Configuring the digital surround processor using a computer
Speaker protection
Because of the high bass levels that 5.1 materials are capable of
reproducing, the digital surround processor allows you to set up
automatic protection of each full-range speaker or subwoofer.
A setting of Max corresponds to no protection, and 0
corresponds to full protection. By default any Meridian DSP
loudspeakers in your system are set to Max, as these include
built-in protection.
You can use SizeCalc to help you calculate the correct value for
your speakers:
● Click the Size calculator button to display the SizeCalc
window:
● Specify the number of bass units in each speaker (woofers),
the size of each unit, and the design of the speaker.
To specify the speaker sizes
● Once you have specified the speaker layout for you system,
click the Sizes tab to display the Sizes page of speaker
settings:
This allows you to set up speaker protection for the 5.1 sources,
the type of each subwoofer, and peak level limiting.
