WARNING: TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT EXPOSE THIS UNIT TO
RAIN OR MOISTURE.
Read all the safety and operating instructions before
connecting or using this unit.
All warnings on the unit and in this operating manual should
be adhered to.
All operating and use instructions should be followed.
Do not use this unit near water: for example, near a bathtub,
washbowl, kitchen sink, laundry tub, in a wet basement, or
near a swimming pool.
This unit should be installed so that its location or position
does not interfere with its proper ventilation. For example,
it should not be situated on a bed, sofa, rug, or similar surface
that may block the ventilation openings: or placed in a built-in
installation, such as bookcase or cabinet, that may impede
the flow of air through its ventilation openings.
The unit should be situated away from heat sources such as
radiators, heat registers, stoves, or other devices (including
amplifiers) that produce heat.
The unit should be connected to a power-supply outlet only of
the voltage and frequency marked on its rear panel.
The power-supply cord should be routed so that it is not likely
to be walked on or pinched, especially near the plug,
convenience receptacles, or where the cord exits from the unit.
Clean unit only as recommended in this instruction manual.
The power-supply cord of the unit should be unplugged from
the wall outlet when it is to be unused for a long period of
Care should be taken so that objects do not fall, and liquids
are not spilled, into the enclosure through any openings.
The unit should be serviced by qualified service personnel when:
A. The power cord or the plug has been damaged; or
B. Objects have fallen, or liquid has been spilled, into the
C. The unit has been exposed to rain, or liquids of any kind; or
D.The unit does not appear to operate normally, or exhibits a
marked change in performance; or
E. The device has been dropped, or the enclosure damaged.
To prevent electric shock, do not use the polarized plug with
an extension cord, receptacle or other outlet unless the
blades can be fully inserted to prevent blade exposure.
Please Read First
CAUTION: To reduce the risk of electrical shock, do not
remove the cover (or back). No user serviceable parts inside.
Refer servicing to qualified service personnel.
WARNING: To reduce the risk of fire or electric shock, do
not expose this appliance to rain or moisture.
The lightning flash with arrowhead, within an
equilateral triangle, is intended to alert the
user to the presence of uninsulated “dangerous
voltage” within the product’s enclosure that
may be of sufficient magnitude to constitute a
risk of electrical shock to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operation maintenance

The amplifier is a wideband design with substantial power
output capability. Certain precautions must be taken to
ensure proper operation.
1. Never expose the unit to moisture
2. Never plug an input cable into the amplifier while the
amplifier is turned on.
3. Never apply the “thumb test” (touching the “hot” lead of
the input cable with your finger) to the tip of the input
cable or input jack of the amplifier. RF rectification and/or
hum will be created and could cause damage to the
loudspeakers. ATI will not be responsible for damage to
the loudspeakers due to improper use of the equipment.
4. Under no circumstances should the output terminals of the
amplifier be short-circuited.
5. Avoid restricting the airflow around the unit. Good
airflow is necessary to help insure proper operation.
6. Be sure that the loudspeakers connected can handle the
output power of the amplifier at the loudspeakers rated
impedance. The warranty on the amplifier does not cover
damage to loudspeakers that have inadequate power
7. Do not stack other system components or any other
materials directly on top of the unit. The heat dissipating
system of the amplifier depends on free flowing air around
