Product Description

For versatile audio production, the DR-70D features four XLR Inputs and a stereo microphone. The DR-70D from TASCAM is the ultimate audio recording solution for filmmakers. Four balanced XLR mic inputs meet the requirements of production sound, from professional users to indie DSLR shooters. 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.

Two built-in omni-directional mics
Two omni-directional microphones allow easy recording of natural stereo sound without using external mics. Used in combination with one or two other mics, the DR-70D becomes a compact setup for recording interviews and ambient sound at the same time.

4 XLR/TRS combo jacks allow a variety of setups
(4) XLR/TRS inputs are built-into the DR-70D. The four-channel design enables combinations of shotgun microphones, lavaliere mics, and the built-in stereo mic to be recorded individually. Channels 1 and 2 can be set to stereo input and channels 3 and 4 can be set to the built-in mics, making a variety of mic configurations possible.

Dual Recording mode can be used to create a backup file that is simultaneously recorded at a different level to prevent clipping when levels exceed the maximum input. The second track is recorded up to 12dB lower as a safety track to prevent distortion – if your input signal overloads, you have a backup that isn't distorted.

Built-in 4-in/2-out Mixer Enables 4-channel and Stereo Recording
Each of the four inputs is sent to a stereo mixer. This allows each input to be recorded individually for post production while a stereo mix is sent to headphones and the camera guide track. In addition to pan and level parameters, each input includes a limiter, a low-cut filter, and a delay to adjust for distances between mics. In addition, a mid-side decoding function enables the use of a MS stereo mics.

HDDA (High Definition Discrete Architecture) mic preamps
Microphone preamps do a lot of work to convert your mic-level signals to recordable levels, so they have a big impact on the quality of the audio that is recorded. The DR-70D uses TASCAM HDDA microphone preamps - created through careful selection of parts. An NE5532 op-amp was selected for its outstanding effect on audio quality. Through a mix of discrete architecture and hand-picked components, TASCAM has achieved an equivalent input noise level of -120 dBu.

A great little field recorder that packs a punch.

Product Review

This little guy may be small but it gives you a ton of control over your recordings. It's small profile keeps it out of the way, but is right there when needed.

Tascam does it again!

Product Review

I do a lot of field recording of sound effects and remote recording of concerts and such, and I just bought this as an upgrade to my DR40. All I can say is this thing is amazing! It is only a tiny bit bigger than the DR40, and designed to either mount to a camera or hang from your shoulder with a strap. It is lightweight, and the preamps (the most important thing) are clean, quiet, and wonderful. The battery life seems to be poorer than the DR40 however, I am also recording 24/96k, and I never did that with the DR40. Perhaps that is draining the battery faster. If you do any sort of remote field recording, this thing can not be beat for the price. My favorite aspect of the Tascam line is the "dual record" function, allowing you to record a safety copy at a lower volume in case of unanticipated clipping on the main track.
