HX Pro Headroom Extension &
Dolby Noise Reduction Unit
∑Basic description of Dolby NR
During low-level program material,
Dolby NR acts to boost high-frequency
signals. During playback, these signals
are restored to their original level. Any
noise introduced in between these
processes (during recording) will be
reduced in playback. Dolby NR also
employs the principle of least treatment,
leaving high-level signals unprocessed
since the louder program material
serves to effectively mask any tape hiss.
Dolby C NR employs increased noise
reduction action which covers a lower
frequency range than Dolby B NR. It
provides up to an additional 10 dB of
noise reduction action.
∑Basic description of DOLBY HX PRO
Dolby HX Pro headroom extension is a
program-adaptive biasing technique
which can significantly improve the
quality of cassette recordings. HX Pro
improves a tape's ability to accept
signals at high levels. High frequencies
in the signal being recorded act as
additional bias. The HX Pro circuit
monitors the signal being recorded and
adjusts the record's bias level to
maintain constant effective bias. This
results in optimum bias at each point in
time. The usual effects of tape
saturation, including high-frequency
losses and distortion are significantly
reduced. HX Pro works only during
recording and the improvements will be
realized when playing back on any
cassette machine.
