<Bi-wired connections>
Before connecting the speaker cable, you must remove the jumper cable.
To connect the speaker to the
output terminals of the amplifier,
two pairs of cables for each of the
woofer and the tweeter are used
instead of standard connections.
This type of connection decreases
the modulation distortion caused by
electric resistance of the cables and
driving current of the speakers.
Consequently, purer sound quality
can be expected.
