CONNECTION AND COMMISSIONING
16 Ohm. Using speakers with a different nominal
impedance will damage the amplifier. For each loud-
speaker (R: right or L: left), you will find on the back
oft he unit two loudspeaker terminals (21) (positive
+ and negative -), which are connected to one side
of a loudspeaker cable. There are similar connections
on the loudspeaker, as is the polarity. The other end
of the speaker cable assigned to the loudspeaker is
connected here. The loudspeaker cable must be con-
nected to the same terminals: the "+" marked termi-
nal on the amplifier must lead to the "+" marked
connection of the loudspeaker. The loudspeaker
cables are fitted without connectors. Remove an
approximately 1 cm long piece of insulation from
each end of the double cable. Twist the bare strand
to avoid mutual shorts. Rotate the screw of the loud-
speaker clamp counterclockwise to open the clamp
contacts and insert the bare wire end into the clamp
hole. Now turn the screw connection of the loud-
speaker clamp clockwise again in order to tighten
the wire in the loudspeaker clamp. You can check
that the cable is correctly seated by pulling it lightly.
In case you use pre-assembled speaker cables with
4 mm banana plugs, simply plug them into the bana-
na holder of the loudspeaker clamp. Make sure that
the polarity is correct.

for input channel AUX3 (USB/SD/BT/Tuner). The volu-
me can be set in steps of 0-30 and is an additional
volume control to the master volume knob on the
