• You can also use banana plugs for this connection. To do
so, you must first remove the caps from the terminal
posts.
3 Connect the other ends of the cables to the amp's
speaker output terminals (for more details, refer to your
amp owner's manual).
• After connecting the plugs, pull lightly on the cables to
make sure that the ends of the cables are securely
connected to the terminals. Poor connections can
create noise and interruptions in the sound.
• If the cables' wires happen to be pushed out of the
terminals, allowing the wires to come into contact with
each other, it places an excessive additional load on the
amp. This may cause the amp to stop functioning, and
may even damage the amp.
• When using a set of speakers connected to an amplifier,
you won't be able to obtain the normal stereo effect if the
polarity (
, ) of one of the speakers (left or right) is
reversed.
2 Insert a speaker cable into each of the terminal post
holes, then tighten the knobs.
Caution: when bi-wiring
Note that in this setup, connecting the cables with the
polarity reversed may seriously degrade the tone; refer to the
section "Connecting the cables" again and confirm that the
cables are connected properly.
3 Connect the matched pairs to the same speaker
terminals on your amp (taking care not to get the
polarity reversed).
Make sure to use the same type of cable for the low-fre-
quency and the same type for the high-frequency connec-
tions.
When bi-amping
Bi-amping is an even more powerful way of connecting your
speakers. Just as with bi-wiring, the input terminal short bars
are removed, but here the low-frequency terminals are
connected to a separate, dedicated low-frequency amp, and
the high-frequency terminals are connected to a dedicated
high-frequency amp.

Bi-wiring Connections
Bi-wiring requires two cables for each speaker, one for high
frequencies and one for low frequencies. Using separate
cables for the high end and low end improves the sound.
1 Loosen the cap knobs on the left input terminals and
remove the two short bars.
In this state, the low-frequency speakers and the higher-
frequency speakers are completely independent. Store the
short bars in a safe place for later use. The lower terminals
are for the bass, and the upper terminals are for midrange
and treble sounds.
