The Interlude IL50 and IL60 offer unprecedented flexibility for connecting the
system to any type of audio or home-theater system. Consult the table at right
to determine which system description most closely matches your own, then
follow the hook-up method corresponding to that system.
If none of these system configurations seem to match yours, consult your dealer
or Infinity customer service for direction on how best to hook up your system.
For methods 2, 3a, 3b and 4, make sure all bass-management features are
properly set. The Audio channels should all be set to “Small” or “High-Pass”
and the subwoofer set to “On.”

Final Positioning
After correctly connecting the loudspeaker and
verifying that both the subwoofer and main section
portions are playing, it is time to optimize the
system for your particular listening room.
Earlier, you placed the loudspeakers in their general
location. Finding the exact location for optimum
performance sometimes only involves moving the
speakers a few inches in any direction. We urge
you, therefore, to experiment with placement until
your speakers deliver their full potential. When the
speakers are moved inward (toward each other)
there is generally better focus of instruments and
vocalists; however, moving the speakers too close
together can reduce the spaciousness of the stage
effect and you may need to experiment with the
trade-off between focus and imaging. If your
listening room is larger than average and your
listening position is relatively far from the speakers,
wider placement of the speakers may be required.

Bass Optimization System
TM
(Cont.)
NOTE:It is important that you make the same adjustments to both loudspeakers.
Set the Bass Optimization System Bandwidth adjustments to a middle position (10 clicks from a
fully clockwise position) and set Level adjustments for a –6dB (8 clicks from a fully clockwise
position). Then,while the music is playing,sit in your favorite chair and have somebody else slowly
adjust the Frequency controls from fully clockwise to fully counter-clockwise. At a certain
frequency, you should hear the problem lessen and the overall bass performance improve. When
you are satisfied that you have found the best frequency, have your assistant vary the Levels
slowly up and down until you have maximized the improvement.If you have really keen ears, you
can also have the Bandwidth controls adjusted for maximum benefit.
While the Bass Optimization System allows the listener to fine-tune the bass response to sound best
in a particular room,some listeners don’t 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-Finder” to 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.
