    AIRCOM Manual Basic Functions This chapter is dedicated to basic functions only. When you work with AIRCOM for the first time, we recommend to study this chapter step by step. Before you start, please set all volume controls to minimum (counter-clockwise position).

  • Page 10: Commentator Channels A And B

    AIRCOM Manual 5.2. Commentator Channels A and B 5.2.1. Inputs and Configuration Microphone inputs, XLR 3pole connectors labelled „MIC A“ and „MIC B“, are located on the rear panel. Prior to connecting a microphone use configuration bank 1 in order to perform an input configuration appropriate to your microphone.
  • Page 11 Note: Usually the limiter serves to suppress unattended high level peaks, which often occurs at on-site broadcast service. In case you use AIRCOM in a studio like environment, it might be more reasonable to switch off the limiter and leave the whole signal processing to a sound engineer on a mixing desk.

  • Page 12: Commentator/Interview Channel Guest

    AIRCOM Manual 5.3. Commentator/Interview Channel GUEST This channel is dedicated for a guest commentator or interview partner, as well as for feeding an auxiliary line signal into the unit. Hence it provides both, microphone and line input circuitry. There are no intercom facilities in the GUEST Channel.

  • Page 13: Channels A+Guest+B Sum Output

    AIRCOM Manual 5.4. Channels A+Guest+B Sum Output The audio sum of channels A, B and GUEST (-3dB summing) can be helpful in cases which do not require single commentator output lines. The output, 3pole XLR, is located on the rear panel labelled OUT A+GUEST+B.

    AIRCOM Manual 5.6. Monitoring Commentator A and B only, GUEST has no monitoring facilities. Each monitoring section provides 6 audio sources with individual level controls and a phones level control as a master. 4 sources are external: Program and Intercom inputs.

    Note 2: Unlike all other GPI Inputs GUEST LOCK is independent from REMOTE LINK mode, please also refer to Chapter 7.2 Compatibility note: Pin 7 may only be connected to 0V at AIRCOM units built from 2010. On units before this date, Pin 7 is connected to +5V internally! Rev.7a (for units from ser.no.

    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.

  • Page 21: Remote

    Since AIRCOM is in REMOTE LINK mode, the LEDs display the states of the control input with the same designation (refer to 7.3): OFF AIR LEDs light up red when the respective OFF AIR control inputs are activated, SC CUT light up green when the respective SC CUT control inputs are activated.

  • Page 22: Control I/O - Gpi I/O

    In order to prevent the operator error “commentator forgets to switch ON AIR” (e.g. after a show break) you can operate AIRCOM in ON AIR LOCK mode (refer to 6.1). Note concerning SC CUT: Practical examples for the use of SC CUT In some applications program monitor signal contains the commentator’s signal during parts of the...

  • Page 23: Examples Of Use

    Commentator A and B signals are fed into the intercom-system. Intercom return signals for the commentators are fed into the AIRCOM monitoring section. Main operation is performed at the AIRCOM unit. The main intercom contact can be addressed by TALK 1 button on the AIRCOM unit.
  • Page 24 OFF AIR control input at the AIRCOM (This implements the same behaviour, as if a TALK button on the AIRCOM front panel is depressed.). Intercom return signals are fed via AUX IN A and AUX IN B into the AIRCOM monitoring section (Refer to settings of 4-10 and 4-11.).

  • Page 25: Intercom And Commentator Audio Link Including Fail-Safe Operation

    Thus you use the infrastructure of the intercom-system and do not need to install separate audio lines. However, you may use the standard AIRCOM audio I/Os on a fail-safe system with redundant audio transmission. It takes over, if the intercom-system breaks down. E.g. connect sum output A+GUEST+B and PROGRAM input (maybe also COM3) to a failsafe-system.
