Superior 24-bit/96-kHz Linear Recording

Totally uncompressed recording assures outstanding sound quality. Choose 16-bit or 24-bit quantization and a sampling rate of 44.1 kHz, 48 kHz, or 96 kHz. Save data as WAV files.

Simultaneous 4-Channel Recording

The 4 XLR/Phone combo jacks come with switchable phantom power and give you a choice of MONO, STEREO, STEREO X2, or 4CH recording. Digital input/output is also provided.
Four-channel recording gives you exceptional flexibility. For example, you can use mics to capture the ambience of a performance hall while using line input to record the performance itself. Or you can record at several different level settings simultaneously.

On-Board Limiter

>Built into the analog stage, the Limiter helps deliver a stable and reliable recording free of clipped noise from sudden input surges.

Built-In Nondirectional Stereo Microphones

The R-4’s omnidirectional, back electret condenser microphones offer superb transient characteristics and vibration resistance.

Pre-Recording Function

When the REC button is pressed, the current material is appended to a buffer that contains recorded material from a few seconds earlier. This helps prevent missed recording opportunities or sound bites at the beginning of a recording.

Five High-Quality Effects

The R-4 lets you tailor the sound during both recording and playback.

L Terminal for Linking a Digital Video Camera

The R-4’s L terminal lets you connect a similarly equipped digital video camera to synchronize the camera start/stop while R-4 is recording. Counting the camera’s two channels, this configuration gives you a total of six audio channels ? a wealth of audio data to get creative with.

Waveform Editing Using Only the R-4

The R-4 is all you need to edit waveforms. Just watch the waveform on the LCD as you edit. Scrubbing playback with the shuttle dial lets you set the edit points precisely by sound.

Index Any Point Instantly

Press the mark button anytime during recording or playback to mark that point for easy, instant indexing later. With the A-B repeat function you can set two points and repeatedly play back the material between them.

Easy Playback with the Jog Dial

Built-In Stereo Speakers

The R-4’s built-in speakers make it easy to monitor recorded sound without headphones.
