Wall-Mounting the Transmitter Module
NOTE: The customer is responsible for the correct selection and
use of mounting hardware (available through hardware stores) that
will ensure the proper and safe wall-mounting of the transmitter.
Step 1.
Insert the two M3 x 4 machine screws through the wall bracket and
into the rear of the transmitter module, as shown in the figure below.
Step 2.
Attach the transmitter module with wall bracket to the wall,
using suitable hardware and, if necessary, wall anchors.

OOM DAPTIVE
The Infinity R.A.B.O.S. ™ technology is a simple-to-use, yet
sophisticated, low-frequency calibration system. It is designed
to work in conjunction with the Infinity Classia PSW310W
powered sub.The subwoofer contains a parametric equalizer
that you will adjust as indicated by the R.A.B.O.S. test results.
By following these instructions, you will optimize the subwoofer's
response characteristics to complement the sub's environment.
This will dramatically improve the sound of your system.The
optimization process takes less than 30 minutes.
The Optional R.A.B.O.S. Kit Includes
the Following Components:
• Specialized Sound-Level Meter
• Test CD
• Instructions
• Measurement Templates
• Width Selector
• Adjustment "Key"
What R.A.B.O.S.Technology Does
The Test CD provides specially designed signals you will use
while performing measurements.The sound-level meter provided
is used to "acquire" the information needed for adjustments.
You will create a response plot on the R.A.B.O.S. Measurement
Template. Using the Width Selector, you will then determine the
appropriate equalizer settings.The Adjustment "Key"is used to
adjust the parametric equalizer built into the PSW310W.After
adjustment, the test sequence is repeated to confirm your settings.

ASS PTIMIZATION
The R.A.B.O.S. Goal
It is a fact of audio that what we hear at low frequencies is
determined as much or more by the listening room than by the
loudspeaker itself. Placement of the loudspeakers and listeners
and the acoustical characteristics of the room surfaces are all
important determinants of bass quantity and quality. In most
practical situations, there is little that can be done about this,
except for patient trial-and-error repositioning of the loud-
speakers and listeners. Usually, the practical constraints
of a living space and the impracticality of massive acoustical
treatment mean that equalization is the only practical solution.
Professional sound engineers routinely employ sophisticated
measurement systems and equalizers to optimize speakers to
the installation.This has never been practical for the home
audiophile.This is why R.A.B.O.S. technology was created. It
enables you to identify the dominant low-frequency response
characteristic of your room. Once you know the problem, the
R.A.B.O.S. system provides the tools needed to optimize the
low-frequency characteristics of the speakers to the room they
are in, exactly as the professional sound engineers do it.
Performing R.A.B.O.S.Tests
These instructions assume you have already installed your subwoofer
according to the information provided in the owner's guide. It is
also assumed that all equipment in your entertainment system is
interconnected properly and is in good operating condition.

Preparations
Before beginning R.A.B.O.S. tests, please check the following:
• Set R.A.B.O.S. System Selector ⁄ to the "On" position.
• Make sure all three R.A.B.O.S. controls
on the subwoofer are turned fully clockwise.
• Make sure the loudness contour (if any) on your receiver/
processor/preamp is turned off.
• Set the tone controls (Bass and Treble) to their center or
flat positions.
• Bypass all surround and effects features of your receiver/
processor/preamp or set to "Stereo Bypass. "
• If you are using a multichannel surround processor or receiver,
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."
You must have a CD player in the system. A CD player remote
control is quite convenient but not essential.
For best results, it is recommended that all major furnishings are in
place and that all doors and windows in the listening area are in
their normal positions.That is, if you normally listen to music with all
doors closed, then this is how they should be during this procedure.
Try to minimize ambient noise while running tests.Turn off all major
appliances and any air conditioning or furnace fans.These can
create significant subsonic noise that may be barely perceptible but
which can wreak havoc on low-frequency measurements.
