CONNECTING THE MAIN SPEAKERS TO THIS UNIT
Connect the MAIN speakers to the MAIN speaker output
terminals of this unit. Make sure that the jumper bars between the
MAIN OUT and MAIN IN jacks on the rear panel are in place. It is
also possible to use an external power amplifier if more power is
desired. In this case, remove the jumper bars and connect the MAIN
OUT jacks to the INPUT jacks of a stereo power amplifier with a
stereo pin cable—making sure to connect the left and right channels
correctly. Connect the MAIN speakers to the speaker output
terminals of the power amplifier.
NOTE: If an external amplifier is used for the main speakers, it is
recommended to use the MAIN speaker terminals of this unit for the
rear effect speakers.
Connect the REAR EFFECT OUT jacks to the MAIN IN jacks with
the pin cord. This combination is highly upgraded and ideal for the
division of sound quality, because the rear channel output of the
Audio/Video system is equally important as the center channel.
