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 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.

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 AC receiver or other audio

equipment. Connect the 3.5mm mini-plug from the

AT500NC 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.

Power Connection

Once all audio and system connections have been

made, connect the supplied power cord to the amplifier

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,

the front panel power switch will dimly illuminate and

pulse slowly. The amplifier is in the standby mode and

draws less than 1 watt from the wall outlet.

CAUTION: 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, CD players or cassette

decks. These cannot handle the high current draw of a power

amplifier. Using these outlets for a power amplifier is a sig-

nificant safety hazard.

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 excessive-

ly high inrush current.

Amplifier Operation

Before turning on the AT500

tions and warnings have been carefully reviewed and

adhered to. Damage to the amplifier caused by improp-

er operation, wiring and/or ventilation will not be cov-

ered under warranty and ATI will not be liable for any

consequential damage or loss.

After all connections have been made you are ready for

operation. First, turn on the source components and

processor in your system. It is always a good idea to

turn on your amplifier LAST. This avoids the possibil-

ity of any turn on pops or transients from other equip-

ment being amplified and sent to your speakers where

they may cause damage. Always start with a low vol-

ume level on your controller or preamp to avoid dam-

age to your speakers.

Manual On

Simply press the front panel power switch. There will

be a short pause from the time the power is turned on

until power is applied to the speakers. This is intention-

al, and protects your speakers from damage while the

amplifier stabilizes. The switch will stop pulsing and

the STANDBY LED will illuminate. After the turn-on

, ensure that all precau-
