DR-70D 4-Channel Audio Recording Device for DSLR and Video Cameras

Designed as an audio recording solution for filmmakers, the DR-70D 4-Channel Audio Recording Device for DSLR and Video Cameras from Tascam features dual built-in omnidirectional microphones and is capable of recording up to 4 tracks simultaneously. It has tripod mounts on both the top and bottom of the unit and can be mounted above or below your DSLR or video camera as well as on a follow-focus cage.
Recording to SD, SDHC, or SDXC cards up to 128GB, the DR-70D tracks in BWAV format for NLE compatibility. All integral parameters feature dedicated hardware controls, so you never have to go searching through menus to quickly change a setting. A dedicated camera output lets you send a mic-level signal to your camera's audio input to create a reference track for easier synching in post, while the dedicated headphone output allows you to monitor your audio.
