DESCRIPTION
The Technisonic Digital Audio Panel (TDAP) Audio Management System TDAP-611 is a panel
mounted Digital Audio System that provides centralized control and management for all audio
signals within the airframe for up to 7 distinct Users (Pilot, Co-pilot, and five passengers) with
varying degrees of connectivity depending on their station.
The TDAP-611 connects to all aircraft Transceivers (up to a maximum of 8 distinct Transceiver
Inputs), Navigational Receivers (up to a maximum of 8 distinct Receiver Inputs), Externally
Alerting Sirens, and User Headsets. The unit includes functionality allowing expansion to an
external PA or Paging system; it also supports full Simulcast transmitting as well as Monitor Only
functionality amongst all connected Transceivers.
To reduce pilot workload and avoid operational problems, ACCESS/D™ systems have auto-RX
switching when a transmitter is selected. The TDAP-611 has front panel selectable and
adjustable VOX, LIVE, or KEYED intercom (ICS) functions.
An EMERGENCY mode locking toggle provides "straight through" or “fail-passive” transmit and
receive audio for the pilot or other user on a pre-set radio.
In the NORMAL position (front panel LED is green), the pilot's audio is provided as selected by all
of the panel controls and is part of the ICS system. Separate RX and ICS volume controls are
provided on the panel along with an ICS VOX threshold control.
