UNCTIONAL DATA
= Defeat mode
If no effects are applied
(defeat
mode),
the Sound Enhancer
will cause
a
minor time lag of between 1 and 3

a
Sample rate
conversion
The
Sound Enhancer is equipped
with
a TDA 1373 Sample Rate
Converter, which
supports
20-bits. Any input sample
rate
between 15
and 50
kHz
can be converted to 48 or 44.1 kHz.
msQuantization noise imaging
Quantization Noise
Imaging
is a form of inband noise shaping which
moves the quantization
noise outside the audible
range. If

active
the o u t p u t
is 16-bit with this particular form of in-band noise
shaping. Although the Sound Enhancer operates at 24-bits internally
and the
A/D
conversion is 20 bits this does

automatically imply
20-bit resolution

= Scratch Suppression
The sensitivity control setting allows an optimal adaption
for
the
source
material involved. Because the detection path works on the differential
of
the
input signals, the sensitivity setting m a y be much
lower for a
mono
recording than, e.g. for amicrophone based stereo one. The
Sound
Enhancer
makes it possible to post processa digital recording of
a
scratched
(vinyl)
record
in order to optimize the parameters.
The de ‑
click function
generates a
small
time delay of
about
10 ms.
