Using the SV-INTERCOM-2S

This section provides guidance for using the SV-INTERCOM-2S.
4.1

Power

To manually power the SV-INTERCOM-2S on/off, press the volume knob.
The power switch remembers the on/off state. Once the SV-INTERCOM-2S is powered on,
aircraft power can be used to turn the Intercom on and off in normal use. Therefore, the power
switch need not be routinely used.
4.2

LED Power/Transmit Indicator

The LED indicator light in the center of the SV-INTERCOM-2S faceplate is green when the the
unit is powered on. When either the pilot or co-pilot PTT switch is depressed, the LED becomes
orange to indicate radio transmission.
The LED can be dimmed by a capable device such as a SkyView system. There is no manual
dimming control on the SV-INTERCOM-2S itself.
4.3

Volume

The volume knob adjusts the audio levels of the stereo music input and pilot-to-copilot intercom
communication only. It does not adjust the volume level of aircraft radios or other devices that
are connected. Adjust the volume levels on your radios and other audio devices to achieve the
desired volume balance between all audio devices in the aircraft.
4.4

Squelch Adjustment

The SV-INTERCOM-2S has voice-activated (VOX) microphone channels to reduce background
noise from the aircraft when no one is speaking. When either the pilot or co-pilot speaks into
their headset, their microphone channel is activated, allowing them to be heard by the other
person. The microphone audio level that is required to activate a microphone channel is adjusted
with the squelch knob.
To adjust squelch with the engine running:
1. While no one is talking, turn the squelch knob until you hear background noise in your
headset.
2. Adjust the squelch until you no longer hear background noise.
3. With the microphone close to your mouth, talk to confirm that normal speech levels
activate the microphone. The VOX feature will automatically close the microphone after
you finish speaking.
To reduce background noise, the pilot and co-pilot microphones are activated individually.
