4.4.2 Music Mute Control
PMA9000EX controls the music muting allowing the user to tailor the
SoftMute™ to their taste and situation. There are two SoftMute™ mut-
ing circuits. The SoftMute™ circuit will cut the music almost com-
pletely out whenever there is conversation on the radio or intercom.
When that conversation stops, the music returns to the previous level
comfortably, over a second or so.
For those occasions when the music muting isn’t necessary or desired,
the SoftMute can be disabled from the front panel.
Push the small knob to highlight the cursor. Select the MUTE by
turning the small knob, and push the knob again to toggle mute
on or off. This mute control is for the Crew music only. Passenger
music muting is controlled through a switch installed in a location
convenient to the passengers.
