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 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 industry convention of using red terminals for posi-
tive connections and black terminals for negative, some
manufacturers may vary from this configuration. To
assure proper phase connections, and optimal perfor-
mance, 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.
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.
Remote Turn-On
Using External AC to DC Power Converter
If your source device does not have a dedicated trigger
jack, it is still possible to activate the unit for automatic
turn on when a Switched Outlet is available on the rear
of the source device. To control the amplifier in this
fashion, you will need a small AC to DC power con-
verter, capable of delivering a 3.3 to 24 volt DC signal.
The DC voltage should terminate in a standard 3.5mm
type mini plug. This type of converter may be obtained
as a Power Adapter from many electronics retailers.
When installing, press the Main Power Switch on the
front panel of the amplifier in so that it is in the ON
position. Plug the AC adapter into a switched outlet on
the source device that will be activated when you wish
to have the amplifier turn on. This may be the switched
outlet at the rear of an AV receiver or other audio
equipment. Connect the 3.5mm mini-plug from the
AT3300 Manual
adapter to the trigger-input jack on the back panel of
the amplifier. The amplifier will now turn on and off
automatically, based on the status of the controlling
device.
AC Power Connections & Cords
The AT3300 amplifiers include 1 or 2 IEC60320 C20
power inlets, depending on channels count. We provide
1 or 2 power cords for the amplifiers, again depending
on channels count. For 120VAC operation, the supplied
power cords have a NEMA 5-15P wall plug on one
end. For 240V operation, the supplied power cords
have either a CEE 7/7 "Schuko" plug or a BS1363
plug. Use the included power cord(s) to connect the
amplifier to the AC source.
Once all audio and system connections have been
made, connect the supplied power cords to the amplifi-
er first, and then connect it to an AC power source.
Please make certain that the amplifier is turned off and
that the device connected to the remote trigger input is
off when connecting the power cord and plugging it
into an AC outlet.
When the power cord is plugged into the wall outlet,
and the main power switch / circuit breaker is in the on
position, the amplifier is in the standby mode and
draws less than 1 watt from the wall outlet.
NOTE: We recommend a direct connection to the wall
outlet. Placing a power conditioner in between the AC
source and the amplifier may reduce the overall power
available to the amplifier and reduce the output power
to drive your loudspeakers.
NOTE: For the 5-8 channel amplifiers, we also recom-
mend that each power cord be plugged into a separate
circuit. Separate circuits typically are connected to
different circuit breakers at the main service panel of
the building or sub-panel for the room/suite/theater.
NOTE: It is not recommended that you connect other
power amplifiers, or products with a high current
draw, to the same AC power circuit as the amplifier. If
this is unavoidable, the Ultra-Soft-Start circuitry of
your amp will prevent excessively high inrush current.
WARNING: Under no circumstances should the
"Earth" connection on the plug be cut, bent or in any
other way defeated as this may result in severe shock.
WARNING: Do not attempt changes to your household
electrical circuits by yourself, instead hire a licensed
qualified electrician.
WARNING: Do not plug the amplifier directly into the
"Switched Accessory" outlet of another device! These
outlets are intended for use with low current draw
products having a low current draw, such as tuners,
