For filmmaking, television, and web broadcast applications where you want to record direct sound and ambience, the Tascam DR-70D multi-track field recorder is an ideal companion for your DSLR. Capture up to four tracks of high-resolution audio from external sources and the onboard omnidirectional microphones, route audio to and from your camera, and conveniently monitor through headphones. With strap-friendly handles, a tripod mounting socket, and a camera-mount screw attachment, the DR-70D is compatible with a variety of setups and working styles.

Versatile powering methods and remote-control options make the DR-70D ideal for location recording and extended video shoots. Its four balanced XLR-1/4" combo inputs handle mic- or line-level signals (even +4 dBu from high-end sound mixers) and can independently supply phantom power. A 3.5mm mic/line input with selectable plug-in power is provided for situations that require you to record a lavalier microphone or the output of a wireless receiver. Utilize settings such as stereo safety track recording, limiting, and low-cut filtering to achieve a clean, undistorted recording.
