Connecting Your Amplifier
cause indistinct or confused imaging, and muddled and cloudy sounds. To avoid
incorrect phasing or polarity, be certain to use cable that has distinct markings,
colors, stripes, wording, or grooves on each side of the speaker cable.
IMPORTANT NOTE: Make sure the negative (–) speaker output is
NOT connected to signal or chassis ground anywhere in your system.
Damage to the power amplifier may result. The speaker outputs on your
amplifier are true balanced outputs. Both the (–) and (+) terminals are
active outputs. Connecting either of these terminals to anything else
will activate the amplifier’s protection circuits and may cause damage.
Some subwoofers have separate inputs for left and right speaker con-
nections. If you use these, make sure the (–) inputs are NOT connected
together. If they are, use only one set of inputs (left or right).
When making connections to the amp and speakers, adhere to a consistent
pattern of using one side of the wire to the red terminals and the other
side to the black terminals. When using cable with markings on one side
only, traditional convention is to consider the marked side of the wire as the red,
or positive (+) connection, and the non-marked side as the black or negative
(–) connection.
Next, loosen the knobs of the amplifier’s speaker output terminals, far enough
so that the pass through hole is revealed. Note that one conductor of the speaker
cable should have no markings, and the other should have a red line, brand
name markings, a colored thread, or some other positive indication. Follow the
proper connection instructions for your system with regard to which terminals
are used. Once the connections are made, twist the cap back so that the con-
nection is secured, but do not over tighten or use tools, as this may break the
delicate wire strands and decrease system performance.
If you are using spade lugs, connect them to the speaker wire using the manu-
facturer’s instructions, and then loosen the caps on the speaker terminals. Place
lugs between the plastic cap and the back of the terminal. Be sure to observe
proper polarity, using the appropriate speaker hook-up icons for your system’s
configuration. Using your fingers, tighten to obtain a positive contact.
