Meridian Audio 565 - Manual (Page 38)

Calibrating the system
34
We recommend that you perform the calibration procedure
using the Meridian System Remote 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. The on-screen display also
provides additional text explaining what to do, and these
displays are reproduced in the following sections for reference.
For information about setting up the on-screen display refer to
Video connections, page 9.
Each calibration test uses a test signal designed to give the best
results. For information about choosing an alternative test signal,
or one of the 565 inputs, see To select a different test signal,
page 44.
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, 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
vertical. You should hold the meter with an outstretched arm to
minimise reflections from your body.
