Tascam DR-70D - 6 input and 4 track multitrack field recorder
Compact professional audio recorder for use with DSLR camera. Uses SD/SDHC/SDXC cards for storage (up to 128 GB). Capture up to four tracks of high-resolution audio from external sources and built-in omnidirectional microphones, route audio to and from your camera, and monitor conveniently through headphones.
For film, television and webcasting applications where you want to record live and ambient sound, the Tascam DR-70D multitrack field recorder is the ideal companion for your DSLR. Capture up to four tracks of high-resolution audio from external sources and built-in omnidirectional microphones, route audio to and from your camera, and monitor comfortably through headphones. With strap handles, a tripod mounting socket and camera screw attachment, the DR-70D is compatible with a variety of setups and working styles.
Its four balanced XLR-1/4" combo inputs support mic- or line-level signals (including +4 dBu from high-end sound mixers). With individually switchable phantom power (24 or 48 V) and up to 63 dB gain, the low-noise HDDA (High Definition Discrete Architecture) microphone preamplifiers can be used for a wide variety of microphones, such as dynamic, ribbon or condenser microphones. A 3.5 mm mic/line input with selectable plug-in power is provided for situations that require recording a lavalier microphone or output from a wireless receiver. In addition, two 3.5 mm outputs are provided for simultaneous connection of camera and headphones.
The DR-70D's two built-in condenser microphones allow stereo sound to be captured without the need for external microphones. The omnidirectional microphones respond to sound from all directions and are permanently separated in an A/B configuration, producing a wide, spherical pickup pattern.
To maximize compactness and portability, the DR-70D records directly to media cards (available separately). It is compatible with SD, SDHC and SDXC cards (with a capacity of up to 128 GB). In addition, it is ideal for tripod or camera use as it can be placed between a DSLR camera and a tripod or mounted on a cage or follow-focus equipment. Handles on the front left and right sides protect the screen and allow attachment of a shoulder belt.
Each input features adjustable pan, level, limiting, polarity and up to 150 ms delay. Mitigate wind noise and low-frequency rumble by selecting the low-cut filter, which can be set at 40, 80, 120, 180 or 220 Hz. It also features a tone generator for file synchronization.
This recorder supports external remote control via the RC-3F footswitch or RC-10 wired remote control (both available separately); start/stop recording, make marks, increment tracks and more without having to touch the DR-70D.
