right arrow near the bottom of the screen.
7. Calibration Complete
 When the Calibration Complete message appears, click Close in the lower
right corner of the window to exit the application.
8. Optional Adjustments
Sometimes users want to change the level of the center channel (for example, to
boost dialog) or subwoofer. This is optional and is not required most of the time but
if it is desired, adjustments to these or any other channels can be made by going into
Pro Sound Tools or PROCISE Tools and clicking on Speaker Adjustments. This
allows each speaker’s level to be adjusted individually.
NOTE: After completion, you can demonstrate the improved performance of
Audyssey™ Room Tuning from the AMS or PSPHD front panel. On the AMS, go to
the Audyssey Configuration menu by selecting Theater, More, Tools and
Audyssey. On the PSPHD, press SETUP, then select Audyssey MultEQ. This will
allow an A/B comparison of the Audyssey and non-Audyssey configurations. On the
AMS, the system will automatically default to the Audyssey configuration when this
menu is entered or exited. On the PSPHD, the last setting will take priority.

Crestron Professional Surround Sound Tuning Kit
Professional Surround Sound
Tuning Kit
Introduction
Creston’s Professional Surround Sound Tuning Kit for the Adagio®Media System
and the PROCISE™ High Definition Professional Surround Sound Processor allows
custom installers use the Audyssey MultEQ®Pro PC application to bring Audyssey
MultEQ®XT sound equalization technology to high quality listening rooms.
Audyssey MultEQ®XT creates an optimum listening experience for every seat in
your theater using an ingenious equalization solution that automatically corrects the
time, level and frequency response for each speaker within the space.
Every listening room or home theater room will add colorations to the direct sound
coming from the loudspeakers. These colorations occur at both bass and treble
frequencies. In the bass, they are caused by the natural resonances (also called
modes) every room has. In the treble, they come from wall, floor and ceiling
reflections of the sound from the loudspeakers. MultEQ®Pro measures the sound
information throughout the listening area. Based on these measurements, MultEQ®
Pro calculates an equalization solution that effectively removes sonic colorations
caused by the interaction of sound from the speakers with the room, allowing the
speakers to attain their best possible performance.

Room EQ setup
When the Pro Sound Tools or PROCISE Tools application is launched, it will
provide a window for selecting the current system configuration (for example, 5.1,
6.1, 7.1 plus additional rooms, etc.). When a center speaker or subwoofer is not used,
un-check the Front Center Speaker and/or Subwoofer checkboxes as appropriate, in
order to enable “phantom” center and “phantom” subwoofer. The phantom setting
will route center and/or subwoofer information to the main speakers.
Any subwoofer low-pass filter should be defeated or set to the THX setting
(sometimes called “LFE input”). If the subwoofer low-pass filter cannot be defeated,
set it to its maximum frequency. Any subwoofer gain settings should be set to their
nominal position or at 12 o’clock on a conventional level control. Also, if the
subwoofer has any sort of auto standby or sleep mode that turns the power to the
subwoofer off after it does not receive any signal for some period of time, please
disable this mode. This will ensure that the subwoofer is always on, which is
important when taking measurements. The subwoofer may be set back to auto after
measuring is complete.
Click Room Equalization Setup… to begin the process.
NOTE: If you have not already done so, the application will prompt you to install
the special file for the microphone that came with your Professional Surround Sound
Tuning Kit.

The serial number on the microphone setup file should match the one printed on the
microphone.
Click the forward arrow to proceed to the “Measurement” screen.
Measurement
“Measurement” Screen
The microphone should be positioned as far out from the stand as possible to
minimize the effect of stand reflections.
NOTE: You must place the microphone in a vertical position with the capsule
facing the ceiling for all measurements. Refer to illustration on page 3.
Quiet the room as much as possible. Background noise can disrupt the room
measurements. Turn off cell phones, televisions, radios, air conditioners, fluorescent
lights and other devices or home appliances. Close any open windows.
Refrain from talking and do not sit or stand directly between any of the speakers and
the microphone during the room measurements. Each speaker will emit a series of
test signals during the measurements and your body and background noise can
disrupt the microphone’s ability to properly record the room response to the test
signal.
Position 1 Measurement
For the Position 1 measurement, place the microphone at the primary or most central
listening location. The height should be the ear height of a listener seated at this
position.
NOTE: It is important to have the microphone in the primary listening position for
the first measurement. Every position measurement will record the room’s frequency
and time response but Position 1 also detects the absolute polarity of each speaker,
calculates the exact distance (within a half inch) for setting delays and determines
levels (within half a dB) for each speaker. The speaker type, distance, level, filter

characteristics and crossover frequency from the Position 1 measurement are
displayed later on the “Detection Results” screen (refer to “Detection Results” which
starts on page 11).
Press the Measure button. The Audyssey test signal will play a series of 10 “chirps”
through each channel. The name of the speaker being measured will be indicated
under the status bar while the test signal plays.
“Measurement Screen” (Showing Position 1 Progress)
After the application is finished playing the 10 chirps through each channel, the
application will transfer each channel’s measurement (this takes several seconds).
Click Undo Last if you want to erase your previous measurement.
Click Clear All at any time to erase all your position measurements and go back to
Position 1.
The Load Measurements and Save Measurements buttons allow you to start the
measurement procedure and return to it at a later time to continue, without losing any
measurements already taken. Press Save Measurements to save the current
measurements. Press Load Measurements to retrieve measurements already taken.
NOTE: When loading previously taken measurements, ensure the configuration
matches the current one. For example, loading a 5.1 channel measurement file into a
7.1 channel setup will result in two of the channels being undetected. Loading a 7.1
channel measurement into a 5.1 setup will result in the last two channels being
ignored.
Additional Position Measurements
Move the microphone to another listening position and press the Measure button
again. Repeat the process for all listening positions in the room. You will need to
measure a minimum of three positions before you can continue. The
recommendation is to measure a minimum of eight positions for typical rooms.
Stagger the height of the microphone by a few inches from location to location to
account for different listener heights.
Operations Guide – DOC. 6565C Professional Surround Sound Tuning Kit •9

