mixer seems unexpectedly low, check the setting of the Windows Mixer WAVE con-

changed it.

your computer's operating system requirements. Instead, use the controls in
OPTIMOD-PC's I/O Mixer to set the level applied to applications receiving WAVE
data.
Input Setup Procedure
1. Adjust the Analog Input Reference Level control.

The input stage has 20dB of headroom prior to the Input Level Control.
Hence, a +4dBu tone at the analog input indicates –20dB on the analog
