Mic/Line Input Gain

There are two mono mic/line input channels. Channel controls and processing blocks are identical for each input channel.

See the Optimizing Audio Levels section for more information.

Adjusting Mic/Line Input Gain

Each mono mic/line input channel GAIN block provides a single long-throw fader with a gain range of -18 dB to +60 dB and a level setting text field below the fader. You can adjust the level in 0.1 dB increments.

Mute is located post-fader, pre-meter, and post-ADC. A single Mute button provides control of channel muting. You can set the polarity to positive (+) or negative (-), with positive polarity being the default.

The gain range accommodates a line level signal, typically from line level source devices or a wireless microphone receiver with a line level output, or a mic level signal from dynamic or condenser microphones. Phantom power is provided for condenser mics that may require it.

A peak meter is located post-fader and post-ADC (analog to digital converter). The peak meter displays levels of -60 dBFS to 0 dBFS, with a last-peak-level (peak hold) readout below the meter. You can resize the Mic/Line Gain dialog box vertically to adjust the view of the fader. The default setting is unmuted at unity gain (0.0 dB).

To adjust the fader level:

  1. Click the fader handle or click within the fader area.

  2. Adjust the level using any of the following methods:

  3. Click and hold the fader handle, then drag it to the desired level in 0.1 dB increments.

  4. Press the <Up arrow> or <Down arrow> key to respectively increase or decrease the level in 1 dB increments.

  5. Press the <Page Up> or <Page Down> key to respectively increase or decrease the level in 10 dB increments.

  6. Click in the level text field (resolution is 0.1 dB increments) and enter a new value. Then, press <Enter> or press <Tab> to move to another area of the dialog box.

  1. Click OK to accept the changes and close the dialog box. Click Cancel to close the dialog box without saving any changes.
