Note: make sure the metal links are in place.
Bi-Wiring
Bi-wiring increases the flow of current and will usually improve the sound quality.
This method uses two pair of cables: one pair for the upper two terminals and one pair
for the bottom two terminals (see Fig. 2).
Connect the speakers to amplifier the same manner as you do single wiring.
You will need one pair of cable for each speaker in the system.
Note: remove the metal links.
Home Theater Application
Adding centre and rear speakers to the left and right channels will enhance the
surround effects of motion pictures. If you choose smaller models, an active sub-
woofer is essential for adequate bass reproduction.
On the back panel of your AV amplifier, locate the Front Speaker, Centre Speaker, and
Rear Speaker terminals.
Using the same method as connecting two channel stereo speakers, connect left and
right, centre, and rear speakers to the corresponding terminals on the AV amplifier.
Again, be sure to match the speaker cables to the appropriate terminals on the
components: (+) to (+) and (-) to (-) to ensure sufficient bass and clear imaging.
Adding a subwoofer to your home theater system will greatly improve bass
performance and provide fuller impact from motion pictures. We recommend C-11
subwoofer for smooth transition and configuration.
