SBM (Super Bit Mapping)
Function
During analog recording, the SBM function lowers
noise within the frequency band to which to the human
ear is most receptive to noise, thereby, sharply
expanding the auditory dynamic range of the recorded
signal.
High-precision pulse A/D converter
The deck uses a pulse AD converter and decimation
filter to convert an analog signal into a quantized 24-bit
digital signal. The deck, like CD players, uses 16-bit
quantization, and thus the 8-bit difference results in
more precise quantization, more signal information
and less quantizing noise than 16-bit quantization.
During conversion of the 24-bit data to a 16-bit
recording signal, the SBM function boosts sound
quality by reintegrating 4 bits of signal information
that would normally be lost into the 16-bit signal.
