The decoder employs control signals derived
from the signal outputs rather than the inputs,
that is, using feedback analogous to and
output-controlled limiter. This leads to
tighter tolerances, excellent crosstalk
figures, and improved dynamics. It gives good
performance on matrix-encoded sources and
very pleasing results on unencoded two-channel
material. The paper discusses their principles
and their benefits.
