Changing the transmission channel
To avoid interference caused by the
simultaneous operation of several
1/3
transmitters, select a different channel
on each transmitter. Several
switchable transmission channels are
available (C ).
HANNEL 2
Due to the required approval two
channels are selectable:
Positions 1 or 3 = channel 1 Position 2 = channel 2
Turning the automatic compression system on
Use the COMP switch (compression) at the rear of the transmitter to turn the
automatic compression system on. This system reproduces soft passages
louder and decreases loud sounds.
Use the MO/ST switch to choose between mono and stereo transmission.
For mono TVs and when using the MKE 800 TV microphone, the switch must
be set to mono (MO).
