Main Features
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
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.
AES/EBU
Input/Output
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
24bit/96kHz.
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, 88.2kHz, 96 kHz or
192kHz. 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 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.
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 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 Pro as a 80GB
storage device. Edit R-4 Pro
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.
Soft Carrying
Case
The R-4 Pro comes
with a soft carrying case
with a shoulder strap for
safe, comfortable use in the
field.
