Sale DR-70D 4-Channel Audio Recording Device for DSLR and Video Cameras Digital Audio Recorders|Audio Recording Devices

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. (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.

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 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. 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.

The DR-70Ds design is as compact as possible to stay out of the way while filming. The bottom of the unit has tripod screw threads for mounting under your camera or on a follow-focus cage. A removable camera attachment screw and hot shoe for the top of the unit are also included. The DR-70D can be attached in the way most convenient for the user by placing it between a tripod and the camera, or on top of the camera with a hot shoe mount. The built-in generator can produce slate tones that can be used as references when aligning audio and video. Line up the waveforms when you need perfect sync between 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. The 3.5mm stereo 1-2 input mini jack allows the connection of consumer video camera mics. For example, connect a video camera mic for ambiance to jack 1-2, and shotgun mics to the XLR 3-4 jacks. This unit can supply plug-in power to the microphone and has a maximum input level of +10 dBV. The Camera In jack allows playback from your camera to evaluate a take. Either the camera signal or DR-70D can be monitored through the headphones.
