NOTE: Some receivers have a single subwoofer output (do not confuse
this with a single LFE output as described below). In that case, it is
recommended that you use a Y connector (not included) to maximize

OPERATION
Power On
Crossover Adjustments
Plug your subwoofers AC cord into a wall outlet. Do not use the
outlets on the back of the receiver.
Auto On/Standby
With the Power Switch in the ON position, the Power
Indicator LED will remain backlit in red or green to
indicate the On/Standby mode of the subwoofer.
Phase Control
The Phase Switch determines whether the subwoofer
speakers piston-like action moves in and out with the main
speakers, 0, or opposite the main speakers, 180. Proper phase
adjustment depends on several variables such as room size,
subwoofer placement and listener position. Adjust the phase
switch to maximize bass output at the listening position.
Adjust Gain
Turn on your entire audio system and start a CD or movie
soundtrack at a moderate level.Turn up the Subwoofer Gain
(Volume) Control about half way. If no sound emanates from
the subwoofer, check the AC-line cord and input cables. Are the
connectors on the cables making proper contact? Is the AC
plug connected to a live receptacle? Has the Power Switch
been pressed to the On position? Once you have confirmed
that the subwoofer is active, proceed by playing a CD, record or
cassette. Use a selection that has ample bass information.
Set the overall volume control of the preamplifier or stereo to a
comfortable level. Adjust the Subwoofer Gain (Volume) Control
until you obtain a pleasing blend of bass. Bass response should
not overpower the room but rather be adjusted so there is a
harmonious blend across the entire musical range. Many users
have a tendency to set the subwoofer volume too loud,
adhering to the belief that a subwoofer is there to produce lots
of bass.This is not entirely true. A subwoofer is there to enhance
bass, extending the response of the entire system so the bass
can be felt as well as heard. However, overall balance must
be maintained or the music will not sound natural. An
experienced listener will set the volume of the subwoofer so
its impact on bass response is always there but never obtrusive.
Alpha 1200s
To solve a problem, it helps to first identify whether you have one
and, if so, what it is. First, play a variety of music and films with
energetic bass sounds, like bass guitar, kick drum, keyboards,
etc. A kick drum should produce a tight thump
, not a flabby
boom. Bass melody or harmony lines should have notes that are
about equally loud. If some notes disappear, or stand out
because they are consistently too loud, there is a problem.
Disappearing notes have to be handled by moving the listening
position, or the loudspeakers, to slightly different locations.
Often, but sadly not always, this will be enough. Excesses in bass
tend to be most annoying, and energetic resonances that cause
boomy or lumpy bass can be truly aggravating over a period
of time. Infinitys Bass Optimization System can fix this.
So, the first step is to exercise your music collection, and listen
for low-frequency problems that crop up in several different
recordings. Something that only happens in one recording is
likely to be a problem in the recording it happens! If you
identify something that is consistently wrong, select a record that
shows it very clearly, and put your CD/DVD player into a repeat
mode (A-B repeat is especially helpful, because you can isolate a
short musical passage).
Preparations
While the Bass Optimization System allows the listener to finetune the bass response to sound best in a particular room, some
listeners dont have the skill or desire to adjust their system by
ear. In order to facilitate quicker and more accurate results,
Infinity has developed an optional test and measurement kit that
allows the user to perform a series of measurements and aids
him/her in properly setting the Bass Optimization System
controls. With the addition of this kit, the Bass Optimization
System becomes truly room-adaptive.The kit consists of the
following: a test CD, a sound-level meter that is specifically
calibrated for low frequencies, and something we call a Q-Finder,
a device to help find the width of the measured curve and,
finally, a measurement template. It works as follows.The listener
plays the tones from the test CD and records the relative output
level of each test tone, using the sound-level meter, on the
provided measurement template. After all the tones are complete,
the template contains a response curve for the frequencies
below 100Hz.The user simply notes the frequency of the largest
bass peak, calculates the correct amount of attenuation, and
uses the Q-Finderto determine the width of the curve.These
three values are dialed into the Bass Optimization System
controls located on the speaker.The entire process takes less
than twenty minutes.
If your dealer does not stock the Bass Optimization System test
and measurement kit, you may purchase it directly from Infinity.
U.S. residents can visit our Web site at www.infinitysystems.com
or call 1.800.553.3332. Canadian residents should contact their
dealer or call 1.800.567.3275.
