This speaker system is capable of standard connections and bi-wiring connections. Before making connections, make sure
that the amplifier is switched off.

Connections
Connect the screw-type input terminals at the rear of the
speakers to the speaker output terminals of your amplifier
with the speaker cables.
Connect the (+) terminals on both the amplifier and the
speakers using one side of the cable. Connect the (–)
terminals on both components using the other side of the
cable.
Connect one speaker to the left (marked L) terminals of your
amplifier, and another speaker to the right (marked R)
terminals, making sure not to reverse the polarity (+, –). If
one speaker is connected with reversed polarity, the sound
will be unnatural and lack bass.
Procedure:
Loosen the terminal knob.
Remove approx. 10 mm insulation from the speaker cable
and insert the bare wire end properly into the terminal hole.
Tighten the knob.
Test the security of the connection by tugging lightly on the
cable at the terminal.
Note
Do not let the bare speaker wires touch each other as this
could damage the speaker and/or the amplifier.

Bi-Wiring Connections
This speaker system is capable of bi-wiring connections. To
connect the speakers to the output terminals of the amplifier,
two pairs of cables for each of woofer and 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.
To utilize bi-wiring connections, remove the short bars from the
terminals first, and then connect the woofer and tweeter to the
amplifier separately using two pairs of cables.
Note
For bi-wiring connections, use the same type of cable for
both the woofer and tweeter, making sure to match the
polarity.
