A711
FEATURES
  • This unit is designed to provide high performance cockpit audio control in high noise installations
  • Compatible with the ACCESS/A family format, to allow fleet wide compatibility with all ACCESS/A installations
  • A711 has individual volume controls for the transceiver inputs
  • The high powered A711 audio controller delivers at least 332 mW of audio into 150 ohms at less than 2% total distortion to the pilot and co-pilot positions simultaneously
  • Delivers lower output powers into 300 and 600 ohm headsets
  • Pilot’s position may also be internally strapped to interface with 8-20 ohm headsets at the same power level
  • Push-button transmit selector switches allow immediate selection of any of the seven supported aircraft communications transceivers or PA amplifiers
  • The push-button audio input selector switches allows selection of any or all of the supported transceivers and Nav aids
  • ACCESS/A systems have auto-RX switching, when a transmitter is selected, to reduce pilot workload and avoid operational problems
  • Front panel selectable and adjustable VOX, LIVE, or KEYED intercom (ICS) functions
  • EMERGENCY mode push-button switch (switch and LED turn redorange when activated) provides "straight through" or “fail-passive” transmit and receive audio for the pilot on the selected communications channel
  • In the NORMAL position (switch turns black & LED 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
  • Provides ICS support and boom mic TX support for a complete aircraft crew, including the pilot, co-pilot, and up to 4-6 additional passengers
