DR-70D
4-TRACK AUDIO FIELD RECORDER & MIXER FOR AUDIO/VIDEO
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.

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.
MONO/DUAL MONO：Best for recording the audio of a single performer.
STEREO/DUAL STEREO：Best for recording with the built-in microphones or a stereo mic.
2MIX/DUAL 2MIX：Creates stereo files of two or more mixed inputs.
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.
Two built-in Omnidirectional Microphones
Two omnidirectional 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.
Built-in 4-in/2-out Mixer Enables 4-channel and Stereo Recording
Each fo 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 being able to adjust pan parameter, 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.
The A/D converter is made by CIRRUS LOGIC, similar to those used in the TASCAM DR series of linear PCM recorders. This high-quality converter – miles better than those included in DSLR cameras – ensures quiet, clean audio recording. Audio resolutions up to 96kHz/24-bit are supported.
