  • Page 5: F3 Overview

    F3 overview Achieving high audio quality throughout recording and editing With dual AD converter circuits and support for 32-bit float WAV files, the F3 can maintain the highest audio quality from recording to post-production. Recording Dual AD converter circuits enable recording the loudest to the quietest sounds without adjusting gain.
  • Page 6 Recording with 32-bit float WAV file formats allows the same audio quality to be retained when editing. Dual AD converter circuit overview For each input circuit, the F3 has two AD converters with different input gains. This design enables high- quality audio recording without the need to adjust gain settings, a step that is normally indispensable.
  • Page 7 Switching between two AD converters The F3 constantly monitors data from the two AD 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...
  • Page 8 Clipping advantage If a waveform sounds clipped when output from the F3 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.
