A compact, solid state,
four channel field recorder.

The Edirol R-44 is designed for professional use
within a very conveniently sized package. 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). R-44 employs SD
cards or large capacity SDHC
cards as the recording media.
No moving parts enables the
most silent and reliable
operation possible.

Although the R-44 is compact, all the necessary
functions are included. Built-in high quality
microphones and speakers make recording and
monitoring without external devices possible.

An on-board limiter helps suppress sudden peaks in
sound from an input source. Alow-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
certain 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
