In Figure 64, the Audio Level control is different depending on which input is selected.
The Input Reference level is meaningful only on the analog unbalanced and balanced inputs, and is
calibrated differently for each when a digital input is selected this control is disabled. This is a
hardware gain control with the default level chosen such that the expected amplitude of a full
volume input signal will have adequate headroom without clipping. If you do experience clipping, or
are working with low-level signals, you can adjust this level. On this control, a higher reference level
results in lower gain, so the quietest setting is at the top of the scale. Click Default to restore the
default value.

The Boost setting is a software gain adjustment that applies to both analog and digital inputs. Boost
can be set individually for each input. It supplements the system mixer volume controls by providing
a wide adjustment range. You can use it to calibrate or normalize input levels across multiple inputs;
or to accommodate microphones or other non-line inputs that have nonstandard signal levels.
Again, the Default button restores the default value.
