DR-701D

Six-channel recording (four channels + L-R stereo mix)

Using the built-in mixer with four inputs and two outputs, four audio channels and their L-R stereo mix (six channels total) can be recorded simultaneously. In addition to pan and level adjustments, the mixer also includes a delay function that can compensate for distances between mics. A mid-side decoding function is also built in for use with mid-side stereo microphone setups.

High audio quality through HDDA microphone preamps

The mic preamps that amplify the audio output from microphones have a significant impact on the quality of the recorded audio. The DR-701D features TASCAM HDDA mic preamps. The differential mic preamp circuits use discrete architecture and are made with carefully selected components. For example, op amps have a great impact on audio quality, so the OPA1652 by Texas Instruments was selected, which has even higher quality and lower noise than those used in the previous DR-70D model. As a result, the unit boasts an equivalent input noise of -124 dBu or better.

The A/D converters, which convert analogue signals to digital, are made by Asahi Kasei Corporation and are equivalent to those used in the top models in the TASCAM DR series of linear PCM recorders. High audio quality HDDA circuits faithfully convert amplified audio to digital. Resolutions up to 96 kHz/24-bit are supported when recording six channels and 192 kHz/24-bit when recording two channels.

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

The DR-701D has four XLR/TRS inputs. The ability to adjust input levels independently and the availability of four channels make it possible to do separate miking of ambience and individual sound sources by utilizing two shotgun mics and one stereo mic. Since a 3.5-mm stereo input can be selected for channels 1-2 and the built-in omni mics for channels 3-4, an even wider range of mic setups are possible.

Multiband limiter and five-stage low-cut filter

A limiter function that automatically adjusts excessive input levels is included for all four inputs. A more natural sound quality is achieved because a multiband limiter is employed to affect only the frequency ranges that have excessive input. In addition, a five-stage low-cut filter can be adjusted to cut wind noise, rumble and other undesirable low frequencies.

Dual-recording function

Safety files can be created by recording two audio files simultaneously at different levels in case the main recording clips due to unexpected input overloading.

Record the same audio with a DR-701D and your camera

A dedicated connector is included to output mixed audio to the DSLR or video camera. This way, the same audio can be recorded by both the DR-701D and the camera. The output level has been made adjustable considering that input levels differ among camera manufacturers and input adjustments on cameras are limited.

Monitor the audio from the camera

A camera input makes it possible to monitor the audio from the DSLR camera during playback. By using this with the DR-701D monitor selection function, you can easily listen to not only the DR-701D but also audio from the DSLR camera.

Record ambience with your video camera mic

The external input can be used to connect video camera mics that have stereo mini jack outputs (like the TASCAM TM-2X). One possible setup is to connect a video camera mic to the EXT IN 1/2 input for recording ambience, and XLR shotgun mics to inputs 3-4. Plug-in power can also be supplied to the mini jack input for those mics needing it.

Slate tone generator makes aligning with video files easy

A slate tone generator is built-in to guide alignment in post production. By zooming into the waveform of both the camera and DR-701D audio, the sine wave can be perfectly aligned for exact synchronization. In addition to producing tones automatically at the start (or start and end) of recording, slate tones can also be produced at any point by the press of a button.

The HOLD switch makes it possible to disable unintended operation in order to prevent misoperation of the controls on the front panel, starting with the 4 gain adjustment knobs. Another example of the various design features for preventing misoperation are the handles on the left and right sides that protect the control surface while also enabling attachment of a shoulder strap. In addition, the gain adjustment knobs are designed so they are not moved with a slight touch, making unintended moves less likely. Other details implemented for ease-of-use include an LCD screen and LEDs that promote high visibility even under direct sunlight.

Use it as a standalone field recorder

The DR-701D can be used as a six-channel field recorder with four input channels. Attach a strap to the red handles for comfortable outdoor use. Whether hung around the neck or shoulder, the unit can be easily operated and adjusted.

Magnesium alloy for a lightweight, solid design

The unit is composed of a magnesium alloy that is very durable for a lightweight, but solid structure. While including abundant input connections, it was also designed for high mobility even when a camera support system or stabilizer is attached. Screw threads for mounting a tripod are included on the bottom of the unit, while a camera attachment screw and hot shoe (that can be removed) are included on the top of the unit. The DR-701D can be set up in a manner for the best handling. For example, it can be installed between a tripod and a camera, or attached to the top of the camera using a shoe mount.

Power can be supplied from a USB mobile battery

In addition to operation using 4 AA batteries, even longer operation is possible with support for power supplied from a mobile battery with a Mini-B USB port. The TASCAM BP-6AA battery pack is also compatible.
