level for the pilot and copilot, while the outer knob controls the passenger intercom volume. Intercom
squelch is automatic.
An “Alternate Intercom Mode” is incorporated in
the PMA7000BT. This allows the passengers and crew to
converse, but removes radio traffic from the passengers’ headphones, and blocks passenger mics from the
crew during radio receptions.
A Bluetooth® module is included that adds music (as Music 1) connectivity as well as telephone interface
with Bluetooth-enabled smart phones.
A 3-light Marker Beacon receiver is integrated in the PMA7000BT. This provides the necessary Marker
Beacon lights and audio indications necessary for an Instrument Landing System (ILS) approach.
