Speaker Cable

Always use the heaviest-duty (lowest gauge) speaker cable available. The terminals can
accommodate very thick speaker cable.

Maintaining Proper Polarity

It is very important to wire your speaker connectors consistently at each end of each
cable, in order to maintain proper polarity. All quality cables are manufactured with
clear markings to identify the different conductors – normally by color-coding,
printed markings, or textured ribbing on the cable's jacket material. Always make
certain to correctly wire your connections so that tip is connected to tip, and sleeve
to sleeve. Failing to do so will cause your speakers to operate out of phase, resulting
in significantly reduced low-frequency output from your system.

Rack Mounting Your Amplifier

The amplifier expels heat through the rear panel heat sink. When mounting in a portable
equipment rack, maintain adequate ventilation by making certain the front and rear
panels are not obstructed.
