Applying dithering to recording
When recording in 16-bit WAV format the dynamic range is
about 96.3 dB.
You can set how the unit processes the quiet sounds above the
16-bit range that are lost (quantization noise) when it records.
1. Select DITHER on the REC 4 page to open the DITHER
screen.(see “Menu operation procedures” on page 22)
2. Set the dither mode.
Option Meaning
OFF (default)
No dithering is conducted. Unusable quanti-
zation bits (17 and higher) are cut, while the
16th bit and below are recorded as is.
DITHER
Random noise (white noise) that is half the
size of the smallest quantization bit (16th
bit) is added, generating fluctuation in the
border between the 16th and 17th bits and
suppressing quantization noise.
NOISE SHAPE
This is linear noise shaping. Quantization
noise itself is fed back and differentiated to
suppress the noise and expand the dynamic
range.
3. Confirm the setting and return to the Menu Screen.
Using the sampling rate converter
This unit has a built-in sampling rate converter, so it is possible
to record with a sampling frequency that is different from the
digital input sources.
When the sampling rate converter is on, the icon appears in
the recording function activation status area on the recording
screen.
1. Select SRC on the REC 4 page to open the SRC screen.(see
“Menu operation procedures” on page 22)
2. Turn the sampling rate converter (SRC) on or off.
Options: OFF (default), ON
3. Confirm the setting and return to the Menu Screen.
NOTE
i If you try to record a digital signal through a digital input con-
nector with the sampling frequency that is different from the
one set on the SAMPLING RATE screen when the sampling rate
converter (SRC) is off, a “-- DIN ERROR -- Digital input
is illegal.” message will appear.(see “Setting the record-
ing file format” on page 57)
i The sampling rate converter operation range is 32–192 kHz.
Setting the pause mode
You can set the unit to either increment the track number (create
a new file) or not when you switch it from recording to recording
standby (pausing).
1. Select PAUSE MODE on the REC 4 page to open the PAUSE
MODE screen.(see “Menu operation procedures” on page
22)
2. Set the pause mode.
Option Meaning
SAME TRACK
(default)
Track number not incremented when switch-
ing from recording to recording standby.
NEW TRACK Track number incremented when switching
from recording to recording standby.
3. Confirm the setting and return to the Menu Screen.
CAUTION
This cannot be changed when recording or in recording
standby.
Skipping recording standby before
recording (direct recording)
Recording can be started without entering recording standby
first.
When this function is on, pressing the RECORD button will start
recording immediately.
1. Select DIRECT REC on the REC 4 page to open the DIRECT
REC screen.(see “Menu operation procedures” on page 22)
2. Turn the direct recording function on or off.
Options: OFF (default), ON
3. Confirm the setting and return to the Menu Screen.
