Adjusting the AF level
Monitoring facility
Two infra-red transmission diodes are located behind the display window
on the modulator front panel. They transmit the complete infra-red signal for
monitoring purposes. Thus you can check the selected transmission channel
with a suitable receiver (e.g. an HDI 1029 PLL). The transmission distance
of the IR transmitter diodes is approx. 1.2 m.
By simultaneously pressing the buttons "
AF LEVEL
" and " + " or " - " you can
adjust the AF level for the transmission channel you have just selected.
With the " + " button you increase the AF level.
With the " - " button you decrease the AF level.
The level is adjusted correctly when the modulation indicator occasio-
nally reaches the red part of the display (full modulation).
When both buttons are released, the selected AF level is stored.
This completes all settings for the first audio input channel. For adjusting the
next input channel, start again with
CHOOSING THE AUDIO INPUT
.
Channel display All transmission channels used are displayed: When a given input delivers
its signal to an IR transmission channel, the corresponding LED
lights up.
