INTERLUDE
The enclosure may be cleaned using a soft cloth, dampened with
water only, to remove fingerprints or to wipe off dust.
The grille may be gently vacuumed. Stains may be removed with
an aerosol cleaner, following its instructions. Do not use any
solvents on the grille.
All wiring connections should be inspected and cleaned or
remade periodically.The frequency of maintenance depends on
the metals involved in the connections, atmospheric conditions,
and other factors, but once per year is the minimum.
If a problem occurs, make sure that all connections are properly
made and clean. If a problem exists in one loudspeaker, reverse
the connection wires to the left and right system. If the problem
remains in the same speaker, then the fault is with the loud-
speaker. If the problem appears in the opposite speaker, the
cause is in another component or cable. In the event that your
Interlude loudspeaker system ever needs service, contact your
local Infinity dealer or Infinity directly at 1-800-553-3332 or
www.infinitysystems.com for a service center near you.

NOTE: It is important that you make the same
adjustments to
both loudspeakers.
Set the Bass Optimization System Bandwidth adjustments
K
to
a middle position (10 clicks from a fully clockwise position) and
set Level adjustments
J
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
9
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
J
slowly up and down until you have
maximized the improvement. If you have really keen ears, you
can also have the Bandwidth controls
K
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.
