Tascam DR-70D 4-channel audio recorder for DSLR cameras

The DR-70D is a compact audio recorder that allows the aspiring DSLR user to create audio recordings in very high quality in parallel to their film or video shots. The recorder can be mounted directly between a tripod and the camera or on top of the camera, resulting in a compact package.

With its two built-in microphones, the DR-70D is instantly ready for use in standard situations. In addition, it provides four XLR/TRS combo jacks which can be used to record four channels of audio with excellent sound quality using professional microphones. Thanks to a camera output the recorder’s stereo signal can be recorded also on the camera to ease subsequent editing of the material in combination with the slate tone function of the recorder. On the other hand you can use the camera input to monitor the audio of the camera using the recorder.

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.

• Built-in mixer with 4 inputs and 2 Outputs
• High audio quality through HDDA microphone preamps
• Compact and tough design
