OPERATION

Distortion Control

(Linear-Phase; no delay) is a phase-linear crossover whose upper
L N D

band is derived by subtracting its lower band from the crossover's input. When the
upper and lower bands have the same gain, their sum is perfectly flat with no phase
rotation. However, when the upper and lower bands have different gains, peaks and
dips appear in the frequency response close to the crossover frequency. It is useful if
you need a crossover with low delay and no phase distortion when flat. Its downside
is the possibility of coloration when the gains of the two bands are widely disparate.

except as noted in the descriptions on the following pages.

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
