Signature 1.5
To ensure that the high-quality signals produced by the
1.5 are carried to your speakers without loss of clarity or
resolution, we recommend that you use high-quality
speaker cable. Many brands of cable are available, and
the choice of cable may be influenced by the distance
between your speakers and the amplifier, the type of
speakers you use, personal preferences and other factors.
Your dealer or installer is a valuable resource to consult in
selecting a proper cable for connections between your
amplifier and speakers.

Cables run inside walls should have the appropriate
markings to indicate listing with the appropriate safety
agency standards that may be required in your area.
Questions about running cables inside walls should be
referred to your installer or a licensed electrical contractor
who is familiar with the applicable building or electrical
codes in your area.

Next, loosen the knobs of the speaker output terminals far
enough so that the cap moves back on its threads past the
holes at the rear of the terminal. Making certain that you
observe the correct polarity for the type of system being
installed (Stereo or Bridged Mono), pass the exposed wire
through the hole until the wire is visible from the bottom
end. Holding the wire in place, twist the cap back so that
the connection is secured. Do not overtighten or use tools,
as this may damage the plastic terminal cap or break the
delicate wire strands and decrease system performance.

Important Note: When making speaker wire
connections, be certain that none of the strands from one
lead touch any other lead. This will cause a short circuit
and may damage your amplifier or speakers. Damage
from short circuits caused in this manner is not covered

Connections may also be made using spade lugs or
standard 4 mm OD banana plugs. Before using a banana-
type jack, make certain that the plastic screw caps on the
1.5 are firmly tightened by turning them clockwise until
they are snug against the chassis. This will ensure that the
maximum surface area of the plug is in contact with the
jack. Once the wire has been attached to the banana
plug following the plug manufacturer’s instructions,
simply insert the banana plug into the hole provided on
the rear of the colored screw caps on the terminal posts.
