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.
