Advanced Recording
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.
Built-In
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 nondirectional, 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/actualitie at the beginning
of a recording.
Five High-Quality Effects
The R-4 lets you tailor the sound during both
recording and playback.
*Built-In Effects
Wave Editing
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.
*Waveform Editing Functions
| Trim (Delete) | Select two points and remove the waveform between them |
| Divide (Split) | Select one point and divide the file there |
| Divide (Split) | Combine a file with the one before it |
| Merge (Bounce) | Merge several channels into one |
Easy Playback
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.
Computer Linking
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
Advanced Linking with the EDIROL DV-7DL Editor
and exchange files.
CompactFlashェ Slot
The CompactFlash slot makes it easy to read
or write recorded files. You can use CompactFlashェ
memory to give data to colleagues or to transfer
data to equipment not equipped with a USB
interface.
2-Way Power Supply
The R-4 runs on eight AA batteries
or with the AC adaptor.
