SR20

• Right Outer Knob – Copilot and passenger mic VOX level. CW

rotation increases the amount of mic audio (VOX level) required

to break squelch. Full CCW is the 'hot mic' position.

Each microphone input has a dedicated VOX circuit to assure that only

the active microphone(s) is/are heard when squelch is broken. After

the operator has stopped talking, the intercom channel remains

momentarily open to avoid closure between words or normal pauses.

Control

The Audio Control Panel provides an adjustable Voice Operated Relay

(VOX) Squelch Control for the pilot, copilot, and passengers. Since the

VOX circuits reduce the number of microphones active at any one

time, the amount of unwanted background noise in the headphones is

diminished. This also allows the use of dissimilar headsets with the

same intercom. Because the user can adjust the trip level of the VOX

squelch to fit the individual voice and microphone, this helps eliminate

the frustration of clipping the first syllables. There is a slight delay after

a person stops talking before the channel closes. This prevents

closure between words and eliminates choppy communications.

To adjust squelch:

1. With the engine running, set the VOX trip level by slowly rotating

the SQL control knob clockwise until you no longer hear the

engine noise in the headphones.

2. Position microphone near your lips and speak into microphone.

Verify that normal speech levels open the channel.

Intercom Modes

The GMA 340 provides three intercom (ICS) modes to further simplify

workload and minimize distractions during all phases of flight: PILOT,

CREW, and ALL. The mode selection is accomplished using the

PILOT and CREW push-buttons. Pressing a button activates the

corresponding ICS mode and pressing the button a second time

deactivates the mode. The operator can switch modes (PILOT to

CREW or CREW to PILOT) by pressing the desired modes push-
