1.3 EQUIPMENT DESCRIPTION
The SL10-series is a state of the art audio isolation amplifier and audio selector that contains a voice
activated (VOX) intercom system. It can switch up to three transceivers (Com 1, Com 2 and TEL) and six
receivers (Nav 1, Nav 2, ADF, DME, MKR and AUX). In addition, there are two unswitched inputs, for
telephone ringer and altimeter warning. Push buttons select the receiver audio source provided to the
headphones. A SPR button allows the user to listen to the receiver(s) selected on the cabin speaker. Except
for the unswitched inputs, all speaker audio is muted during transmit. A rotary switch selects one of the
three transceivers for the pilot and copilot position in transmit. In "Split Mode" the SL10 has the ability to
allow the pilot and copilot to operate different transmitters independently and simultaneously.
A fail-safe mode connects the pilot headphone and microphone to COM 1 if power is removed for any
reason, or if the Mic Selector switch is turned to the Off position.
A six-station voice activated (VOX) intercom is included in the SL10. pilot isolate and crew modes, two
mono (or stereo depending on unit) music inputs with "Soft Mute," and a 2-color Light Emitting Diode for
power and transmit indications. Intercom control is through front panel mounted knobs. Monaural units
have a dual concentric knobs that control pilot volume and intercom squelch, and copilot/passenger volume
and squelch. In the stereo versions, there is a single volume and squelch control for all on board.
An optional 3-light Marker Beacon receiver is integral to the SL10M and SL10MS. This provides the
necessary Marker Beacon light and audio indications necessary for an Instrument Landing System (ILS)
approach.
