Intercom/4 Place/Vox/Ptt AA80-020

The AA80 (AA80-020) InterVOX is an advanced cockpit intercom system designed for general aviation pilots. The InterVOX provides full boom-mic transmit and ICS operation for the pilot, co-pilot, and two or four additional passengers. Also, the AA80 intercom offers a stereo tape input (AA80-001 only) mute during transmit and ICS operations and a pilot privacy function. Transmit ICS allows immediate transmission from the ICS mode without any additional switching. The InterVox system uses unique audio processing for dynamic noise reduction and selective bandwidth for producing clean intercom audio under noisy conditions — resulting in better onboard communications and reduced noise fatigue. The AA80's high output power and low distortion ensures adequate volume for all types of headset and flying conditions.

• Full boom mic transmit and ICS for pilot, copilot, and up to four passengers
• Split bus operations and automatic emergency switching during power failure are standard features
• Internal over-voltage and reverse voltage protection
• Built with high quality components such as sealed gold plated contacted switches, dry nitrogen filled/high vibration rated sealed relays, gold contact connector and a fully masked, post coated, flame retardant circuit board
