A Word Of Advice; Acoustic Feedback - Infinity Micro II Owner's Manual

OSITIONING OF THE UBWOOFER
The performance of the Micro II subwoofer is directly related to its position in the listening room.
Moving the subwoofer even as little as an inch or two can sometimes make a significant difference
in the way it sounds. If bass response is judged to be light, move the subwoofer closer to a corner.
The corner enhances the subwoofer' s ability to couple to the room, thus creating more bass. If bass
response is judged too heavy, move the subwoofer away from the wall or corner. The subwoofer
does not have to positioned between the two satellites for best overall sonic balance. It may be
placed wherever it sounds best. Low frequencies are nondirectional, which means you can place
the subwoofer either in the middle or to the left or right of the satellites and obtain optimum bass
balance. Experimenting with positioning the subwoofer in several different locations will reveal
which position yields the optimum results.

MPORTANT
The subwoofer may be mounted vertically or horizontally, but do not mount it so the port faces
the floor. The port must remain unobstructed for proper performance.

ORD OF DVICE
It is not advisable to operate the subwoofer (and satellites) with the tone controls of your stereo
system set to maximum boost. In fact, it is always good practice to keep the tone controls set to
reasonable boost levels because excessive bass and treble can damage your satellites as well as the
subwoofer.
The volume-control setting on your stereo preamplifier, receiver or integrated amplifier is not an
indication of the overall volume level of your system. The one important consideration is the loud-
ness level at which the system can be played, regardless of where the volume control is set.
Always turn down the volume when changing a record or switching inputs from AM to FM, phono
or CD operation. Excessively loud transients (loud pops and clicks) can damage your speakers.
Whenever changing plugs, cables, etc., always turn off your system. This will prevent transients
from reaching your speakers and electrical energy from reaching you. Keep electrical connections
out of the reach of children.

COUSTIC EEDBACK
Acoustic feedback is created when sound waves from speakers reach a phono turntable and are fed
back through the phono pickup to the power amplifier. It is a neverending cycle that can cause dis-
tortion across the entire audio band. To avoid acoustic-feedback problems, place your turntable on
a heavy, solid support as far away from the speakers as possible. Isolating the turntable with special
rubber mounts sometimes reduces this form of distortion.
