Specifications

NOTE: Headsets are of the double or single muff type. In case of using a double muff

headset, the two speakers should be wired in parallel.

HEADSET SIDETONE CONTROL

The headset sidetone control adjusts the level of your own voice as you hear it in

your headphones. Prior to use the Sidetone control, a good null of the four lines must be

done. See next paragraph NULL CONTROL description. When the null has been done in all

the used channels, your own voice is almost inaudible on the headset at minimum sidetone

setting.

Side tone is mainly used when you wear double muff headsets models so being very

isolated from the outside ambient and also from your own voice. This causes an

undesirable overmodulation of your voice to the others party. An adequate sidetone

regulation allows a comfortable voice modulation and talk level to the intercom system.

When using single muff headsets, the settings of the sidetone control are normally lower

than using double muff.

HEADSET VOLUME CONTROL

The volume control allows attenuating or amplifying the signal sent to the

headphones. This control adjusts the listen level to the headphones.

PANEL MIC GAIN CONTROL

The panel microphone gain is adjustable by a potentiometer between +20 and +50

dB.

configured to allow this key to toggle between panel mic and headset mic or headset

mic always on (factory default). You can also configure the operating mode of the switch:

Push to talk only, disabling latch operation or push to talk + latch mode. On this mode, push

to talk or latch is recognized by the time the key is depressed. Short keystroke produces

latch action and long time, momentary action. (factory default).

channels around the intercom system (including all the wired and wireless beltpacks, desk

station units and master station slave units) except the base station microphone..
