The compact format can be mounted either above or below a camera, and a pair of built-in microphones can capture sound on-set. The interface is designed for quick adjustment, with additional features to keep recording levels under control.  

Four XLR mic inputs with phantom power are included on the DR-70D, enough to cover busy scenes. The High-Quality HDDA(High Definition Discrete Architecture) Mic Preamps  include 64dB of gain for quiet performances, and all four inputs have individual gain controls. Each input has a limiter and low cut filter available for controlling volume. Also included is Dual Recording mode, which records a safety copy of your audio at a lower level to prevent distorted takes. Quality components like 5532 op amps are used throughout for the clearest audio possible.

Tracks on the DR-70D are captured to SD card, SDHC or SDXC media – up to 128GB cards are supported. The recorder has tripod mounts on the top and bottom of the unit, allowing it to be mounted on a camera, a follow-focus cage, or used standalone. Other production friendly features include a slate tone, low-noise buttons, a powerful headphone output, and standard AA battery power.

Uniquely designed for the needs of filmmakers, television producers, advertisers, and documentarians, the DR-70D packs multitrack recording into a package compact enough to use with any camera.
