R-4 Pro

Portable 4 Channel Recorder with Superior Sound Quality and SMPTE Time Code sync function

AES/EBU Input/Output 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 116 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 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.

Advantages of 4 channels recording.

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 for ambient sound.

Video editing environments now support multi-channel audio as standard.

AES/EBU Input/Output
The R-4 Pro is equipped with XLR style AES/EBU digital Input and Output for connection with pro Audio and Video recorders or sources.

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.

Superior 24-bit/192-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 to 192 kHz. Save data as BWF or WAV files.

Instant Backup via USB2.0 Instant Backup via USB2.0
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.

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 following hours.

Recording Time (Stereo)

	16bit	24bit
44.1kHz	116hours	77hours
48kHz	106hours	70hours
88.2kHz	58hours	38hours
96kHz	53hours	35hours
192kHz	26hours	17hours
* These recording times are approximate. Your actual results may vary somewhat. * If more than one recorded file exists, the recordable time will be less than these.

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 VCRs.
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.

DC Input for External Battery Power Supply 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 manufactures for video cameras such as Anton-Bauer, etc. Additional flexibility in power options include AA type battery power or AC power (via adapter).

Simultaneous 4-Channel Recording
The 4 XLR 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.

On-Board Limiter (selectable)
Built into the analog stage, the Limiter helps deliver a stable and reliable recording free of clipped noise from sudden input surges.

Limiter Operation

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.

Computer Linking Computer Linking
USB 2.0 provides a High Speed Computer Data Link. You can transfer the data about 20 times faster than DAT. You can also use R-4 Pro as a 80GB storage device. Edit R-4 Pro file directly from DAWs and other applications.

Wave Editing
Just watch the waveform on the LCD.
Scrubbing playback with the shuttle dial let you set the edit points precisely by sound.
