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.
