Transducer
Rear Panel
Power Connection
Before you connect the Transducer to any local power source, be SURE to check that the rear
panel voltage switch is correctly set for your local area (115V position: 110-120V, 230 V posi-
tion: 220-240V).
Connect the included power chord to the rear Mains Input. Transformer, power chord and
case connection conform to VDE, UL and CSA requirements. Power fuse ratings are 200 mA
slow blow (230 volts) or 400 mA slow blow (115 volts).
On and Off
In switching on and off, you need not follow any particular sequence. Even when the amp
is running and the Transducer is shut off, the latter works as a passive resistance circuit.
Therefore the amp is not loaded more heavily by a switched off Transducer as it is in the case
of a connected cabinet.
Signal Connections
Before fi rst connecting any other equipment – and in all other cases where you are connec-
ting cables with or from other sources – you should be sure to shut the Transducer and all
machines to be connected off (rear panel power switch). Otherwise you risk to damage the
unit, connected gear or your ears.
XLR Connections
The diagram shows how to wire the balanced XLR output connections if unbalanced connec-
tions are required.
For further information on the XLR connections (pin wiring) please refer to the descriptions of
the respective outputs on the following pages.
1/4" Jack Connections
The 1/4" Jack connections of Pre Simulator and Speaker Thru output as well as Power Input
are unbalanced.
The balanced TRS connector of Line Output 2 can be used both with balanced and unbalanced
(=mono Jack connection) wiring.
For further information on the Jack connections (pin wiring) please refer to the descriptions of
the respective inputs and outputs on the following pages.
