Safety Instructions
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’s to be unused for a long period of time.
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
unit; or
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.

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
(servicing) instructions in the literature
7accompanying the appliance.
PRECAUTIONS:
Certain precautions must be taken in order to ensure proper
operation of your preamplifier-processor.
1. Never expose the unit to moisture
2. Never plug an input cable into the preamplifier while the
preamplifier 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 preamplifier. RF rectification
and/or hum may be created and could cause damage to the
loudspeakers. ATI will not be responsible for damage to
the loudspeakers, amplifiers or other related equipment
due to improper use of the equipment.
4. Avoid restricting the airflow around the unit. Good
airflow is necessary to help insure proper operation.
5. Do not stack other system components or any other
materials directly on top of the unit. The heat dissipating
system of the preamplifier depends on free flowing air
around the chassis.

System Setup
We urge you, at least the first time you set up your system, to
take the time and thoroughly follow each of the following
steps precisely. Even though this may take some time, it will
guarantee that your system will function properly and offer
the most rewarding results. If you “do it right” the first time,
future changes will be easier to implement.
Press the “MENU” button on the remote and the On Screen
Display (OSD) will appear as in the example below:
Using the Remote’s keypad, press the button corresponding to
what you want to setup. Selected function will be highlighted.
1. Speaker Size
Speaker size refers to your speaker’s actual frequency
response. For each channel, selecting “large” means that the
channel will be set to “full range” by the processor. Selecting
“small” means that the processor will filter out the low bass
from this channel and redirect this part of the signal to the
subwoofer. For some channels you may select “none” if you
don’t use a speaker for that channel.
2. Speaker Distance
You will need to set the distance, in feet, between your
listening position and each speaker. These settings automatically
calculate the accurate delay settings for each channel. Select
the number of the channel you wish to set, then press the
SELECT button to increase the distance. This setting is in
increments of 1 foot up to 30 feet, then start over at 1 foot.
3. Input Assignment
The default input assignment settings will be shown on the
screen. You can leave them as is or you may reassign any of
the 6 digital inputs. Select the number corresponding to the
input you wish to change then press the SELECT button. Each
time you press the SELECT button, the selected input will
scroll through each available digital input and then return to
the analog input. You may associate each analog input to any
digital input. Keep in mind that each analog input is labeled
on the back of the unit by its name, unlike the digital inputs
which are numbered 1 through 6.

Advanced Input Assignment: Analog Input Name Change
This set is available should you wish to rename any of the
analog inputs. Press the number of the input you wish to
rename then press the GUIDE button. A new menu on the
OSD page will appear. This menu will show the default and
actual name as well as five Xs. Use the cursor buttons to move
up, down, left or right to select and change letters and/or
numbers to create the new name. Press EXIT when done to
return to the previous menu.
4. Tuner and PAL/NTSC Settings
These settings are for the FM tuner OS video setting. Press
the number corresponding to your location for the tuner
setting. An “X” following the region indicates the current
setting. The “TV Setting” must be made according to your
location. NTSC for North America and PAL for most of Europe.
5. Bass Trim
You may adjust the bass level for each input independently.
Press the number representing the input you wish to change,
then press VOLUME UP or VOLUME DOWN to adjust the bass
in 1dB increments.
6. Calibration
You must calibrate the relative level of each channel to get a
proper surround sound presentation. For the most precise
calibration, you should use a sound pressure level (SPL)
meter. A loud pink noise tone will come from the selected
speaker when you press the associated button. Adjust each
channel’s output level to 75dB using the VOLUME UP or
VOLUME DOWN buttons. The levels should be adjusted from
the same listening position used in STEP2.
7. Compression
This feature allows you to compress the dynamic range of the
sound which may be helpful for low volume listening late at
night. Turning this feature off will permit full dynamic range.
When turned on, louder passages are softened and softer
passages are increased to maximize intelligibility of speech.
Use the SELECT button to toggle between on and off.
8. Status Display
Press the SELECT button to toggle between STATUS DISPLAY
ON and OFF. When turned on, an OSD appears for 2 seconds
each time you press a button. This OSD appears only when
using the “main out” composite or S-Video outputs. The
selected INPUT<SURROUND MODE and VOLUME LEVEL will
be displayed.
9. DVD Audio Full Range
This setting applies only to the 7.1 “analog pass through” input.
Use the SELECT button to toggle between “yes” and “no”.
When “yes” is selected, all signals present at the input will be
sent to the output and be affected ONLY by the VOLUME
control. When “no” is selected, the filters are defined by the
“SPEAKER SIZE” settings chosen in Step1. Channels set to
“large” will receive a full bandwidth signal while channels set
to “small” will have limited low frequency response (80Hz
filter). The analog filters will remove the low bass frequencies
from the signal and redirect it to the subwoofer.
