DOLBY HX PR(l
Dolby HX
Pro
rs
an
"active
bias" technique
that
can improve the
quality
of audio
tape
recordings.
High-level
high frequencies
can
be
recorded
m0re accurately,
without
sacrificing
signal-to-noise
ratio,
while
such
side
effects of
tape
saturation as
distortion
are reduced.
What
ls
Bias?
Bias
is
a very
high-frequency
signal
generat-
ed
within
a
tape deck and
recorded
on the
tape simultaneously with
the
pr0gram
material.
This inaudible signal
allows a low
noise, low
distortion
recording
and flat
frequency response.
Different magnetic
tape
formuiations require
different
am0unts
of bias
for
0ptimum
performance.
lf
the
bias
level is
to0
high,
high-frequency
Maximum
0utput
Level
(M0
L)
decreases.
The
Problem
of
Self-Bias
Unfortunately, bias
level is
often influenced
by the signal
being
recorded.
The
high
f re-
quencies
contained
in
some
music act
as
bias.
This
unpredictable
source
of
bias
is
added
t0 the existing
bias,
resulting
in a
loss
of
high-frequency response.
As the high-
frequency
content of the
signal
increases,
the
ability
of
the
recorder
to
record
high
f requencies
(M0
L)
decreases.
This
pheno-
menon is
called self-biasing.
