Using the Automatic Speaker Setup

With the supplied calibrated microphone, Audyssey MultEQ® 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 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. Audyssey MultEQ can be used with Audyssey Dynamic EQ® and

Audyssey Dynamic Volume® (➔ pages 49, 50). Before using this function, connect and position all of your speakers.

Audyssey MultEQ offers two ways of measuring: the “Audyssey Quick Start” and “Audyssey MultEQ

Full Calibration”.

•“Audyssey Quick Start” uses the measurement from one position to perform the speaker setting only.

•“Audyssey MultEQ Full Calibration” uses the measurement from six positions to correct room response in addition to the speaker setting.

The more positions are used in measuring, the better the listening environment will become. We recommend using a measurement from six positions to create the best listening environment.

The Quick Start takes 2 minutes and Full Calibration takes about 15 minutes.

Total measurement time varies depending on the number of speakers.

Measurement procedure

To create a listening environment in your home theater that all listeners will enjoy, Audyssey MultEQ takes measurements at up to six positions within the listening area. Position the microphone at ear height of a seated listener with the microphone tip pointed directly at the ceiling using a tripod. Do not hold the microphone in your hand during measurements as this will produce inaccurate results.

■First measurement position

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

Audyssey MultEQ uses the measurements from this position to calculate speaker distance, level, and the optimum crossover value for the subwoofer.

■Second-sixth measurement positions These are the other listening positions (i.e., the places where the other listeners will sit). You can measure up to six positions.

Turning On & Basic Operations

Note

•Make the room as quiet as possible. Background noise and Radio Frequency Interference (RFI) can disrupt the room measurements. Close windows, televisions, radios, air conditioners, fluorescent lights, home appliances, light dimmers, or other devices. Turn off the cell phone (even if it is not in use) or place it away from all audio electronics.

•The microphone picks up test tones played through each speaker as Audyssey MultEQ Room Correction and Speaker Setup runs.

•Audyssey MultEQ Room Correction and Speaker Setup cannot be performed while a pair of headphones is connected.
