Programmable XM Radio tuner with XM
channel data display
The unit also accepts signals from line, telephone,
or microphone (phantom power included). The
priority ducking feature drops the volume of the
background music when a microphone is used.
A VOX sensitivity setting controls how loud the
voice must be before ducking occurs.
Input Sensitivity (for full output at maximum
gain):
