The DR-701D is TASCAM's flagship recorder for single-shooter video production. A timecode generator is included for location reference, which can be jam synced from a SMPTE generator, camera, or smart slate. The HDMI in and out allows a DSLR camera to start recording on both devices, and video clock prevents drift between sound and picture. Four mic inputs can be individually recorded and mixed to a stereo track, for a total of six-track recording. For additional tracks, multiple units can be cascaded together. The lightweight yet rigid chassis is forged from a magnesium alloy. Tripod mounts on the top and bottom of the unit allow the unit to mount under a camera, attach to a follow-focus cage, or used stand-alone. Designed for the needs of professional filmmakers, television producers, advertisers, and documentarians, the DR-701D packs high quality multitrack recording into a package compact enough for use with any camera. Using the built-in mixer, 4 tracks and their stereo mix (6 tracks total) can be simultaneously recorded. In addition to pan and level adjustments, the mixer includes a delay function to compensate for distances between mics. A mid-side decoding function is also built-in for use with MS stereo mics. An HDMI input and output allows the DR-701D's internal clock and the camera to be digitally synchronized. Even when shooting long events, the video files recorded by the camera and audio files recorded by the DR-701D will not drift out of sync. Two omni condenser mics are built into the DR-701D for natural stereo sound images. Used in combination with small handheld or shotgun mics, speakers can be interviewed while capturing the surrounding environment in a compact setup. Many design features have been added to prevent damage, avoid blown takes, and improve usability. The HOLD switch makes it possible to disable unintended button presses during recording, and even includes the four gain adjustment knobs. The handles on the left and right sides protect the control surface and support attachment of a shoulder strap. In addition, the gain adjustment knobs are designed so they are not moved with a slight touch, making unintended moves less likely. Other details implemented for ease-of-use include an LCD screen and LEDs that promote high visibility even under direct sunlight.
