INSTALLING FEET
IL30 and IL40
Refer to Figure 3 as you perform the following steps:
1. Open each accessory pack and locate the following items:
four feet (with spike/round ends), four locking nuts, four
nylon domes and one wrench.
2. Lay each speaker on its side and locate the four threaded
holes on the bottom.
3. For carpets, screw the round end of a foot into each hole
and hand-tighten a nut onto each one. Leave a minimum of
5/8" of exposed spike. (On thicker carpets, you can increase
the length of exposed spike up to 1-1/8". ) For hard-surface
floors, screw the spike end into each hole instead and leave
5/8" of round end exposed.
4. Carefully flip each speaker upright to sit on its feet.
5. If needed, adjust the feet so each speaker is level and then
tighten each nut with the enclosed wrench.To protect hard
surfaces (e.g., wood floors), slip a nylon dome onto each
round end.

WIRING THE SYSTEM
IMPORTANT: Make sure all equipment is turned off before
making any connections.
For speaker connections, use a minimum # 16-gauge speaker
wire with polarity coding.The side of the wire with a ridge or
other coding is usually considered positive polarity (i.e., +).
NOTE: If desired, consult your local Infinity dealer about speaker
wire and connection options.
The speakers have coded terminals that accept a variety of wire
connectors.The most common connection is shown in Figure 4.
To ensure proper polarity, connect each + terminal on the back
of the amplifier or receiver to the respective + (red) terminal on
–
each speaker, as shown in Figure 5. Connect the (black)
terminals in a similar way. See the owner’s guides that were
included with your amplifier, receiver and television to confirm
connection procedures.
–
–
IMPORTANT: Do not reverse polarities (i.e., + to or to +)
when making connections. Doing so will cause poor imaging and
diminished bass response.

BI-WIRING
The Interlude Series outer connection panel and internal dividing
network are designed so that separate sets of speaker cables can be
attached to the low-frequency transducer and midrange/high-frequency
transducer portions of this dividing network.This is called bi-wiring.
Bi-wiring can provide several sonic advantages and considerably more
flexibility in power amplifier selection.

1. Loosen the terminals and remove
strapping bars.

2. Insert the speaker wire for the
high frequencies into the top set
of terminals and tighten.

3. Insert the speaker wire for the
low frequencies into the bottom
set of terminals and tighten.

FINAL ADJUSTMENTS
Check the speakers for playback first by setting the system
volume control to a minimum level, and then by applying power to
your audio system. Play a favorite music or video segment and
increase the system volume control to a comfortable level.
NOTE: You should hear balanced audio reproduction across the
entire frequency spectrum. If not, check all wiring connections or
consult the authorized Infinity dealer from whom you purchased
the system for more help.
The amount of bass you hear and the stereo-image quality will be
affected by a number of different factors, including the room’s
size and shape, the construction materials used to build the
room, the listener’s position relative to the speakers, and the
position of the speakers in the room.
Listen to a variety of music selections and note the bass level.
If there is too much bass, move the speakers away from nearby
walls. Conversely, if you place the speakers closer to the walls,
there will be more bass output.
Nearby reflecting surfaces can adversely affect stereo-imaging
quality. If this happens, try angling the speakers slightly inward
toward the listening position until the desired effect is achieved.
CARE OF YOUR SPEAKER SYSTEM
Each Interlude Series cabinet has a wood-vinyl finish that
does not require any routine maintenance.When needed, use
a soft cloth, dampened with water only, to remove any
fingerprints or dust.
Clean the grille by gentle vacuuming.
NOTE: Do not use any cleaning products or polishes on the
cabinet or grille.