Professional Surround Sound Tuning Kit Crestron
NOTE: A minimum of three measurements is required. You will not be able to
continue to the next screen in the application until the third measurement is
complete.
The larger the room, the more positions you should measure (the maximum is 32
positions). Make sure you measure only in positions where people will be located
while listening to the system (i.e. measuring in a far off corner where nobody would
ever listen will not be beneficial and may detract from the overall benefit within the
main listening area).
Audyssey MultEQ®Pro measures the absolute polarity of each individual
loudspeaker. If any of your speakers are wired out of polarity (i.e. +and –reversed),
the application will show you an error window that explains which loudspeaker(s) to
check. You may then check the polarity problem before continuing with the
application. It is recommended that you check for polarity problems by examining
the wire connections at the amplifier, speakers and any splices in the speaker cables.
NOTE: In some situations, such as when the rear speakers are dipolar radiators, the
program may show a polarity error even if the speakers are correctly wired. Correct
wiring should be verified by checking the connections at the amplifier, speakers and
any splices in the speaker cables.
Polarity Error Window
NOTE: After measurements are complete, Crestron recommends saving these (by
pressing the Save Measurements button) before proceeding to the “Detection
Results” screen. The program will show a standard window asking you to select a
location to save the new .amd file.
Click the forward arrow to finish the measurement process and continue to the
“Detection Results” screen.
NOTE: You can always return to the “Measurement” screen and measure more
positions by clicking the back arrow (the application will remember the last
measured position).

Crestron Professional Surround Sound Tuning Kit
Detection Results
“Detection Results” Screen
The “Detection Results” screen displays the Speaker Type, Distance, Trim,
Cutoff/slope and Crossover results derived from your Position 1 measurement (refer
to “Position 1 Measurement” which starts on page 8) and the recommended
Crossover derived from all of your position measurements.
• Speaker Type detects if the speaker connected to that channel is a satellite or
a subwoofer.
• Dist (feet) will automatically set the distance (delay) in the processor.
NOTE: Clicking on the heading for this column will change the display to
Dist (m) showing the distance in meters. Clicking the heading again will
change the display to show Delay (ms) showing the delay in milliseconds. A
third click will return the display to Dist (feet).
• Trim is displayed in dB. This number is not a dB SPL (absolute loudness)
number. It is an absolute trim and must be used as shown. When applied,
absolute trim gives reference level at the primary seat for volume set to
0dB. The Trim information will be automatically set in the processor.
• Cutoff/slope displays the filter characteristics applied to each speaker.
• Crossover is displayed in Hz. The Crossover information will be
automatically set in the processor. You can use the drop-down menus to
override the crossover settings that will be sent to the processor.
The Audyssey filter calculation is optimized based on your selected crossover
frequency setting in the Crossover drop-down menus. Crossover choices are listed in
descending order of preference to optimize satellite-subwoofer blending.
Only rarely should you ever choose the Large setting for the crossover. This setting
means the bass for that channel will not be sent to the subwoofer. Only in the
following situations, should you consider choosing the Large setting:
1. Your system does not have a subwoofer.
Operations Guide – DOC. 6565C Professional Surround Sound Tuning Kit •11

Professional Surround Sound Tuning Kit Crestron
2. Your satellite speakers extend as low or lower in frequency than your
subwoofer. Even in this case, however, you may not want to use Large
because your subwoofer probably has better power handling for the bass.
NOTE: Even if the Distance shown for the subwoofer is longer than the physical
distance, it is probably correct since subwoofers often have digital amps that delay
the signal.
Click the forward arrow to proceed to the “Target Sound Options” screen.
Target Sound Options
“Target Sound Options” Screen
On the “Target Sound Options” screen, choose which of the Audyssey target curves
you want to use by selecting the radio button next to the curve.
NOTE: To cover a wide range of room types, MultEQ®Pro currently provides a
selection of three target curves.
1. The High Frequency Roll Off 1 curve introduces a slight roll off at high
frequencies that accounts for the balance between direct and reflected sound
for a small to medium size rooms (room volume less than 2500 cu. ft.).
2. The High Frequency Roll Off2 curve introduces a slightly greater roll off at
high frequencies that restores the balance between direct and reflected
sound for medium to large size rooms (room volume between 2500 and
5000 cu. ft.).
3. The SMPTE 202M curve is an international standard for the high frequency
roll off applied in a typical 500-seat movie theater. It is appropriate for
professional mixing spaces and dubbing stages that must be calibrated for
film sound post-production. It can also be used in extremely large playback
spaces (room volume greater than 5000 cu. ft.).
