Product Description

The Digital Audio Control System (DACS) is a communications management system with the ability to distribute and control all audio in an aircraft, to/from all transceivers, receivers and audio warning sources. The integrated, multi-channel intercom system and programmable user definition allow the audio system to be configured to suit customer specific communication schemes.

The major components in the system are Audio Control Panels (ACP51 and/or ACP53), Audio Management Unit (AMU50), Remote Memory (RM01), and optional Passenger Intercom Amplifier (PIA01). The primary component in the system is the Audio Management Unit. Connected to it are transceivers (up to 8), receivers (up to 8), Direct Audio inputs (up to 6), Audio Control Panels (up to 6) and one Passenger Intercom Amplifier (PIA). The Audio Management Unit distributes all radio audio to each user and to the Passenger Intercom Amplifier. Seven headsets can be connected to the Audio Management Unit (basic configuration is two crew and five passengers). Each passenger headset can also be assigned to a specific ACP, upgrading the passenger to a fully capable crewmember. More than one headset can be assigned to an ACP. The system architecture is a star configuration (separate serial connections to each Audio Control Panel and Passenger Intercom Amplifier) to prevent loss of the entire system because of a failure of one connection.
