INTERLUDE IL25c,IL36c
Infinity Interlude Series
The Interlude series of loudspeakers continues Infinity’s
longstanding commitment to accurate sound reproduction.
Our proprietary Ceramic Metal Matrix Diaphragm™(C.M.M.D.)
drivers,precision dividing networks and rigid,heavily braced
enclosures combine to deliver uncompromised performance
in any stereo or multichannel home-theater system.The IL25c
and IL36c are the perfect center-channel loudspeakers to
complete any home-theater system.
If you suspect damage from transit,report it immediately to
your dealer.Keep the shipping carton and packing materials
for future use.
Placement
For best results,the IL25c or IL36c should be placed on top
of,or directly below,the television and aimed toward the
listening area (see Figure 1).
The IL25c and IL36c terminal cups each have an adjustable
foot to angle the speaker toward the listening position
(see Figure 2).

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.
To ensure proper polarity,connect each + terminal on the back
of the amplifier,receiver or television to the respective + (red)
terminal on each speaker,as shown in Figure 3.Similarly,
connect the – (black) terminals in the same way.Also,see the
owner’s guides that were included with your amplifier or
receiver to confirm connection procedures.

FIGURE 4
– Wiring diagram shows polarity connections for
one channel of a stereo or home-theater system.
IMPORTANT:Do not reverse polarities (i.e.,+ to – or – to +)
when making connections.Doing so will cause poor imaging and
diminished bass response.
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.Following the directions provided with your
receiver/processor,adjust the center-channel volume so that it
matches the output of the left and right speakers.
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.
