Section 3.0 Operation
3.1 Introduction
Information in this section consists of the functional and operational procedures for the
AMS43 Single Channel Audio Controller.
3.2 General
The AMS43 provides control for all aircraft audio, allowing selection of transmit (TX) and
receive (RX) audio, LIVE, KEYED, or voice activated (VOX) intercom, interface for an
additional hand held transmit microphone (hand mic), and pilot isolation/emergency
(PILOT ISO/EMR) operation.
Sidetone (S/T) level is adjustable internally, and RX and intercom (ICS) levels are
adjustable on the front panel. All audio, except the S/T of the radio in use and the directly
connected DIRECT AUDIO 2 input signal (see Section 3.5.1), is muted during TX for clarity.
ICS operation allows TX during any ICS mode by using the push-to-talk (PTT) switch.
3.3 Controls and Indicators
All TX and public address (PA) functions are controlled with a single rotary selector
switch. RX audio, ICS operations and tape audio are controlled with colour-coded
toggle switches. RX volume, ICS volume and ICS VOX squelch are individually
adjusted with rotary controls.
