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.
