First Time Setup—Continued

Audyssey MultEQ® XT Room Correction and Speaker Setup

With the supplied calibrated microphone, Audyssey MultEQ XT automatically determines the number of speakers connected, their size for purposes of bass management, optimum crossover frequencies to the subwoofer (if present), and distances from the primary listening position.

Audyssey MultEQ XT then removes the distortion caused by room acoustics by capturing room acoustical problems over the listening area in both the frequency and time domain. The result is clear, well-balanced sound for everyone. Enabling Audyssey MultEQ XT allows you to also use Audyssey Dynamic EQ™, which maintains the proper octave-to-octave balance at any volume level (see page 97).

Before using this function, connect and position all of your speakers.

If Audyssey Dynamic EQ is set to “On”, Audyssey Dynamic Volume™ becomes available.

About Audyssey Dynamic EQ

Measurement Positions

To create a listening environment in your home theater that all listeners will enjoy, Audyssey MultEQ XT takes measurements at up to eight positions within the listening area.

■First measurement point

Also referred to as the Main Listening Position this refers to the most central position where one would normally sit within the listening environment.

MultEQ XT uses the measurements from this posi- tion to calculate speaker distance, level, polarity, and the optimum crossover value for the subwoofer.

■Second−eighth measurement positions

These are the other listening positions (i.e., the places where the other listeners will sit). You can measure up to eight positions.

The following examples show some typical home theater seating arrangements. Choose the one that best matches yours, and position the microphone accordingly when prompted.

Audyssey Dynamic EQ solves the problem of deterio- rating sound quality as volume is decreased by taking into account human perception and room acoustics.

Dynamic EQ selects the correct frequency response and surround levels moment-by-moment at any user- selected volume setting. The result is bass response, tonal balance, and surround impression that remain constant despite changes in volume. Dynamic EQ combines information from incoming source levels with actual output sound levels in the room, a prereq- uisite for delivering a loudness correction solution. Audyssey Dynamic EQ works in tandem with Audyssey MultEQ XT to provide well-balanced sound for every listener at any volume level.

About Audyssey Dynamic Volume

Audyssey Dynamic Volume solves the problem of large variations in volume level between television programs, commercials, and between the soft and loud passages of movies. Dynamic Volume looks at the pre- ferred volume setting by the user and then monitors

how the volume of program material is being per- ceived by listeners in real time to decide whether an adjustment is needed. Whenever necessary, Dynamic Volume makes the necessary rapid or gradual adjust- ments to maintain the desired playback volume level while optimizing the dynamic range.

Audyssey Dynamic EQ is integrated into Dynamic Volume so that as the playback volume is adjusted automatically, the perceived bass response, tonal bal- ance, surround impression, and dialog clarity remain the same whether watching movies, flipping between television channels, or changing from stereo to sur- round sound content.
