WARNING The AC /AC adaptor uses danger-
ous mains voltage (230 V~). To
prevent a shock hazard do not
open the cabinet. Leave servicing
to authorized skilled personnel
only.
It is necessary to observe in any case the fol-

4 Connecting the Unit
The microphone
switched off if connections to other units are
going to be made resp. changed.
1) The power supply of the microphone pre-
amplifier is either via the provided AC/AC
adaptor (15 V~) or – for the mobile use
of the unit – via four 9 V transistor batteries.
The inserted batteries are disconnected
during power supply via the AC/AC adaptor.
- For supplying the unit via the AC/AC a-
