Changing the input gain and attenuation
Users can set the level of audio gain or attenuation (-18 dB to +24 dB) of each input from
the I/O Settings page. Audio levels can be adjusted so there are no noticeable volume
differences between sources.
Change the gain and attenuation setting for an input as follows:
1. Click the Input Audio Level drop box for the desired input. A drop-down scroll box
appears (figure 74).

2. Click and drag the slider or click on the scroll up button or the scroll down button
until the desired value is visible and then click that value.
NOTE: As an alternative to steps 1 and 2, listen to the audio as you make
adjustments by clicking the up button and down buttons.
