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.

Left +0dB

After a short delay the display shows:

●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.
