  • Page 6: R4 Overview

    R4 overview The R4 is a compact 4-track MTR designed for musicians that enables musical ideas to be captured anytime anywhere. The bounce function enables repeat recording to capture more than 4 tracks using the 2 XLR/TS combo inputs, the built-in mic and the onboard effects. 32-bit float technology frees you from monitoring levels when recording and allows you to focus on the creative aspects of music production.
  • Page 7 Switching between two A/D converters The R4 constantly monitors data from the two A/D converters, and automatically selects the one that provides the best recording results.
  • Page 8 32-bit float WAV file overview 32-bit float WAV files have the following advantages over conventional 16/24-bit WAV files. Thanks to these advantages, the sound quality during recording can be retained when editing afterward using a DAW or other software. Resolution advantage 32-bit float WAV files have the advantage of being able to maintain high resolution even with quiet sounds.
  • Page 9 ■ 32-bit float WAV Resolution is high Volume raised Clipping advantage If a waveform sounds clipped when output from the R4 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.
