Beep Configuration
Configures a beep mixed with the HP and Line output.
Notes:
1.
When used in analog pass through mode, the output alternates between the signal from the PGA and
the beep signal. The beep signal does not mix with the analog signal from the PGA.
2.
Re-engaging the beep before it has completed its initial cycle will cause the beep signal to remain ON
for the maximum ONTIME duration.
