The R-4 is uniquely designed to offer sound professionals a cost-effective, high-quality solution to multi-channel field recording. The ability to record 4-channels in 24-bit/96kHz resolution and edit the file in the R-4 (which could contain anything from an interview to a concert), for immediate broadcast right out of the R-4 is of inestimable value to an audio or broadcast professional on a tight schedule. All this plus a compact size and light weight that assure outstanding mobility in the field. The Edirol R-4. Gear up for the new generation of portable recording.
Extended Recording with 40GB Hard Disk Drive
The R-4 records directly to an internal 40GB hard drive providing storage capacity for 58 hours of CD quality 16-bit/44.1kHz stereo recording or over 17 hours at 24-bit/96kHz. The R-4 can record at audio resolutions up to 24-bit/96kHz on all four channels, for total high-resolution multi-channel performance. The unit features a built-in limiter and 5 different dynamic processors; 3-Band Parametric EQ, 6-Band Graphic EQ, Noise Gate, Enhancer, and Compressor / Desser. more
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.
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. The built-in wave editing is designed to offer the user immediate access after recording to make quick edits before getting into the studio. This would be for situations where you either won’t have access to editing later, or just want to do it while you remember what you need to edit. It is perfect for sound designers or those who need to be able to quickly
get a good representative product to their editor/news team, etc.
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.
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. In addition, the R-4 also provides 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.
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.
USB 2.0 Terminal Provides a High-Speed Computer Data Link
The USB 2.0 high-speed mode transfers data about 20 times faster than DAT. You can also use the R-4 as a 40GB storage device. Edit R-4 files directly from DAWs and other applications. EDIROL designs its USB devices in accordance with USB specifications and has passed all compatibility tests, which are continuously held and organized by USB Implementers Forum (USB-IF).
