Audio Management Unit (AMU)
• Ensures interface between jack and ACP and various radio communication and navigation systems
• Serves to records communication (CAA recording)
• Equipped with test circuit which connects to CFDS and ensure following functions
• Transmission – Collects microphone inputs of the various crew stations and directs them to communication transceivers
• Reception – Collects them from various outputs from communication and navigation transceivers and directs them to crew stations
• SELCAL
• Enables reception with aural and visual indications of calls from Gnd. stations equipped with coding device
• SELCAL decoding unit located in the AMU
• Display of Gnd. crew and cabin attendant calls
• Ground call
• When call P/B pressed on the External power control panel (108 vu), Gnd. signal send to the selcal/call card and FWC. FWC activates the buzzer and sends to the F/D amplifiers in the AMU to broadcast through loudspeakers. SELCAL/CALL card sends signal to ACPs via audio cards to illuminate CALL Lts.on the ACPs for 60 secs.
• Call automatically resets after 60 secs or manually reset by pressing reset P/B
• Attendant call
• When call initiated from the cabin attendant station CIDS directors send Gnd. signal to selcal/call card sends signal to ACPs via audio cards to illuminate CALL Lts. on the ACPs for 60 secs. CIDS directors also sends a signal to FWC to activate the buzzer for 1 sec. and sends to the F/D amplifiers in the AMU to broadcast through loudspeakers.
• Call automatically resets after 60 secs or manually reset by pressing reset P/B
• Flight Interphones
• Allows intercommunication function in the flight deck various crew stations, with ground interphone jack and avionics compartment
• Emergency function of capt’s and FO’s stations
• Only digital data are exchanged between AMU and ACPs, NO audio signal in the ACPs
• In side the AMU switching, filtering and amplifications will be done, one audio processing card for each ACP
• Volume control function will be done by digitally in the AMU
• Muting for the captain’s and FO’s loud speakers during transmission will be done by AMU
• Attenuating function will not be operative with the FWC audio outputs Audio switching selector
