3.4.10. MIC – Setup
Each of the two microphone inputs channels can be configured
individually, which enables different microphone types to be used.
A maximum of two microphones of same type may be connected to each
microphone input channel (see Microphone Connection 5.6.1).
The MIC – Setup is the last item of the Audio menu and can be accessed
by pressing the AUD button nine times.
By pressing the DUAL button repeatedly L, R and AUTO can be selected.
L (R) means left (right) microphone input channel. The AUTO function is
explained later.
By means of the turning knob the displayed microphone input channel
amplifier gain (MIC-level-01-=-low-gain,-09-=high-gain) can be selected
individually. The microphone signal level is dynamically displayed as bar
and as numeric value (from-0.00-to-1.00) in the line below.
The initial MIC-level should be 05, the engine should be running, use a
headset or earphone and speak at a normal voice level to fine-tune the
MIC-level. Whenever a new MIC-level was selected, the dynamic bar
indicator should then be at about 50%.
When the microphone setup menu is left, the new value is stored.
The range of the MIC-level for standard microphones is 01 to 09.
