An on-board limiter helps suppress sudden peaks in sound from an input source. A low-cut filter is included to help prevent things like wind noise or mic handling noise. Studio class effects such as 3-Band EQ, 6-Band GEQ, Enhancer or DeEsser can be used as tools to greatly improve audio quality. Effects can be applied while recording or simply for monitoring/playback.

The Pre-Record function buffers input signals for a user-definable amount of time. When the REC button is pressed, the material from the previous few seconds (selectable) is included. This also helps reduce sound bites at the beginning of a recording by not having to start the recorder too early.

The combo input jacks (4) supports the connection of both XLR and 1/4 inch plugs. XLR inputs are equipped with phantom power. Eleven steps of input sensitivity enable the connection of various devices with a variety of inputs levels from microphones to musical instruments. High quality analog circuitry in the preamp ensures superior recording results.

The high contrast, high response organic LED screen, viewable from wide angles ensures fluid operation in field recording situations. The high response of level meters makes precise level adjustments possible. All the necessary switches and knobs are located on the top and front panels. Self-lit buttons on all the key controls enable clear-cut recording operations.

The Control Sync terminal enables synchronized operation of 2 units. Control the second unit from the master by simply connecting two with a stereo mini cable. The master unit can remotely control REC standby, REC start and REC stop of the slave unit. This function enables 8-channel recording in a compact space and at an affordable price.

The Edirol R44 Portable Recorder storage can be mounted on computers with a simple USB 2.0 connection. It is seen as an USB storage device on any computer. You can copy data back and forth with a simple drag & drop operation.

The Edirol R44 Portable Recorder can be operated with 3 types of power: AC adaptor, 4-pin external battery and AA batteries. Four hours of operation is possible with NiMH or alkaline batteries, at 16-bit/44.1kHz stereo.  On batteries, there is no phantom power and pre-record is disabled.
