Section 1.0 Description
1.1 Introduction
The AA80 InterVOX is an advanced cockpit intercom system for general aviation flying. Built to the same
exacting standards as AEM’s widely accepted AA9x/AMS series of audio controllers, the AA80 offers
exceptional quality and performance at an attractive price. Since the InterVOX has more than three times
the output power of current Sigtronics SPA400 or David Clark Isocom systems, as well as many more
pilot convenience features, substantial operational improvements can be made using the AA80 over other
systems.
1.2 Purpose of Equipment
The InterVOX provides full boom-mic transmit and ICS operation for the pilot, co-copilot, and 2 or 4 additional
passengers, as well as offering a stereo tape input (AA80-001 only) muted during transmit and ICS operations,
and pilot privacy function. Transparent ICS (a standard feature on all AEM systems) allows immediate
transmission from the ICS mode without any additional switching. All the features of the AA80 have been
geared to reduce the pilot’s workload while providing the best possible operating features in flight.
1.3 Design Features
The InterVOX system employs AEM’s unique audio processing system of dynamic noise reduction, and
selective bandwidth to produce clean, crisp intercom audio under difficult and noisy conditions. This
results in better on-board communication and greatly reduced pilot noise fatigue. The high output power
and low distortion of the AA80 ensure adequate level for all types of headsets and flying conditions. Split
bus operation AND AUTOMATIC EMERGENCY SWITCHING (back to the regular aircraft system) during
power failure are standard features. The AA80 has internal overvoltage (>33V) and reverse voltage
protection.
Unlike many systems targeted at light aircraft, the InterVOX uses extremely high quality components,
including sealed gold contact switches; dry nitrogen filled, high vibration rated sealed relays; gold contact
connectors; and a fully masked, post coated G10 flame retardant circuit board. Each unit is fully
temperature cycled and life-tested.
