Many DSLRs can now capture HD video, many also have microphone inputs. However most do not have headphone monitoring or metering capabilities, and none have on-board mixers.
The DC-R302 is a professional stereo recorder with on-board 3-ch pre-amp audio microphone / line mixer designed for use with video-capable DSLRs. Recording pristine quality stereo audio direct to SD cards, the DC-R302 not only allows DSLRs to be easily used in field production applications, it also simplifies the capturing process allowing the camera operator to operate the recorder and camera at the same time.
Housed in a rugged, extruded aluminium chassis the DC-R302 combines Fostex's usual high pedigree of electrical engineering and mechanical construction with a compact footprint and high-quality components. Main features of this no-compromise unit include up to 24bit / 96kHz stereo recording to SDHC cards, 3 channel mic/line mixer with XLR inputs, 48V Phantom Power, limiters and high pass filters, slate tone, flexible on-board headphone monitoring, remote DSLR control and large LCD metering.
