2, 4 or 6 place Intercom System
ICS Tie Line NAT’s exclusive feature allows the panel to be part of a complex multi-unit system as either a primary or secondary component.
Pilot / Crew / All Modes Three position toggle switch allows pilot and crew isolation from passengers. Both the crew and passengers retain full intercom and music capabilities within their group while passengers are prevented from hearing any radio communications during ‘isolated’ operation.
VOX / LIVE / PTT Modes The intercom mode is set by the position of respective VOX controls. Separate VOX controls for the pilot and crew/passengers compensate for the differences in noise levels and headset types between the front and rear of the aircraft.
Stereo Music Input Accepted from either portable entertainment units, CD changers, or other integrated onboard systems. Sophisticated channel mixing delivers high quality monaural music to standard aviation headsets.
Adjustable Music Mute / Radio Input Levels (Internal) eg. Music mute level can be adjusted to mute 50% for passengers and 100% for the crew. Radio volume levels can also be set at a lower level for passengers while maintaining optimum volume for the crew.
AA80 Compatible and AA82 Expandable
NAT Intercoms General Information
NAT Intercoms (General): Designed to satisfy demanding environments, Northern Airborne’s general aviation intercoms are high quality, rugged, compact, voice activated systems with many of the features found in larger commercial aircraft. NAT’s exclusive state of the art technology ensures clear, crisp communications throughout the aircraft without annoying clipping, which often occurs with relay-activated systems. All NAT panels are loaded with features that will satisfy most aircraft audio system requirements.
ANF™ (Active Noise Filtering): This advanced technology helps to isolate the human voice while filtering out unwanted ambient noise entering the intercom channel. Clear, clean intercom communications result in a more comfortable and safe flight.
Quality Enhanced by SMT: Our products use 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, flame retardant circuit board. Each unit is temperature cycled and life tested.
Pilot Isolate Mode: Separates the pilot from the system, allowing confidential radio communications without interference from passenger intercom or music.
Gradual Return of Music Mute: Music muting is automatic during all radio and ICS activity. Upon conclusion of radio or ICS operation, the music gradually returns to its previous level.
Power Input: 11 - 32 VDC
Headset Output Power: 100mW into 600 ohms per channel, typical
Bicolor LED-ICS/TX Activity: Indicates amber during ICS activity and green during transmit.
Pilot Priority Transmit Override: Allows the pilot to override the co-pilot (or instructor to override the student) during radio transmissions.
Patented Individual Microphone Gating: Aircraft noise is significantly reduced within the intercom through independent microphone circuits. By "turning on" only the active microphone, internal communications are quieter and less stressful.
Mounting Options: Vertical or horizontal. See outline drawing 5-1 for dimensions.
Emergency Fail-Safe: In the event of a power failure, the ICS is automatically by-passed and the pilot is routed directly to the radio audio system.
Short Circuit Protection: Provided to ensure continued operation in the event of a headset failure.
