HF (High Frequency) Level Control
This control adjusts the relative level of high frequency out-
put to compensate for varying room acoustics or placement
behind a screen.
"+" is for absorptive, acoustically "dead" rooms (or when
the speaker is behind a movie screen). Use this position to
increase the HF level and restore the proper sparkle and liveliness to
the sound.
"0" is for rooms of average absorptive characteristics.
"-" should be used in rooms that are highly reflective, with hard floors
and exposed windows.
The setting of the HF control is mostly a matter of personal taste, so try it
in all three positions and see which one is preferred.
Boundary Compensation Control
Large room boundaries, such as floors, walls, and ceilings,
reinforce sound by acting essentially as acoustic "mirrors. "
When the speaker is mounted too close to the corner or a
wall/ceiling intersection, this sonic "reinforcement" often
results in an unnatural heaviness or coloration of the
sound.

If it's necessary to mount the speaker closer than 12 inches to the ceiling or
corner, you may find that by switching the Boundary Compensation control
"on, " the speaker sounds better. We recommend that you try the control in
both positions and see if it helps in your particular installation.
IR Knockout
There's an IR "knockout" plug in the upper right corner
of the front baffle. If you are using a multi-room con-
trol system, you can install a standard IR receiver in the
knockout hole.
