Extended Recording with 40GB Hard Disk Drive
Equipped with a 40GB hard disk drive, the R-4 can record up to 17 hours
at maximum sound quality or up to 58 hours at CD quality.
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.
On-Board Limiter
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'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 lets you tailor the sound during both recording and playback.
L Terminal for Linking a Digital Video Camera
The R-4's L terminal lets you connect a similarly equipped digital
video camera to synchronize the camera start/stop while R-4 is recording.
Counting the camera's two channels, this configuration gives you a total of six
audio channels — a wealth of audio data to get creative with.
Waveform Editing Using Only the R-4
The R-4 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'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 as a 40GB storage device. Edit R-4 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.
CompactFlash™ Slot
The CompactFlash™ slot makes it easy to read or write recorded files.

to equipment not equipped with a USB interface.

with the coaxial digital audio in/out.
