Intercom Operation

Intercom Operation
2.10.
Intercom operation may be triggered automatically via VOX (with adjustable
threshold) or externally via intercom switch.
The setting of VOX-threshold and intercom volume is accessible in the pilot
intercom menu, in tandem configuration on primary controller only.
For a single block, the primary controller is the one directly connected to
VHF transmitter. For a remote VHF transmitter the primary controller is the
one connected to primary control interface.
VOX-threshold and intercom volume for the second intercom circuit are
controllable from secondary controller RCU6201 (secondary controller is
the one connected to secondary control interface).
The transceiver has two internal built in intercom circuits. Therefore, up to
four headsets are connectable. Pilot and co-pilot connect to the first
intercom circuit. When intercom is active, both microphone signals are
mixed and amplified with each other and will be audible on both headphone
outputs. This enables internal communication via headsets between both
pilots. Passenger headsets are connecting to the second intercom circuit.
ALL mode - Everyone connected to the intercom will hear all
communications (pilots hear passengers and passengers hear pilots).
ISOL mode - Provides separate intercoms for the pilots (intercom circuit
one) and the passengers (intercom circuit two). This allows pilots to
communicate with each other, and air traffic, while the passengers are
isolated. The passengers on the intercom circuit two can hear auxiliary
audio (for example from mp3 player) and can communicate with each
other.
External "ISOL" input provides possibility to switch between ALL mode and
ISOL mode. If the /PTT1 input is active and ISOL is active the passenger
intercom operation on second intercom circuit is still possible.
While transmit mode intercom operation is degraded. During receive mode
the intercom operation activates automatically via VOX (with adjustable
threshold), or using the external intercom switch.
If intercom operation is active, the "IC" sign appears in the display.
