The 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.
Master or Slave Sync with SMPTE Time Code
The R-4 Pro accepts SMPTE time code which enables it to slave to video cameras or VTRs. Four channels of high quality audio can be fully synchronized with video. In addition, the R-4 Pro can also act as the master, sending out time code to slave devices.
The R-4 Pro is equipped with XLR style AES/EBU digital Input and Output.
Instant Backup via USB 2.0
The USB host terminal of R-4 Pro enables high speed and instant backup of recorded data to affordable and easy obtainable media like Flash Memory, Memory Cards via card reader or HDD storage. Easy and high speed duplication of recorded data improves production workflow across multiple locations.
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
Individual monitoring of all channels is enabled via the four analog outputs. This allows precise monitoring of all recorded audio.
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
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.
Built-In Nondirectional Stereo Microphones
The R-4 Pro’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.
Five High-Quality Effects
The R-4 Pro lets you tailor the sound during both recording and playback.
Built-In Stereo Speakers
The R-4 Pro’s built-in speakers make it easy to monitor recorded sound without headphones.
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 Pro as a 80GB storage device. Edit R-4 Pro files directly from DAWs and other applications.
Advanced Linking with the EDIROL DV-7DL
A USB cable is all you need to connect directly to an EDIROL DV-7DL Video Editor and exchange files.
Soft Carrying Case
The R-4 Pro comes with a soft carrying case with a shoulder strap for safe, comfortable use in the field.
