Dynon Avionics SV-INTERCOM-2S - Manual (Page 20)

Using the SV-INTERCOM-2S
3-2 SV-INTERCOM-2S Installation and User Guide - Revision A
LED Power/Transmit Indicator
The LED indicator light in the center of the Intercom is green when the Intercom 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 Dynon SkyView system. There is no
manual dimming control on the SV-INTERCOM-2S itself.
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.
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.
Adjust squelch with the engine running:
First, while no one is talking, turn the squelch knob until you hear background noise in your
headset.
Next, adjust the squelch until you no longer hear background noise.
Finally, with the microphone very near your lips, 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.
Front Music In Jack
The SV-INTERCOM-2S has wiring provisions for a permanent stereo music source via its rear-
mounted wiring connector.
A music device can also be plugged in to the standard 3.5mm Music In jack on the front of the
intercom. When a device is plugged in to the Music In jack, it over-rides the permanent music
input.
