4QUANTIZATION
NOISE IMAGING
Quantization
Noise Imaging
(Q.N.I.)
can be used independently of the
other effects.
Q.N.I.
improves the audio quality of digital audio source material by mov ‑
ing the quantization noise present in the digital signal to outside the
audible
frequency
range.
The main advantage is that the audio perfor ‑
mance,
especially of l o w level signals/recordings, can be improved. Q.N.I.
works for 20-bit and 18-bit recordings, but the benefit will be more
noticeable for 16-bit recordings, e.g. CD. For analog recordings, or 20-bit
digital recordings,
the
Q.N.1.
effect
will
have
little
benefit.
To
activate
Quantization
Noise
Imaging:
a Press the
Q.N.I.
button.
The Quantization
Noise
Imaging
LED
in
the
push
button
comes on.
Q.N.1.
has
no adjustment, it is either on or off.
The
Q.N.I.
button has a toggle
action, so pressing it a
second time
disables
Q.N.1.
If
O.N.I.
is inadvertently
left on, it will n o t have any negative influence on
the audio.
