Using Basic Functions

Using the Automatic 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. Audyssey MultEQ XT can be used with Audyssey Dynamic EQ® and

Audyssey Dynamic Volume® (➔ page 52).

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

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

Full Calibration”.

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

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

The Quick Start takes 2 minutes and Full Calibration takes about 20 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 XT takes measurements at up to eight 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 XT uses the measurements from this position to calculate speaker distance, level, polarity, and the optimum crossover value for the subwoofer.

■Second−eighth measurement positions

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 XT Room Correction and Speaker Setup run.

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

Note

•The on-screen menus appear only on a TV that is connected to the HDMI OUT MAIN. If your TV is connected to other video outputs, use the AV receiver’s display when changing settings.

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