G61R Digital Surround Controller Installation Guide - Meridian

Speaker size
These tests allow you to determine the bass handling capability
of subwoofers and large analogue speakers. Once set, the digital
surround controller will limit the bass level to protect the speakers
from potential damage.
On starting the test the speaker sizes are set to zero to avoid the
possibility of damaging the speakers, and the display shows:
Press More for help
Sizes set to zero
ìî ïñ óòô öõú
The display then shows the first large analogue speaker; for
example:
Press More for help
Left Size 0
ìî ïñ óòô öõú
• Press A or V to adjust the size value for the speaker until it just
begins to distort distinctly, and then reduce the value by one.
• Press > or < to move between each of the speakers to be
adjusted.
This is the last test in the calibration procedure; see To complete
the calibration procedure, page 28.
