Input Connections
Connecting the amplifier to your source equipment is sim-
ple. 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 unbal-
anced 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 be-
tween the interconnection cable and the input jack. Be care-
ful 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.
NOTE: There is an XLR pin assignment diagram located just above the
binding posts for Output-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.
Speaker Connections
To assure that the high quality signals produced by your
amplifier are carried to your speakers without loss of clari-
ty 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,
multi-strand copper with a gauge of 14 or less. In specify-
ing 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.
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 connec-
tions 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 termi-
nals, 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, us-
ing the appropriate speaker hook-up icons for your system's con-
figuration. Using your fingers, tighten to obtain a positive con-
tact.
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. Re-
member to connect your negative, or black wire, to the matching
terminal on the speaker. The positive, or red wire, should be con-
nected to the matching terminal on the speaker.
NOTE: While most speaker manufacturers adhere to an in-
dustry convention of using red terminals for positive connec-
tions and black terminals for negative, some manufacturers
may vary from this configuration. To assure proper phase
connections, and optimal performance, consult the identifica-
tion plate on your speaker terminals, or the speaker's manu-
al to verify polarity. If you do not know the polarity of your
speaker, consult the speaker's manufacturer for further in-
formation.
