Installation and Connections

8

Signature 1.5

simply insert the banana plug into the hole provided on
the rear of the colored screw caps on the terminal posts.
Be certain to observe proper polarity.

Finally, run the cables to the speaker locations. It is highly
recommended that the length of cable connecting any
pair of speakers be identical. For example, make certain
that the cable length connecting left and right front or left
and right rear (surround) speakers is identical, even
though one speaker may be physically closer to the
amplifier than the other. Do not coil any excess cable, as
this may become an inductor that creates frequency
response variations in your system.

Connect the wires to the speakers, again being certain 
to observe proper polarity. Remember to connect the
negative or black wire to the matching terminal on the
speaker. Similarly, the positive or red wire should be
connected to the like terminal on the speaker.

Note:

While most speaker manufacturers adhere to an

industry standard of using black terminals for negative
and red ones for positive, some manufacturers may not
adhere to this configuration. To ensure properly phased
connections and optimal performance, consult the identi-
fication plate on your speaker terminals, or the speaker’s
manual to verify polarity. If you do not know the polarity
of your speaker, ask your dealer or installer for advice
before proceeding, or consult the speaker’s manufacturer.
