Connecting Your Amplifier
When making connections between any source compo-
nents and the amplifier, or when making connections to
any speaker, be certain that both the input devices and
the amplifier are turned off. To assure that there will be
no unwanted signal transients that can damage equip-
ment or speakers, it is always best to unplug all equip-
ment before making any connections.
Input Connections
Connecting the amplifier to your source equipment is
simple. Using high-quality audio interconnect cables,
match the output channel designations on the rear of
your source equipment to the input jacks on the rear
panel of your amplifier that have the same channel
name. The AT7000 amplifiers have Zone and Bus RCA
input connections on the rear panel. Use the toggle
switch to the right of each pair of RCA jack to select
the desired input for each channel. When making con-
nections with RCA type plugs on interconnect cables,
make certain to gently, but firmly, insert the plug into
the jack. Loose connections can cause intermittent
sound and may damage your speakers. Some quality
RCA plugs may be very tight, and it is important to
assure a proper connection between the interconnection
cable and the input jack.
Speaker Connections
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 select-
ed, we recommend that you use a wire constructed of
fine, multi-strand copper with a gauge of 14 or lower.
In specifying wire, the lower the number, the thicker
the cable. Wire with a gauge of 16 may be used for
short runs of less than twenty feet. We do not recom-
mend 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
"Phoenix" Style terminals is provided for each channel
output. These terminals will accept bare wire up to 8
AWG and handle up to 32 Amps of current. Strip ap-
proximately 1/2 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. Insert the bare wire into the terminal
block and tighten the screw.
AT7000 Manual
Correct polarity of connections are important to main-
tain 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 speak-
ers, 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 (+) con-
nection, and the non-marked side as the black or nega-
tive (–) connection.
Run the cables to the speaker locations. Do not coil any
excess cable, as this may become an inductor that cre-
ates frequency response variations in your system. Fi-
nally, connect the wires to the speakers, again being
certain to observe proper polarity. Remember to con-
nect your negative, or black wire, to the matching ter-
minal on the speaker. The positive, or red wire, should
be connected 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 identifi-
cation 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.
Power Control Connections
Your amplifier features a built-in remote turn-on sys-
tem that will automatically switch the amplifier on
when another device in the system is switched on.
Remote Turn-On Using Products
Equipped With a Low Voltage Trigger Jack
Press the front panel power switch on the amplifier so
that it is in the ON position. Then, using an accessory
cable with a 3.5mm mono mini-plug on each end, con-
nect the trigger-output jack on the rear of the source
device to the trigger input jack on the back panel of the
amplifier. When these connections are made, the ampli-
fier will automatically turn on and off with the trigger-
ing device. The trigger is compatible with a 3 - 24 VDC
steady state signal.
