The following microphone inputs are available:

Microphone Input Left

Right

standard

MLS

MRS

dynamic

MLD

MRD

With VOX set to 5 previously, select the microphone to adjust with

For each microphone input, with running engine speak with normal
volume into the selected microphone, and use the

rotary knob

to adjust the sensitivity, so that the bar reaches the middle of the
scale, as depictured above.

Per microphone input a maximum of two parallel installed microphones
may be connected. (see 4.6.1)

Every microphone input’s sensitivity can be individually
configured, in order to achieve equal volume with all
microphones.
