The distortion control adjustments are common to the 2-band and 5-band structures

The bass clipper is embedded in the multiband crossover so that harmonics created
by clipping are rolled off by part of the crossover filters. The threshold of this clipper
is ordinarily set between 4dB and 6dB below the threshold of the look-ahead limiter,
depending on the setting of the L
you are basing your Advanced Control adjustments. This provides headroom for
contributions from the other four bands so that bass transients don't smash against
the look-ahead limiter, causing audible intermodulation distortion between the bass
and higher frequency program material.
Some 6300 users feel that the bass clipper unnecessarily reduces bass punch at its
factory settings. To accommodate these users, the threshold of the bass clipper is
user-adjustable. The range (with reference to the look-ahead limiter threshold) is
