6 Place Stereo Expansion Unit AA82-060

The AA82 (AA82-060) InterMusicâ„¢ intercom system is designed to meet the needs of pilots and crew in demanding environments. This InterMusicâ„¢ unit supports up to six positions and can be linked via a tie line to the forward flight crew  when using an AA83 intercom system. The AA82 offers passengers full control of their intercom and entertainment functions. The front panel controls allow users to adjust their intercom level, VOX threshold, and music level. Receive level, receive balance, ICS balance, ICS bass, music muting and balance can  be set using internal controls. With these controls, users can make intercom audio appear to be coming from the left and receive audio from the right, this is useful to assist users in identifying the source of incoming audio. Stereo audio is muted during incoming transmissions to increase intelligibility. A front panel indicated allows easy visual setting of VOX threshold and indicates RX signals.

• ANFâ„¢ (Active Noise Filtering) provides clean and clear intercom communications by filtering out unwanted ambient noise
• Built with high quality components such as sealed gold plated contacted switches, dry nitrogen filled/high vibration rated sealed relays, gold contact connector and a fully masked, post coated, flame retardant circuit board
• Pilot Isolated Mode provides pilots with a separate communications channel that is separate from passenger intercom or music
• Music is muted during all radio and ICS activity and slowly returns to normal volume when ICS operation is finished
• 11 to 32 VDC power input
• Headset output power rating: 100mw into 600Ω per channel
• Bicolor LED-ICS/Tx activity indicator lights up amber for ICS activity and green for transmit 
• Pilots can override the co-pilot during radio operations
• Individual microphone gating reduces aircraft noise within the intercom through independent microphone circuits
• Horizontal or vertical mount options available
• Emergency Fail-Safe automatically bypasses the ICS feature and is routed back to the radio audio system in the event of power loss
• Short circuit protection ensures continued operation in the event of headset failure
