DSP (Digital Signal
Processing) Settings
You can make recordings of analog input signals while
applying the following processes: Digital equalizer,
digital limiter, and Super Bit Mapping. The block
diagram of the analog input signal part to the CD
recorder is shown below.
Using SBM (Super Bit Mapping)
To make recordings using the SBM filter, set the SBM/
LIMITER/EQ control to “SBM” or “SBM + LIMITER +
EQ”.
SBM Filter
The CD recorder is equipped with a 24-bit A/D
converter, but the CD format itself is set at 16 bits as the
universal standard. Consequently, you must convert
the data, which was A/D-converted using 24 bits, to 16
bits to record. In this case, the simplest method is to
omit the least-significant 8 bits of the 24-bit data. (This
happens when SBM is turned OFF.) This, however,
wastes much of the 24-bit data output from the A/D
conversion. Using SBM processing, the least-significant
8 bits of the 24-bit data is woven into the 16-bit data
while pushing outside of audible range the quantum
noise when converting to 16 bits, by creating in the
noise shaping filter frequency characteristics that take
account of human auditory characteristics. In this way,
although called 16-bit data, you can record the detailed
sound quality on the original 24-bit data without
degradation. In addition, SBM function operates
during recording, so discs recorded using SBM
processing reproduce the same sound quality when
played on other CD players.

Depending on the headphones and your system, SBM
effects may not be wholly effective.
Fade-in/Fade-out
Recording
Fading In Recordings
1 Make sure that the CD recorder is in recording
standby mode.
2 Press the FADER button.
Recording will begin once the last sound has
gone, and the volume will rise automatically to
the normal recording volume.
Fading Out Recordings
1 Make sure that the CD recorder is in recording
mode.
2 Press the FADER button.
The volume will automatically decrease and the
CD recorder will enter record standby mode.

Adjusting Fade-in/Fadeout Time
You can set the fade-in/fadeout time between 1 and
8 seconds, using “Fader Time” in the Setup menu
screen.
