Meridian Audio 565 - Manual (Page 40)

Calibrating the system

Levels
This test allows you to adjust the output level to each speaker
individually, and it follows the general guidelines from Dolby and
Lucasfilm. A Sound Pressure Level (SPL) meter can be useful at
this stage; ask your dealer for more information.
After a short delay the display shows:
Left +0dB
● Use the ] and [ keys on the Meridian System Remote to
move between each of the speakers in the layout in the
sequence: left, centre, right, side right, surround right,
surround left, side left, and subwoofers.
● Use
A and V to adjust the level of the speaker. Ignore any
tonal difference.
For correct THX reproduction you should adjust each speaker to
75dB SPL using an SPL meter. Even if your speakers are not
THX approved this setting is recommended.
Note that you cannot set the level of a subwoofer by ear,
because low-frequency noises sound quieter. To set the
subwoofer correctly either use an SPL meter, or set it by ear and
then reduce the subwoofer gain by 15dB to correct for human
hearing.
Digital or Meridian outputs cannot be set above 0dB. You will
therefore need to reduce the level of louder channels to match
them.
● When you have completed the Levels section press Store to
proceed to the next test.
