CONNECTIONS-
Stereo and Parallel Mode output
connections using binding posts
Connect each set of binding post outputs to its
respective loudspeaker.
Maintain proper polarity when hooking up loudspeak-
ers. Connect each red binding post (+, or positive) to
the red (or +, positive) terminal of each loudspeaker.
Connect each black binding post (-, or negative) to the
black (or -, negative) terminal of each loudspeaker. All
amplifiers and loudspeakers must maintain proper
connection polarity in order for bass response to be
optimum.
