Instruction Manual
Front Panel Controls
The IW-30 LCR has three controls that help optimize the speaker's perfor-
mance regardless of mounting location or room acoustics.
High Frequency Level Control
This control adjusts the relative level of high frequency
output 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 High Frequency level and restore the proper sparkle and
liveliness to the sound.
"0/THX" 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.
Location Control
This control adjusts the relative level of the mid/high
frequency output to compensate for placement behind
a screen.
"0/THX" delivers the flattest output for placement behind a perforated
screen.
" - " reduces the mid-high frequency output slightly.
This control can also be used to adjust for different room acoustics.
Boundary Compensation Control
Large room boundaries, such as floors, walls, and ceil-
ings, 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 "rein-
forcement" 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.
"On" reduces mid-bass output to compensate for reinforcement of
nearby room boundary
"THX/Normal" yields flat response, with no mid-bass cut
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.
