Recording
DSP (Digital Signal
Processing) Settings
The CD recorder is equipped with a function of
recording by applying digital equalizer, digital limiter,
or super bit mapping process. You can use these signal
processing functions when analog input (unbalance,
balance) or AES/EBU input is recorded.
(You cannot use these functions for COAXIAL and
OPTICAL input.)
The block diagram of processing is shown below.
The parameters set in the Setup menu are common to
each input signal, so the same settings are used after
switching input.
Using SBM (Super Bit Mapping)
To make recordings using the SBM filter, set the SBM/
LIMITER/EQ control to “SBM” or “SBM + L
EQ”.
SBM Filter
SBM Filter is a digital filter incorporating auditory
frequency characteristics to the noise-shape filter.
It achieves sophisticatedly sound recordings as delicate
and infinitesimal as equivalent to 20 bits by keeping off
the sampling noises completely outside area of the
audible band during conversion 24 to 16 bits.
CDR-W66 especially installs a high precision 24 bits
A/D Converter. This converter interlaces lower 8 bits,
the subsidiary part of the 24 bits signals, with the 16
bits format of the CDR.
SBM Filter is moreover featured with ON/OFF select
function; when OFF is s selected, the prescribed 8 bits
are definitely cut out.
Now that SBM is a technology to qualify the very
recording signals, any other CD players can realize the
high quality of the sound when playback is performed.

Depending on the headphones and your system, SBM
effects may not be wholly effective.
