SBM(Super Bit
Mapping)
When LPCM 16bit REC Mode is selected, you can reduce noise using
the Super Bit Mapping function.
ON: The Super Bit Mapping function works to reduce noise.
OFF*: The Super Bit Mapping function is disabled.
Note
 Super Bit Mapping significantly increases the dynamic range
acoustically by reducing noise that is particularly easy to hear within the
band audible to humans. In order to improve the audio quality when
converting 20-bit data into 16 bits, the top 4 bits of information within
the lower data, which is usually discarded, is integrated into the 16-bit
data.
Peak Hold You can select whether the maximum value of the input signals
(peak value) is maintained.
Auto*: The peak value is not maintained and is reset periodically.
Manual: The peak value is maintained and displayed until you stop
recording or execute “Reset Peak Data.”
