Pre Gain Meter
The Pre Gain meter displays the mic input level before gain adjustments. Meter range is determined by the Coarse
Gain Slider in the Gain section of the screen as described below.
NOTE: All meters in Console are peak-level meters.
Gain Section
The Coarse and Fine gain sliders are used to match the level settings between mic inputs, and to adjust the
volume level for a given mic input channel. The Min/Max fine gain sliders are used to set minimum and maximum
gain settings, and to report min/max gain settings via serial commands.
In general, you should set the Coarse gain slider to 56dB for a mic input, 28dB for active equipment that requires
an input between mic and line level, or 0dB for a line level input device.
Use the Fine gain slider to adjust input volume level. You can also set fine gain in .5dB increments using the Up/
Down buttons, or enter a value directly in the field.
Post Gain Meter
The Post Gain Meter displays the audio level after gain adjustments.
Post Process Meter
The Post Process Meter displays the audio level after it passes through all mic input processing, such as Processing
channels, Filters, AEC, NC, AGC/ALC, and Mute.
