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 VTR's. 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
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
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 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
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
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
Use the jog dial to fast-forward or rewind at any of seven speed levels.
Built-In Stereo Speakers
The R-4 Pro's built-in speakers make it easy to monitor recorded sound
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 DAW's 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.
