Calibrating the system

Introduction

We recommend that you perform the calibration procedure using 

the MSR+ and from the listening position.

As you run the calibration procedure the name of each calibration 

test is shown on the front-panel display, followed by the 

parameters adjusted in the test.

Each calibration test uses a test signal designed to give the best 

results. 

Using a  Sound Pressure Level meter

Although you can perform the calibration procedure by ear, it is 

recommended that you perform the tests using a Sound Pressure 

Level meter. These are available fairly cheaply from Tandy/Radio 

Shack, or your Meridian dealer may be able to lend you one.

Set the Sound Pressure Level meter to C weighted, and Slow. Take 

readings with the meter at the listening position, pointing vertically. 

You should hold the meter with an outstretched arm to minimise 

reflections from your body.

You can choose to display and enter distances in either feet and 

inches or metres.

To help you to set up the installation to give the best possible sound with any particular 

combination of associated equipment, the G61 Digital Surround Controller includes a built-in 

 calibration  procedure.

This calibration procedure uses test signals to present a series of sounds, which you use to 

adjust certain aspects of the system to their optimum settings.

You should use the calibration procedure the first time you set up the system, and whenever 

you want to check the calibration, such as after changing the layout of the room.
