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 significant safety haz-

ard.

WARNING: Always turn off the amplifier and unplug

the power cord before making any electrical connec-

tions.

Amplifier Operation

Before turning on the AT3300, ensure that all precau-

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. The switch

will dimly light up during the soft-start sequence. There

will be a couple clicks from the chassis, this is normal.

These are relays activating to pass AC to the large pow-

er transformers. After the turn-on process is complete,

the front panel switch will illuminate fully. During the

soft-start sequence audio will pass through the amplifi-

er modules, but full power will not be available. To

turn the unit off, press the Power button again.

NOTE: We recommend not playing audio during the

turn-on soft-start sequence.

Automatic On

Make certain that the connection to the controlling de-

vice is correct. Whenever the controlling device is

turned on, the amplifier will automatically turn on. You

may also hear a relay click as during start up. This is

also normal.

To turn off your amplifier, simply turn off the device

feeding the amplifier it's trigger signal. The amplifier

will automatically go into a standby mode in a few mo-

ments.

ATI Service Information

The AT3300 series does not contain any user servicea-

ble parts inside. If you suspect a problem that may re-

quire service assistance, contact us at support@ati-

amp.com, or by phone at 323-278-0001. It is important

that only an authorized service agent carry out any re-

pairs. This will assure proper service and preserve the

protection of your Limited Warranty. Keep your sales

slip or receipt in a safe place with this manual so that it

will be available to verify the purchase date, should you

experience a problem covered by out warranty.

Care and Maintenance

Cleaning

When the unit becomes dirty, wipe it with a clean, soft,

dry cloth. If necessary, first wipe the surface with a soft

cloth slightly dampened with a mild soapy water, then

with a fresh cloth dampened with clean water. Wipe

dry immediately with a dry cloth. Never use benzene,

thinner, alcohol or any other volatile cleaning agent. Do

not use abrasive cleaners, as they will damage the fin-

ished of the metal parts. Avoid spraying insecticide,

waxes, polishing agents, or any aerosol product near

the unit.

Since these amplifiers have fans to help keep things

cool, every once in while the inside of the chassis and

fans will need to be dusted and cleaned out. Power off

the amplifier and disconnect all cables before removing

the top cover. Remove the top cover and with a can of

compressed air or even a small electronics / computer

vacuum clean out the fans and the inside of the chassis.

A Few Words About Hum and Noise

Audible hum, or a discernable low frequency noise, is

one of the most common problems in audio/video sys-

tems. This hum, which may be present even when the

volume is at a low level, is usually caused by a problem

known as "ground loops". A ground loop occurs when

there is a difference in ground voltages between two or

more components that are connected electrically. This,

in turn, creates multiple current paths and causes the

low-level noise, or hum.

The growing sophistication and complexity of home

audio/video systems, and the increased number of com-

ponents used to create these systems has dramatically

increased the potential for the possibility of ground

loops. While it is natural to suspect that the components

in your system are the cause of the hum, in many cases

the cause may be due to other conditions. In particular,

cable TV connections from outside the house have be-

come a major source of hum.

In most cases, one of the following suggestions should

help you to solve a hum problem in your system. Please

try these steps in the sequence shown, proceeding from

one step to the next if the prior suggestion does not

eliminate the problem.
