SPEAKER CONNECTIONS
Connect the left-side loudspeaker to the left-channel speaker terminals and the right side
loudspeaker to the right-channel speaker terminals of this unit, take care to observe connect
(+) and (-) polarity. If the polarity of one speaker is reversed, the speakers will be out of
phase, causing a loss in bass response and unstable, irregular stereo imaging.
Double-check to make sure that both speakers have the same polarity.
It is recommended that you use high-quality, heavy gauge speaker cable with low
resistance. Designed specially for audio applications, using thin cable with high
resistance may impair sound quality and prevent the amplifier from delivering its full
potential.
The speaker cables for both channels should be approximately equal in length, as a
marked difference can result in improper left/right balance.
Speaker Polarity note
Be sure to observe speaker polarity(+,- leads) throughout your system. Getting them wrong
can result in missing bass, massive distortion, or blown speakers!
Left positive (+) terminal to left speaker positive (+).
Left negative (-) terminal to left speaker negative (-).
Right positive (+) terminal to right speaker positive (+).
Right negative (-) terminal to right speaker negative (-).
