USB In Level parameter
Use the USB In Level parameter to adjust the
level of the incoming USB audio signal (such as
backing tracks).
This control has no effect if Input is set to USB
and you are post-processing the received signal
via a DAW. The track controls within the DAW it-
self will determine the output level (and therefore
the Play Acoustic USB input level).
USB Out Level parameter
Use the USB Out Level parameter to control the
level of the audio signal sent over USB.
If the device you are connected to is clipping at
its input, try turning this parameter down.
