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.
