Professional Surround Sound Tuning Kit Crestron
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.
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.
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.
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).
