The wiring of the connection cables is as follows:
The device must be earthed!

Speaker Impedance
Following table shows the impedance for different speaker combinations – each speaker has an individual
impedance of 8 ohms:

Stereo Operation
This is the normal operation mode of an amplifier, in which every channel gets its own signal. The most commonly
used mode of amplifiers is stereo operation at 4 ohms. Make sure that the mode selector is correctly set (see
"7.b.7").
Remark: The input impedance of the speaker system should at least be the same or even higher than the output
impedance of the amplifier.
Parallel operation
In parallel operation mode the voltage remains the same but the current is doubled. Consequently, the output
impedance is limited to the minimum value of one individual channel. Connect the input signal with the input of
channel 1 (make sure that the amplifier is disconnected from the mains before you set the mode selector to
parallel). Bridge the red pole socket of output channel 1 and output channel 2.
CAUTION! Before switching on your amplifier, please refer to the explanations under "10. Operation". Adjust the
level with the gain control CH-1 on the front panel.
Bridged Operation
Possibility to run the amplifier in mono via one input channel. In bridged operation mode, the voltage is doubled.
Consequently, the output impedance is doubled.
For stereo operation, 2 amplifiers are needed. Connect the input signal to the input CH-1 on the rear panel. Make
sure that the amplifier is disconnected from the mains before you set the operation mode switch on the rear panel
to bridge. Connect your speakers to the red mono bridged speaker socket.
CAUTION! Before switching on your amplifier, please refer to the explanations under "10. Operation". Adjust the
level with the gain control CH-1 on the front panel.
