M2 overview
Realizing high audio quality throughout recording and
editing
With dual A/D converter circuits and support for 32-bit float WAV files, the M2 can maintain the highest
audio quality from recording to post-production.
Recording
Dual AD converter circuits enable recording from quiet to loud volumes without any need to make gain
adjustments.
Post-production
Recording with 32-bit float WAV file format allows the recording audio quality to be retained when editing.
5
Dual A/D converter circuit overview
For each input circuit, the M2 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.

provides the best recording results.

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 during post-
production.
Resolution advantage
32-bit float WAV files have the advantage of being able to maintain high resolution even at low volumes. As
a result, quiet sounds can be made louder when editing after recording without degrading their quality.
■ 16/24-bit WAV

Resolution low
■ 32-bit float WAV

Clipping advantage
If a waveform sounds clipped when output from the M2 or in a DAW, it can be edited after recording to
lower its volume and restore an unclipped waveform because the data in the 32-bit float WAV file itself is
not clipped.
■ 16/24-bit WAV
