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 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
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.
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

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.
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, 88.2kHz, 96 kHz or 192kHz. Save data as WAV files.
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

Or you can record at several different level settings simultaneously.
The built-in Limiter helps deliver a stable and reliable recording
free of clipped noise from sudden input surges.
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.
The R-4 Pro lets you tailor the sound during both recording and
