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,
