This speaker system is capable of standard connections and bi-wired connections. Before making
connections, make sure that the amplifier is switched off.
CONNECTIONS
You need a commercially available speaker cable.
y
The size and/or material of a speaker cable affects on the
sound quality. Therefore, we recommend you purchase a
high-quality speaker cable to exert the performance of this
unit.
Connect the + terminals on 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 (L) terminals of your
amplifier, and another speaker to the right (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.
When using an amplifier with a rated output power
higher than the nominal input power of the speaker,
care should be taken never to exceed the speaker’s
maximum input.
The speaker may be damaged if certain sounds are
continuously output at high volume level. For
example, if sine waves from a test disc, bass sounds
from electronic instruments, etc., are continuously
output, or when the stylus of a turntable touches the
surface of a disc, reduce the volume level to prevent
the speaker from being damaged.
Please refer to the owner’s manual that came with
your amplifier or receiver.
How to connect:
1 Loosen the knob.
2 Remove 15 mm (5/8") of insulation from each end
of the cables, and twist the exposed conductors
together neatly and tightly, as shown below.
3 Insert the bare wire into the hole.
4 Tighten the knob and secure the cable.
5 Test the firmness of the connection by pulling the
cable lightly at the terminal.
Do not let the bare speaker wires touch each other as
this could damage the speaker and/or the amplifier.
Do not insert the insulation coating into the hole.
The sound may not be produced.
<Standard connections>
When connecting the speaker cable, leave the
jumper cables in place.
