Using the SV-INTERCOM-2S
The SV-INTERCOM-2S is a 2-Place Stereo Intercom for Sport Aircraft. It includes features:
Ample inputs for EFIS systems, stereo music, and all the other technology in your panel.
High-Fidelity Audio Circuitry: No more scratchy, garbled voices. Stereo music that sounds
fantastic!
Dual Radio Support: The SV-INTERCOM-2S has dual radio outputs for the well-equipped panel.
Fail-safe between the pilot headset and primary radio that allows communication without
intercom power.
Horizontal and Vertical faceplates are both included; headset jack kits also included.
Selectable Auto Mute turns down the music when a radio or other non-muting input (like an
EFIS alert) receives audio. A single knob press toggles whether or not intercom speech also
mutes music.
Independent intercom Voice Activation reduces background noise; talking on one headset
won’t open up squelch on the other. Radio broadcasts are also isolated so that only the person
pressing the PTT is heard over the air.

Power
To power the SV-INTERCOM-2S on and off manually, press the volume knob.
The power switch remembers its 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 used in routine operation.
