M4 overview Realizing high audio quality throughout recording and editing With dual A/D converter circuits and support for 32-bit float WAV files, the M4 enables the highest audio quality to be maintained from recording to editing in a DAW or other software. Recording Dual AD converter circuits enable recording from quiet to loud volumes without any need to make gain adjustments.
Page 6
Dual A/D converter circuit overview For each input circuit, the M4 has two A/D converters with different input gains. This design enables high-quality audio recording without the need to adjust gain settings, a step that normally had been indispensable. Providing amazing dynamic range By combining two A/D converters, a wide dynamic range not possible with a single A/D converter has been realized.
Page 7
Switching between two A/D converters The M4 constantly monitors data from the two A/D converters and automatically selects the one that provides the best recording results. Low noise No clipping Low noise because high-gain because low-gain because high-gain AD converter selected AD converter selected AD converter selected...

32-bit float WAV file overview 32-bit float WAV files have the following advantages over conventional 16/24-bit WAV files. These features enable the quality of the sound during recording to be maintained even when editing with DAW software afterward. Resolution advantage 32-bit float WAV files have the advantage of being able to maintain high resolution even at low volumes.
