Roland R44 4-channel Recorder
The R-44 is a compact, four channel, solid-state field recorder that uses SD or large capacity SDHC cards as the storage media enabling quiet and reliable recording for a variety of professional audio needs. 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/192kHz). Onboard effects include limiter, low cut filter, 3-band EQ, 6-band GEQ, Enhancer, and DeEsser. The R-44 is a part of our series of audio field recorders.
