AIRCOM-IR Interpreter Remote unit required
In an interpreter application AIRCOM is used with only one microphone. The microphone signal has to
be switched alternately between output A and B.
When IR MODE is configured, connect the interpreter microphone and headphones to AIRCOM
Commentator A. Microphone input B is disabled. Microphone A signal is fed pre-Limiter to both channels.
Concerning microphone configuration for B channel, you can ignore the settings for phantom power,
20dB Pad and LoCut, but Limiter has to be set for both channels, A and B, if required.
AIRCOM in IR MODE is operated by our Interpreter Remote unit AIRCOM-IR.
Lever left position: A
active
Lever right position:
B active
Lever centre position: A and B off
Two LED displays left and right of the lever switch, designated A and B, are controlled by the AIRCOM
logic parallel to the ON AIR button displays: red=active, yellow=off.
Connect AIRCOM-IR to the 37pole Sub-D REMOTE GPI/AUDIO connector on the AIRCOM rear panel. Set
AIRCOM configuration to REMOTE ENABLE (ref. to chapter 7.2) and ON AIR LOCK (ref. to chapter 6.1).
AIRCOM-IR is pre-wired to activate IR MODE. It takes advantage of AIRCOM REMOTE LINK Mode in
combination with the OFF AIR GPI Control Inputs.
Note 1:
As a standard, AIRCOM-IR is pre-wired to permanently switch GUEST channel OFF AIR. If you
need this channel when in interpreter mode, you can easily remove a jumper cable from AIRCOM-IR
Sub-D connector (refer to chapter 7, Remote, and to AIRCOM-IR documentation).
Due to integrated weights and skip-proof
rubber feet the remote unit is perfectly
suited to desktop operation.
Its small size make it a perfect hand-held
device as well. As the lever gives a clear
tactile feedback of the switch position it
can be operated without being in the
visual field of the operator.
The switch is equipped with a special low
noise mechanism.
Note 2:
Do not forget to set Sidechain
and
Co-Comm monitor level controls on the AIRCOM, so the
operator can hear his microphone signal when A
or
B is active. In case the operator prefers to listen to
his microphone signal independent of ON AIR or TALK status, select CONFERENCE (ref. to chapter 5.6.5)
to provide “pre-“ monitoring for A and B channel.
ComLink:
When using IR MODE, another control option concerning TALK buttons 1-3 should be used.
Pushing a TALK button on the AIRCOM deactivates ON AIR of the
respective
commentator channel. As
there is only one operator in IR MODE, it is mandatory that pushing any TALK button (1-3) should
deactivate both channels, A and B.
As a standard, AIRCOM-IR is pre-wired to performed this action by using AIRCOM GPI Control logic in
combination with REMOTE LINK mode.
AIRCOM-IR units, pre-wired with this option, are labelled “ComLink” on the bottom plate.
