Detalii
The Edirol R-44 is a compact and light-weight 4-channel audio field recorder designed for professional use within a very conveniently sized package. Make professional quality recordings and capture up to 4 channels of uncompressed audio with selectable bit depths (16-bit or 24-bit) and sampling frequencies (44.1kHz/48kHz/88.2kHz/96kHz). The R-44 employs SD cards or large capacity SDHC cards as the recording media and no moving parts enables the most silent and reliable operation possible.
Specificatii tehnice
Built-in mics: Stereo microphones. Input sensitivity knob and high response meter enable precise level adjustment.
Phantom Power Switches: On/Off switch to control the phantom power supply to XLR input jacks. Independent control of each input.
Built-in speakers: Speakers for stand-alone monitoring.
Hold Switch: Prevents unintentional operations by locking the top and front panel buttons.
Low-Cut Switch: Rolls off low frequencies within input signals to prevent noise such as mic handling, breath pops or wind noise.
Limiter Switch: Suppresses sudden audio peaks and compresses signal to a threshold level. Independent On/Off or stereo link of channels 1-2 and 3-4 is possible.
Effects Button: Calls up on-board studio class effects. Assign to inputs and outputs as well as individual channels.
Scrub Dial: Enables speedy selection of parameters or changing values within menus. Moves current position forward or backward during playback or pause.
A-B Repeat Button: Set A-B points in a project to repeat playback between loop points.
Display: Organic LED provides high contrast and quick response with benefits of wide angle visibility.
Input Sensitivity & Level Knobs: Dual type knobs adjusts both input sensitivities and levels for Ch 1-4 independently.
Memory Card Slot: For SD and large capacity SDHC cards.
USB Port: Mini B type port for computer connection. Enables copying files to or from computers.
Control Sync: Link two R-44 units together for 8-channel recording.
Digital Output: Digital coaxial type connector for output to external digital devices such as speakers/mixers.
Digital Input: Digital coaxial type connector for inputting digital signals.
Line Output Terminals: Four RCA jacks for independent monitoring of all channels.
Combo Type Input Terminals: Support both balanced (XLR/TRS type) and unbalanced (standard type) inputs. Phantom power can be supplied to each XLR jack.
Built-In Effects:
3-Band EQ 3-band parametric EQ ; allows precise equalization with high/low shelving and peaking
6-Band Graphic EQ 6 point frequency band equalization; ideal for recording
Noise Gate Minimizes noise during low audio levels, cuts low frequency noise
Enhancer Cleary defines and enhances sound; good for dialogue
