Garmin GMA-35C remote mount Audio Processor

This is a digital audio system featuring integrated Bluetooth connectivity, designed specifically to be remotely mounted and controlled directly through the touchscreen interface of a Garmin GTN 725, GTN 750, or GTN 750Xi navigator. Because it is a completely remote-mounted box with no physical buttons or faceplate controls of its own, it cannot function as a standalone unit.

Description

This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 9/23/2026.

Key Technical Capabilities:

  • Integrated GTN Control: Eliminates physical buttons and saves cockpit panel space by moving all audio panel selections, volume sliders, and intercom controls directly onto a paired GTN 725, GTN 750, or GTN 750Xi touchscreen interface.
  • Wireless Bluetooth Connectivity: Enables pilot, copilot, and passengers to pair smartphones or tablets to wirelessly stream telephone calls, listen to entertainment audio, and receive cockpit alerts.
  • 6-to-7 Position Voice-Activated (VOX) Intercom: Uses independent, dedicated auto-squelch processing for every headset microphone to automatically adapt to ambient cockpit noise levels without cutting off words.
  • Digital Clearance Recorder: Continuously captures and stores up to 2.5 minutes of incoming radio transmissions, allowing pilots to instantly replay complex air traffic control instructions.
  • Split-COMM Capability: Allows the pilot to transmit and receive on COMM 1 while the co-pilot simultaneously and independently communicates on COMM 2.
  • 3D Audio Processing: Simulates spatial sound separation within stereo headsets, making it easier for the pilot to differentiate between multiple audio sources (like listening to ATIS and ATC at the same time).
  • Advanced Target Squelch: Automatically suppresses background engine noise and adjusts microphone thresholds dynamically, ensuring crystal-clear intercom communications even in high-noise aircraft environments.
