SM50 Rev. 4.00 AMS50-000 Stereo Audio Panel Manual
Section 1.0 Description
1.1 Introduction
This manual contains information on the AMS50-000 Stereo Audio Panel.
Information in this section consists of purpose of equipment, features and specifications.
1.2 Purpose of Equipment
The AMS50-000 is a full-function stereo audio panel with a six-place, voice-activated
(VOX) intercom and an optional built-in Marker Beacon receiver. The front panel
controls feature clean responsive switching for crucial audio management. Transmitter
and receiver selections are quick and precise using soft touch push-buttons. Positive
feedback is provided in two formats: tactile and visual (colored LED's).
1.3 Features
Radio functions include independently selectable transmit capability for Pilot and Co-pilot
on 3 COM radios. Pilot’s transmit selection also has remote capability (yoke or cyclic).
Receive audio selections include: COM1, COM2, COM3, MKR, NAV1, NAV2, DME and
AUX. COM3 is configurable at time of installation for use with an aviation phone.
The built-in six-place VOX intercom system with ALL, CREW, and PLT ISO modes,
features NAT’s Active Noise Filtering (ANF
) system. This advanced technology filters
out unwanted ambient noise entering the intercom channel, thus better isolating the
human voice. Clear, clean intercom communications result in a safer and more
comfortable flight.
Wind, engine and other fatigue noises are significantly reduced within the intercom
system by utilizing independent microphone circuits. By ‘turning on’ only the active
microphone, internal communications are quieter and less stressful.
Protection circuits help to prevent accidental damage from overvoltage and reverse
voltage conditions.
Accommodation is provided for two (2) direct unswitched inputs for functions such as
telephone ringer, Rad Alt, GPS alerts, and an Option Select input controls firmware
related functions (i.e. Karaoke).
Automatic fail-safe operation is provided in the event of a power failure. The Pilot is
routed directly to COM1 and the unswitched direct audio inputs. This mode can also be
manually selected using the OFF (EMG) switch (see section 3.2.5.3 of this manual.)
