Speaker Connections
Correct polarity connections are important to maintain proper
speaker phasing. When speaker phasing is correct, all speakers
move in and out at the same time, preserving the imaging of the
program material. Out-of-phase connections mean that some
speaker cones will be moving in, while others move out. This will
cause indistinct or confused imaging, and muddled and cloudy
sounds. To avoid incorrect phasing or polarity, be certain to use wire
that has distinct markings, colors, stripes, wording, or grooves on
each side of the speaker cable. 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. 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 connection 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 manufacturer’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 hookup icons for your system’s configuration.
Using your fingers, tighten to obtain a positive contact.
When using banana plugs, connections may be made by simply
inserting the jack affixed to your speaker wire into the hole pro-vided
on the rear of the colored screw caps on the binding posts. Before
using banana type jacks, make certain that the plastic screw caps
are firmly tightened down by turning them in a clock-wise direction
until they are snug against the chassis. This will insure that the
maximum surface area of the plug is in contact with the jack. Be
certain to observe proper polarity.
Run the cables to the speaker locations. Do not coil any excess
cable, as this may become an inductor that creates frequency
response variations in your system. Finally, connect the wires to the
speakers, again being certain to observe proper polarity.
Remember to connect your negative, or black wire, to the matching
terminal on the speaker. The positive, or red wire, should be
connected to the matching terminal on the speaker.
While most speaker manufacturers adhere to an industry convention of using red
terminals for positive connections and black terminals for negative, some manufacturers may vary
from this configuration. To assure proper phase connections, and optimal performance, consult
the identification plate on your speaker terminals, or the speaker’s manual to verify polarity. If you
do not know the polarity of your speaker, consult the speaker’s manufacturer for further
information.

Connecting the amplifier to your source equipment is simple.
Using high-quality XLR cables or audio interconnect cables,
match the output channel designations on the rear of your
source equipment to the balanced input jacks or unbalanced
inputs jacks on the rear panel of your amplifier that have the
same channel name. When making connections with RCA
type plugs or XLR connectors on interconnect cables, make
certain to gently, but firmly, insert the plug into the jack and
make sure that they are firmly seated. Loose connections can
cause intermittent sound and may damage your speakers.
Some quality plugs may be very tight, and it is important to
assure a proper connection between the interconnection
cable and the input jack. Be careful to match the type of input
you have decided to utilize on your amplifier with the same
type on your preamp or other source device. Do not mix
types, i.e. do not use an RCA type jack on one end and an
XLR connector on the other as this will defeat the output.
Once you have chosen the type of connectors and made the
connections, be sure that the small toggle switches located
between the RCA and XLR jacks are thrown toward the
connector being used. There will be no output if the toggle
switches are in the wrong position.
To assure that the high quality signals produced by your
amplifier are carried to your speakers without loss of clarity or
resolution, we recommend that you use high quality speaker
wire. Many brands of wire are available; the choice may be
influenced by the distance between your speakers and the
amplifier, the type of speakers you use, personal
preferences, or other factors.
Regardless of the brand or type of speaker wire selected, we
recommend that you use a wire constructed of fine,
multistrand copper with a gauge of 14 or less. In specifying
wire, the lower the number, the thicker the cable. 16 gauge
wire may be used for short runs of less than twenty feet. We
do not recommend that you use any wires with an AWG
equivalent of 18 or higher due to the power loss and
degradation in performance that will occur.
To connect the amplifier to your speakers, a pair of binding
posts is provided for each channel output. These posts will
accept bare wire, spade lugs or banana type plugs. If bare
wire is used for the connections, strip approximately 1/2 inch
to 3/4 inch of insulation from the end of each wire and
carefully twist the strands of each conductor together.
Be careful not to cut the individual strands or twist them off.
All strands must be used for optimal performance.
There is an XLR pin assignment diagram located just below the binding posts
for Channel 1. Make certain that the cables connectors you choose utilize the same
order of wiring to your preamp or other source device...they may be different. Failure to
ensure this continuity will result in a malfunction. Please consult with your dealer if there
is any doubt.
