In order to connect MLM A to C (microphone/loudspeaker modules = user units comprising loudspeaker, microphone
and button), you should use original Behnke patch cables
.
The integr
ated add-on amplifier (1 W) can only be activated for MLM A. The corresponding configuration steps can be
found in our comprehensive technical manual (available as PDF on the Internet – see also note on page 2).
Connection of multiple MLMs reduces the maximum distance between MLM and basic electronics package:
1 MLM = 25 m / 2 MLMs = 12.5 m each / 3 MLMs = 10 m each
