Auxiliary Audio Input - Becker AR6201 Installation And Operation Manual

The Last Channels Database of the transceiver updates automatically only
when operated in Standard Mode, Direct Tune Mode or Scan Function.
When a new Active Frequency stay selected for at least 10 seconds, the
VHF frequencies stored in LAST1, LAST2 ... LAST8 shift to LAST2, LAST3 ...
LAST9 and the current Active Frequency is stored as LAST1.
In Channel Mode the automatically stored frequencies "LAST" can be
recalled (see chapter 3.5.3).

3.10 Auxiliary Audio Input

The transceiver has an auxiliary audio input. In the Installation Setup,
enabling or disabling the auxiliary audio is provided (see chapter
2.8.5, page "CONFIGURATION").
Is the input enabled, the audio signal applied to this input is
transferred to the audio output(s) while the transceiver is in Receive
Mode.
Is the input disabled, the adjacent input signal will be ignored.
AUX AUTO MUTE function depends on the AUX INPUT is selected on
CONFIGURATION page in the Installation Setup (refer to chapter 2.8.5).
AUX AUTO MUTE function will mute the audio signal from the auxiliary
audio input automatically, as long as the AR6201-(X0X) detects (based on
squelch evaluation) a RX from the signal or user deactivates the squelch
manually.
If this function is disabled the signal from the auxiliary audio input
is permanently audible on the audio output, independently of the
received signal or the squelch status.
Automatic aux attenuation functionality is coupled with the auxiliary
audio input (Installation Setup, screen AUTO AUX ATT in chapter 2.8.5).
The level of the auxiliary input signal attenuates if intercom is
activated by VOX or by /IC discrete input. The auxiliary input signal
reverts to its previous value after intercom deactivation. The
attenuation value can be adjusted within the range from 0 to 40dB.
The auxiliary audio input signal is, if enabled and not muted, mixed
with the received signal from antenna and the intercom signal (if
squelch triggered and intercom activated).
3.11 Intercom Operation
The transceiver has an internal built in intercom. With activated
intercom the signals from the microphones are mixed and amplified to
become audible on headphone output. This enables internal communication
via headsets between both pilots.
Intercom operation in Receive Mode is also possible:
- Automatically via VOX (threshold adjustable in the Intercom Menu),
- Externally via intercom switch (pin P1-7).
