Portable recording, 40GB hard disk drive for extended recording, record up to four channels at once and edit waveforms on the recorder itself, compact size and light weight.
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.
Totally uncompressed recording assures 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.
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.
Built into the analogue stage, the Limiter helps deliver a stable and reliable recording free of clipped noise from sudden input surges.
The R-4's omnidirectional microphones offergood 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.
Five High-Quality Effects
3-Band EQ: 3-band parametric EQ; allows sharp equalizing with high/low shelving and mid peaking
Graphic EQ: 6-point frequency band equalizing
Noise Gate: Minimizes noise during silences, cuts low-frequency noise
Enhancer: Clearly defines and enhances sounds good for dialogue
Comp & DeEsser: Cuts hissing, smoothes the sound, makes the sound level uniform
Only one effect can be used at a time. Effect ON/OFF and parameters can be set for each track.
Effects are not available in 96-kHz operation.
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
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 aComputer 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.
The CompactFlash slot makes it easy to read or write recorded files. You can use CompactFlash 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.
Digital Audio Input/Output
Exchange data with other digital equipment while maintaining fidelity with the coaxial digital audio in/out.
Soft Carrying Case
The R-4 comes with a soft carrying case with a shoulder strap for safe, use in the field.
