5. Operational safety precautions
Firstly make sure that the details for the supply voltage on the rear panel of the device correspond
to the available supply voltage at the operation location. If in doubt ask an electrician. Damages
sustained through operation of the device with incorrect supply voltage are not covered by our
warranty. Make sure that the power switch
o
is in the OFF position (O) before you carry out any
plug connections on the device.
It is also always worthwhile, when switching on, to return the input level controller
w
,
r
to the left
end stop so that the speakers will not be damaged by, for example, an unintentionally high signal
level at the input.
Always only use the best electrical outlets, which are also equal to the power requirements, for
power distribution to the devices. If the electrical outlets appear, for example, corroded or have
rusted contacts or they are equipped with cables that are too thin this will affect the performance
ability of the device.
Use only good speaker wires to minimize performance loss in the cables. If you want to connect
bare wires with the cable terminals it would be better if you first attached cable shoes to the cable
ends.
To supply the inputs of the device with a signal we recommend the use of quality high grade shielded
cables which are provided with a properly soldered, good XLR plugs.
6. Connecting the amplifier
Connecting the inputs
The balanced inputs have an impedance of 20 kΩ and are compatible with the Line-Level-Signals of
most devices. In the input you will find three pin XLR sockets as well as balanced jackplug sockets.
The built in 1/4“ jackplug inputs can be used with balanced or unbalanced signal sources.
This is the standard set-up with jackplugs:
Stereo (unbalanced):
Mono (unbalanced):
