AMS 42/44 Dual Channel Audio Panel / ICS

Dual Channel: Specifically designed for special mission applications, the AMS42 and AMS44 have dual radio controls to independently select radio transmit and receiver audio. The dual channel configuration provides independent radio control for pilot and co-pilot within the space of a single controller plus intercom support for the crew and five passengers. Each pilot can choose the communications set-up specific to their role in the mission. The pilot can be selected on COM 1 while the co-pilot transmits and receives on FM 2 for true split transmit capabilities.

A full selection of receiver select switches are provided for each channel to further enable the pilots to remain independent from each other. The AMS42 and AMS44 have transmit capability for 5 COMs with “Auto-receive” function. The AMS44 has select monitoring switching for each COM plus 5 NAVs. The AMS42 has receiver select switches for the first 4 COMs. COM 5 is set up for auto-receive only. NAV inputs are selectable by internal dip switches. The AA92H and AA94 series provide the ability to customize controllers to meet specific needs and missions.

Intercom: An integral intercom features one of the highest headphone outputs in the industry with up to 500 mW per channel. Single channel controllers support 2 crew plus 4 passengers, dual channel controllers support 2 crew plus 5 passengers. The intercom system features NAT’s unique high performance Active Noise Filtering (ANF™) system to achieve the best possible intercommunications in noisy aircraft environments. Voice activated squelch (VOX) uses NAT’s voice-tracking circuit that combines low noise audio processing with selective voice-band squelch triggering for effective hands-free ICS operation. Dual channel controllers provide a Pilot Isolate mode to allow the pilot to separate from the intercom system for complete isolation.

Direct Inputs: Two direct inputs accommodate functions such as Rad Alt, GPS Alerts, Low Rotor, or Telephone ringer.

AMS43 Single Channel Audio Panel /ICS

Single Channel: The AMS43 series is a standard controller providing transmit and intercom (ICS) capabilities for pilot and co-pilot plus intercom for 4 passengers. Panel controls include a master RX volume, ICS volume and ICS squelch (VOX) adjust. “Auto-receive” function is standard along with selectable receive switches for coms and nav sources. An ICS Tie line is provided to allow multiple controllers to be networked. The AA95, 96 and 97 controllers can be custom configured to support up to 6 transceivers or 5 transceivers plus PA.

Intercom: An integral intercom features one of the highest headphone outputs in the industry with up to 500 mW per channel. Single channel controllers support 2 crew plus 4 passengers, dual channel controllers support 2 crew plus 5 passengers. The intercom system features NAT’s unique high performance Active Noise Filtering (ANF™) system to achieve the best possible intercommunications in noisy aircraft environments. Voice activated squelch (VOX) uses NAT’s voice-tracking circuit that combines low noise audio processing with selective voice-band squelch triggering for effective hands-free ICS operation. Dual channel controllers provide a Pilot Isolate mode to allow the pilot to separate from the intercom system for complete isolation.

AA12S Stereo Audio Panel / ICS

The small size and extensive radio and intercom functions of the AA12 Series make this an excellent choice for many installations. The new AA12S compact stereo audio controller provides high performance audio to four positions with LIVE/KEYED/VOX ICS modes. The AA12 mono-aural units provide support for six positions. Two positions have full RX/TX/ICS capability, with the balance of the positions having RX/ICS only. Pilot ISO operation, automatic fail passive switching for the pilot, and TX annunciation are standard features on the AA12 and AA12S. Music input is available and is muted during ICS, RX and TX operation. Operational for either 14 VDC or 28 VDC aircraft (specify voltage for panel lights). The AA12 is also available in a 6.25" tray mount version.

NPX138N

NPX Series General Description:
NAT’s family of self contained panel mount FM transceivers are designed as stand-alone, mission specific radios. Their lightweight compact design is perfect for the space and weight restriction of helicopters and light fixed wing aircraft. Incorporating NAT’s proven, user friendly Tac/Com II™operating system, the NPX series is simple to program and easy to use. Main volume control and a scan select switch are conveniently located beside the display. The squelch test, channel up/down, and display brightness controls are easily identified along the bottom of the panel. A separate guard volume and guard transmit select switch is provided. With no complex patterns or codes to memorize, the NPX’s straight forward controls and online "Help" screens insure intuitive operation. PC software is available for fast, convenient programming of complete channel information. The capability to upload and download NPX channels allows users to store multiple sets of operating frequencies for quick transitions between contract assignments. These compact radios incorporate solid chassis construction, user friendly controls and are tested to stringent aircraft environmental standards. Whether the mission is forestry, law enforcement, business communications or other applications, the NPX family of radios will satisfy the most demanding operational needs.

NPX138N:
This USFS compliant radio was specifically designed to fulfill contract required functionality. The synthesized frequency-agile transceiver allows easy access to all pre-programmed channels and the ability to modify or add channels on the fly.

At less than 2" high and 3 lb., NAT’s self-contained panel mount NPX138 radios are designed as stand-alone units for the single mission user. The lightweight state-of-the-art compact design is perfect for the space and weight restricted environment of a helicopter or light fixed-wing aircraft.

Each of the 100 memory channels available can store a receive frequency with CTCSS tone, a transmit frequency with CTCSS tone, scan function and an alpha-numeric identifier on a 32 character LED display. Transmit power of 1 or 10 watts is easily selectable from the front of the NPX.

The optional synthesized two channel guard receiver allows front panel tuning of user frequencies, ensuring communication integrity during complex flight operations. Each individual channel is operator selectable for wide (5 kHz deviation) and narrow band (2.5 kHz deviation) operation. DTMF encoding and direct keyboard programming can be added using NAT’s DTE12.

Panel lighting is available in either 28, 14 or 5 VDC controlled through the aircraft dimmer bus. NVG compatible lighting is optional.
