The R-44 portable field recorder from Edirol/Roland is an ideal choice for videographers, musicians, sound designers, and more. The ultra-portable unit weighs under three pounds but packs a number of great features. Record up to four channels of linear PCM audio at a variety of bit rates and sampling frequencies; up to 24-bit/192kHz! The recorder offers four XLR/TRS combo jack inputs for great versatility. The XLR connections have phantom power, allowing you to use your favorite condenser mic. The R-44 can record to widely-available SD or SDHC flash memory cards, making it easy to store and share your audio. Because there are no moving parts, the R-44 delivers silent, reliable operation that you can depend on. In addition to the input connectors, the R-44 also offers built-in stereo microphones and monitor speakers, allowing you to record and play back audio without any additional equipment. What's more, is that the unit will operate for up to four hours on four AA batteries. You can also use the AC adaptor, or a four-pin external battery for powering the device. Built-in effects include a three-band parametric EQ and a six-band graphic EQ, a noise gate, compressor, de-esser, limiter, and low-cut filter. A pre-record function keeps the R-44 listening at all times, so that when the record button is pressed, the previous few seconds of audio (selectable) are captured to your memory card. The R-44 has an easy-to-use interface, complete with a high-contrast OLED display, perfect for viewing under any conditions. You can also capture up to eight channels of audio by linking two R-44 units together. A high-speed USB 2.0 port lets you transfer your audio files quickly to a Mac or PC.
