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.
