System 920, 1200 and 2200 High Performance Loudspeakers
Boundary Compensation
Use this switch to adjust
the lower frequency output of the speaker to com-
pensate for the typical sound colorations caused by
placing the speaker close to a TV screen or building
it into a wall unit or cabinet. To set these controls, sit
in the prime listening position and have someone
switch between the compensation choices, using well
recorded dialogue or musical instrument recordings. Choose whichever
switch position sounds most natural and real to you.
NOTE:
Although these controls have been designed to compensate
for various acoustic room anomalies, we recommend that you try
them to hear the difference that they make in the sound of the sys-
tem. For any number of reasons, you may decide that you prefer them
set in a particular manner inconsistent with your room’s acoustics,but
which sounds best to you. Experiment. It will be worth it.
Dipole/Bipole Operation of the 2200 SR Speakers
In Dipole mode the 2200 SR’s produce
ambience with minimal localization (best
for most movies and video soundtracks),
and more localizable sound in the Bipole
mode (preferred for some music recordings). Switching between Dipole
and Bipole mode is easily accomplished using a toggle switch conveniently
located in the speakers rear terminal cup. Please note that the vast majority
of the time in movies and TV broadcasts the surround speakers are called
upon to reproduce the environmental sounds that are used as cues to help
get you immersed in the scene on the screen. Once the surround speakers
are properly positioned in the listening area, we recommend that you begin
with the dipole mode, as this usually delivers the most involving and believ-
able surround performance in most situations. However, as noted above, feel
free to experiment with both switch positions.

Bass Management
Some older surround sound decoders and receivers offer a choice of “Nor-
mal” or “Wide-band” modes for the center channel speaker. The Model
1200 and 2200 C are designed to be used in the Normal mode. Addition-
ally, digital processing multi-channel systems provide a Bass Management
menu, which typically requires you to select between “Small” or “Large”
speakers during system set-up. Since these systems have been designed
to work with a dedicated subwoofer, please set all the speakers in System
1200 or 2200 to Small.
If your receiver or processor has selectable subwoofer crossover frequen-
cies, we suggest using 80-100Hz for the 2200 and 100-120Hz for the 1200
and 920.

High Frequency Energy
This control changes
the tilt or roll-off slope of the tweeter. It has been
designed to help compensate for different room
acoustics. The Average position is intended for
rooms with a reasonable combination of reflec-
tive (hard) and absorptive (soft) surfaces. The
Reverberant position is designed for rooms with
an abundance of reflective surfaces like hardwood or tile floors, glass walls,
etc. It decreases the high frequency output of the speaker to reduce excess
HF energy that builds up in live rooms. The Damped position brings the
tweeter’s output slightly above flat response to compensate for overly absor-
bent rooms with lots of soft surfaces. Speakers in overly damped rooms can
sound dead and lifeless unless compensated.
