once the output dips below -7dBFs. This will gradually increase the levels by approximately 1dB
after a predetermined time-frame measured in milliseconds. To enable or disable AGC:
1. Press the HOME
2. Tap General
3. Tap the On/Off button to toggle AGC on and off.
