Adjusting the Input Gain (Sensitivity)
Here’s how to adjust the input gain so that the AUDIO IN 1 or 2 audio is at the appropriate level.
1 . Move the AUDIO INPUT LEVEL [1] or [2] knob to a position
near “0dB.”
2 . Move the [ MASTER OUTPUT ] knob to a position near “0 dB.”

“AUDIO IN 2”
Ó
“ANALOG GAIN,” and press the [VALUE]
knob.
4 . Turn the [VALUE] knob fully counter-clockwise,
minimizing (0dB) the input gain.
5 . While producing the sound that will actually be input,
slowly turn the [VALUE] knob clockwise to adjust the
input gain.
Raise the input gain as high as possible without allowing the SIG/
PEAK indicator of AUDIO INPUT LEVEL 1 or 2 to light red when the
loudest sound level occurs.
6 . Press the [MENU] button to close the menu.

setting on/off, phantom power automatically turns off.
Adjusting the mic position (pan)
The left/right positioning of the sound is called “pan.” If you’re
using two mics to stream a performance, panning the two mics
to left and right will give the sound a more spacious feel.

SIG/PEAK indicator
Indicator Status
Red
Volume is excessive (0 dB or higher)
Yellow Volume is appropriate (-20 – -1 dB).
Green Volume is insufficient (-50– -21 dB).
Adjusting the digital gain
You can adjust the digital gain for all inputs. Analog gain adjusts
the analog sound, and digital gain adjusts the digital sound.
When a high-level audio signal is input to the HDMI or SDI digital
audio inputs, distortion may occur due to effect processing.
You can use digital gain to keep the input level down so that
there is no impact on effect processing.
