Connection
Connect only loudspeaker outputs of audio amplifiers to the loudspeaker terminals
AMP INPUT.
Connect only passive loudspeakers with impedance between 4 and 8 ohms to the
loudspeaker terminals SPEAKER OUTPUT.
Only use compatible speaker cables with a maximum cross section of 6 mm² or
speaker cables equipped with banana plugs.
Carefully check the relevant operating instructions of the devices that are to be
connected in regards to input and output wiring.
If these instructions are not observed, the device or connected devices (amplifier or
loudspeaker) may get damaged.
Switch off the power switch of the amplifier before connecting it and do not switch
the amplifier on again until you have made all the necessary connections and che-
cked them. Proceed in the same way when changing the circuit.
Make sure to introduce neatly the stranded wires into loudspeaker terminals to ex-
clude short circuits. Do not remove more than 6 mm of insulation from the speaker
line.
• Note the identification for connecting the loudspeaker terminals:
red
=
positive terminal
black
=
negative terminal
RIGHT =
right terminal
LEFT
=
left terminal
• Connect loudspeaker terminals SPEAKER OUTPUT PAIR 1 and PAIR 2 to the speakers.
• Connect loudspeaker terminals AMP INPUT to the loudspeaker outputs of the amplifier.
Operation
Loudspeakers connected can be switched on individually or at the same time using
the SPEAKERS selectors.
Speaker pair 1 is still running when both SPEAKERS selectors are in the OFF posi-
tion. This circuit protects your amplifier against damage during idle operation.
• Turn on your amplifier and start the music programme you want.
• Use the SPEAKERS selectors to select the desired loudspeaker pair (PAIR 1 or PAIR 2).
Position ON
>

Position OFF

• The SPEAKER PAIR 2 VOLUME controller is used to adjust the volume of speaker pair 2.
• The overall volume is adjusted with the volume control on the amplifier.
Care and cleaning
The power switch of the connected amplifier must be switched off during cleaning.
Never use abrasive cleaning agents, cleaning alcohol or other chemical solutions,
since these could damage the housing or even impair operation.
• Use a dry, lint-free cloth for cleaning.
• Otherwise, the product is maintenance-free and no other care is necessary.
