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.

Features of the DR-70D include overload-resistant, great-sounding preamps with switchable low-cut filter and limiter, handling of microphone signals in mid/side format, 24- or 48-volts phantom power for condenser mics, as well as many common and not so common functions that facilitate capturing, monitoring and subsequent processing of the audio tracks.

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 microphones

The two omnidirectional microphones allow you to easily record natural stereo sound with just this unit. Used together with small shotgun mics, you can even record audio from people speaking in an interview and the ambient sound at the same time (on different tracks), for example, with a compact set up.

4 XLR/TRS combo jacks allow a wide range of setups

The four-channel design enables use of two shotgun mics and the stereo mic to record ambiance and each speaker individually. Since channels 1 and 2 can be set to the stereo input and channels 3 and 4 can be set to the built-in mic, a large variety of microphone setups is possible.

• MONO/DUAL MONO mode: This is best for recording the audio of a single performer.
• STEREO/DUAL STEREO mode: This is best for recording with the built-in microphone or a stereo mic.
• 2MIX/DUAL 2MIX mode: This creates stereo files of the signals of multiple inputs that have been mixed.

Built-in mixer with 4 inputs and 2 outputs

The mixer can take a total of 4 channels from among the four XLR inputs that support phantom power, the stereo mini-jack input and the built-in stereo mic. In addition to adjust pan and input level, this unit also offers a limiter, a five-setting low-cut filter and a delay that can compensate for distances between mics. Moreover, a mid-side decoding function allows the use of two microphones in mid-side configuration.

High audio quality through HDDA microphone preamps

Mic preamps, which receive and amplify microphone input signals, have a large impact on the quality of the recorded audio material. The DR-70D uses Tascam original HDDA (High Definition Discrete Architecture) microphone preamps that we created through careful selection of parts. For example, we chose the NE5532 for the operational amplifier, which has a strong effect on audio quality. With a mic amp circuit that uses discrete architecture comprised of meticulously-chosen parts, we have achieved an equivalent input noise of −120 dBu.

The A/D converter that converts analogue signals to digital is made by Cirrus Logic and is equivalent to those used in our successful DR series of linear PCM recorders. Recording at resolutions up to 96 kHz/24 bit is supported.

Compact and tough design

The designer of the DR-70D focused on making the unit small so that it does not interfere with camera-work when it is attached to a camera support system or stabilizer. The unit has tripod screw threads on the bottom side and a removable camera attachment screw on its top. A hot shoe mount is also included so you can attach the recorder in the way most convenient for you by placing it between a tripod and the camera or on top of the camera with a hot shoe.

• Stand adapter (¼ inch) on bottom side to attach the unit to a tripod
• DSLR bracket for easy camera attachment and removal
• Hot shoe mount (accessible when not using the DSLR bracket)
• Handles on the front left and right sides protect the screen and can be used to attach a shoulder belt

Camera input and output

The DR-70D has a camera input jack that can be used to monitor the audio from the camera. By using this with the DR-70D monitor selection function, you can efficiently monitor the audio from not only the DR-70D but also from the camera.

The camera output jack is designed to output the mixed audio to the camera so that the same audio can be recorded by the DR-70D and the camera. Since the input level varies by camera maker and there are usually, few adjustments related to volume on cameras, this unit has an output volume dial that can be used to make adjustments.

Slate tone generator for easy alignment with video files

The built-in generator can produce slate tones that can be used as references when aligning audio and video. In addition to being able to produce slate tones when recording starts or when it starts and stops, the SLATE button can be used to add slate tones at any desired point.

• Automatic insertion: Choose from inserting a slate tone at the beginning of recording or at both the beginning and end of recording
• Manual insertion: Press the SLATE button to produce a tone.
