Connections
Make sure all equipment is turned off. When connecting the speakers, be sure to retain the correct polarity. Most speaker
cables will have (+) red sign for positive and (-) black sign for negative.
Connect the speaker cable to the positive (+) front-left speaker terminal on the amplifier and to the positive (+) terminal on the
front-left speaker. Connect the speaker cable to the negative (-) front-left speaker terminal on the amplifier and to the negative (-)
terminal on the front left speaker. Repeat the same step for the right – side front speaker. In the case that your speakers have
two sets of terminals on the back, either set of input terminals can be used as long as the shorting straps are in place. If you want to
bi-wire your speakers and if your amplifier is equipped with bi-wire output connection, remove the shorting straps and connect
each terminal to the associated terminal in your amplifier. The upper input terminals on the back of the speaker are connected to
the high frequencies and the lower input terminals are connected to the low frequencies.
Connect the speaker cable to the positive (+) center speaker terminal on the amplifier and to the positive (+) terminal on the center
speaker. Connect the speaker cable to the negative (-) center speaker terminal on the amp and to the negative (-) terminal on the
center speaker.
Connect the speaker cable to the positive (+) rear left speaker terminal on the amplifier and to the positive (+) terminal on the
rear-left speaker. Connect the speaker cable to the negative (-) rear-left speaker terminal on the amplifier and to the negative (-)
terminal on the rear-left speaker. Repeat the same step for the right-side rear speaker.
Position
THE FRONT SPEAKERS should be placed on each side of your TV or in front of your favorite listening position. As a general
guideline, the space from the speakers to the listening position should be 1.5 times the distance between the speakers. For
example, if your listening position is 9ft (2.7m) away from the speakers, the distance between the speakers should be 6ft (1.8m)
THE CENTER CHANNEL SPEAKER should be on top of or just above your TV.
THE REAR (SURROUND) SPEAKERS should be positioned either to the side of, or behind, your listening position. Typical
placement is on the side walls, slightly above ear level, about two-thirds of the way back from the front of the room. This allows
the surround speakers to aim directly at the listener, placing you in the middle of a five-speaker sound field.

Running time and cleaning
The performance of the speakers may change during the initial use due to storage and mechanical limitations. Please allow 15
hours of use for the temperature effect and mechanical parts to attain their intended design characteristics.
Make sure to turn all equipment off before cleaning. The cabinet only requires occasional dusting. Please avoid touching the
drive units.
