First Time Setup, Measurement Points | Onkyo HT-SP904 specification

First Time Setup

This section explains the settings that you need to make before using the AV receiver for the very ﬁrst time.

Automatic Speaker Setup (Audyssey 2EQ)

With the supplied speaker setup microphone, the Audyssey 2EQ function can measure the number of speakers con- nected, their sizes, crossover frequencies, and distances from the listening position, and then calculate the optimal speaker settings for your listening environment.

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

Measurement Points

To create a listening area in which several people can enjoy home theater simultaneously, the Audyssey 2EQ function takes measurements at three points within the listening area:

AFirst measurement point

This is the center point of the listening area, or the listening position if it’s just one person.

BSecond measurement point

The right side of the listening area.

CThird measurement point

The left side of the listening area.

The distances between points 1 and 2 and points 1 and 3 must be at least 1 meter.

From the examples below, choose the listening area that best matches yours and place the microphone accordingly when prompted.
