Edirol R-4 PRO

The Edirol R-4 Pro shares the R-4's rugged construction, robust feature set and great sound quality, but the R-4 Pro also includes AES/EBU support, SMPTE time code and superb electronics. Record up to four channels at 24-bit 96KHz and monitor each channel discretely. The durable DC input jack allows for industry-standard battery packs to extend your record time. Its 80GB hard drive will store up to 125 hours of high quality audio. You can plug in any standard USB drive and enjoy fast back-ups of your projects. Like the R-4, the R-4 Pro has on-board effects and WAV editing features. Geared for pro videographers and recordists, the R-4 Pro delivers professional sound and features in a package that everyone can afford.
Why are 4-channels of audio better than 2-channels?
Capture more ambient sound at any shoot for an overall more convincing soundscape.
Place mics on each participant in conferences, panels, reporters, etc.
Redundancy or backup in case of camera mic noise or drop out.
Simplify wedding shoots with a mic on the bride, groom, officiator and a mic for ambient sound.
Video editing environments now support multi-channel audio as standard.

Features:

Master or Slave Sync with SMPTE Time Code
AES/EBU Input/Output
The R-4 Pro is equipped with XLR style AES/EBU digital Input and Output.
Instant Backup via USB 2.0
DC Input for External Battery Power Supply
The R-4 Pro is equipped with a 4-pin XLR type battery power input. This enables power supplies from industry standard battery manufacturers for video cameras such as Anton-Bauer, etc. Additional flexibility in power options include AA type battery power or AC power (via adapter).
Individual Monitoring of 4 channels
Extended Recording with 80GB Hard Disk Drive
Equipped with a 80GB hard disk drive, the R-4 Pro can record a stereo audio file for approximately116 hours at 16bit/44.1kHz/ 106 hours at 16bit/48kHz, 70 hours at 24bit/48kHz, 34 hours at 16bit/96kHz, and 30 hours at 24bit/96kHz.
Superior 24-bit/96-kHz Linear Recording
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: The built-in Limiter helps deliver a stable and reliable recording free of clipped noise from sudden input surges.
Built-In Nondirectional Stereo Microphones
The R-4 Pro'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 Pro lets you tailor the sound during both recording and playback
Waveform Editing Using Only the R-4 Pro
The R-4 Pro 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
Easy Playback with the Jog Dial
Built-In Stereo Speakers
USB 2.0 Terminal Provides a High-Speed Computer Data Link
Advanced Linking with the EDIROL DV-7DL
