Introduction
The Audyssey Sound Equalizer
TM
is a stand-alone hardware platform for custom installers to implement
Audyssey MultEQ
®
XT sound equalization technology in high-quality listening rooms using separate
amplifiers and preamplifiers.
The Sound Equalizer removes linear distortion (frequency response anomalies) caused by the interaction
of sound from loudspeakers within the room. This results in the playback of sound as it was intended,
without coloration, not just in one seat, but over a large listening area.
The installation of every Sound Equalizer requires professional calibration using the MultEQ
®
Pro PC
application and the Audyssey Installer Kit. Installers take the Installer Kit and a laptop to an installation site,
run the MultEQ Pro application, perform measurements, and transfer MultEQ XT filters from the laptop to
the Sound Equalizer. The steps for completing this installation are described in detail in this User Guide.
This MultEQ Pro User Guide will help explain all of the capabilities of the Sound Equalizer. The User
Guide has been designed to alternate between instructions that are of primary importance and information
that provides additional detail in smaller type.
The latest MultEQ Pro User Guides for the Sound Equalizer and other Audyssey Installer-Ready products
are available to registered Audyssey Installers through the Audyssey Installer Website,
http://www.audyssey.com/InstallerWeb. After signing in, click on Downloads in the left pane to view
available documentation and software from the Audyssey Website.
MultEQ Pro Setup Guide
The MultEQ Pro Setup Guide is included in the Installer Kit package. This guide
provides simple instructions for the installation and activation of the MultEQ Pro
application. Be sure to review this guide prior to installing MultEQ Pro on a laptop or
PC.
License Keys
The MultEQ Pro application is used to calibrate the Audyssey Sound
Equalizer, and other Audyssey Installer-Ready products.

installers and are valid for a limited time after purchase through the Audyssey
Installer Website.
Important Safety Precautions
Every precaution has been taken in the design of Audyssey MultEQ Pro and the Audyssey Sound
Equalizer to ensure they are as safe as possible. Please review the following safety information before
attempting to calibrate an Audyssey Sound Equalizer.
• Do not connect the Sound Equalizer to a power outlet that does not match the voltage input.
Verify the correct voltage level has been set by looking on the back of the unit above the power
connector. The marked square next to the voltage is the correct voltage. This voltage can be changed
if needed inside the box by changing switches on the DAE7-EQ PS board.
