CONNECTION OF THE LOUDSPEAKERS
If a loudspeaker is to be connected with "bi-wiring", both pairs of loudspeaker clamps may be used at
the same time. In contrast to connection of the loudspeakers with one loudspeaker cable each, with bi-
wiring a suitable loudspeaker is connected via two separate two-wire loudspeaker cables or one four-
wire loudspeaker cable to the pair of output clamps on the main amplifier. This doubles the cabling
required but for many combinations of loudspeakers and amplifiers this improves the sound quality.

If you are using ready made loudspeaker cables with 4 mm banana plugs, all you need to do is connect
the two plugs on each loudspeaker cable end to the two associated speaker connectors. At first installati-
on after unpacking the main amplifier it is neces-
sary to remove the small plastic security plugs
from the speaker connector holes (completely
remove the connector screw, remove the plug
and refit the screw again). Turn all connector
screws clockwise to fasten them.
If you want to use speaker cables equipped with spade lug connectors, every connector screw must be
opened by turning counter clockwise. After that, the lug must be moved under the screw head. Then, turn
the screw clockwise to fasten the lug to the connector. To avoid damages to the amplifier, make sure the
connection is tight and no bare metal from the cable lug connector makes contact with the rear panel or
with another terminal.
Before changing the system to bi-wiring, the metal bridges fitted to the
L
loudspeaker's double connector in normal operation must be removed.
Only loudspeakers with these bi-wiring terminals are suitable. Filtering
of the entire frequency range occurs in the now separated loudspeaker
crossover networks. One cable is to be connected to the loudspeaker's
sockets provided for the higher frequencies (treble) and the other with
the ones for the lower frequencies (bass) for each loudspeaker. Make
sure that the polarity is correct. Your specialist dealer will provide you
with advice and assistance.
