Read the following before connecting your speakers:
• Turn off your amp before making any connections.
• The nominal impedance of these speakers is 6
Ω
. Use
only an amp that supports this impedance.
• Pay close attention to speaker wiring polarity. Con-
nect positive (+) terminals to only positive (+) termi-
nals, and negative (–) terminals to only negative (–)
terminals. If the speakers are wired incorrectly, the
sound will be out of phase and will sound unnatural.
• Be careful not to short the
positive and negative wires.
Doing so may damage your
amp.
■ Connecting the Speaker Cables
Threaded inserts for 5 mm machine screws are provided
on the rear and buttom of the speaker for wall-mounting
with commercially available speaker mounts and brack-
ets. Refer to the manual supplied with your mounts or
brackets for installation details.
Note:
The portion of the screw that goes into the speaker’s
threaded insert should be between 5 mm and 9 mm
long.
The speaker can handle the specified input power when
used for normal music reproduction. If any of the fol-
lowing signals are fed to them, even if the input power
is within the specified rating, excessive current may
flow in the speaker coils, causing burning or wire break-
age:
1. Interstation noise from an untuned FM radio.
2. Sound from fast-forwarding a cassette tape.
3. High-pitched sounds generated by an oscillator, elec-
tronic musical instrument, and so on.
4. Amplifier oscillation.
5. Special test tones from audio test CDs and so on.
6. Thumps and clicks caused by connecting or discon-
necting audio cables (Always turn off your amplifier
before connecting or disconnecting cables.)
7. Microphone feedback.
• The speaker contain strong magnets, so do not put
magnetic or iron objects such as screwdrivers close to
them. If you do, the object may be attached to the
magnets, causing personal injury or damage to the
diaphragm.
Connecting the Speakers
1 Strip the insulation from the
ends of the speaker cables,
and twist the bare wires tightly.
2 Use the cables to connect speaker’s input
terminals to the corresponding speaker
output terminals on your amp.
To make a connection, while
pressing the terminal lever,
insert the wire into the hole, and
then release the lever.
Make sure that the terminals are
gripping the bare wires, not the insulation.
