DR-701D 6CH Compact Audio Recorder for DSLR Cameras

Product Features

• Compact, professional-grade audio recorder designed to be used in combination with a DSLR camera (also usable as a standalone field recorder)
• Uses an SD/SDHC/SDXC card as recording medium
• Recording at 44.1/48/96/192 kHz, 16/24-bit, WAV/BWF format (192 kHz only for two-channel recording)
• High-quality recording inputs through Tascam original High Definition Discrete Architecture (HDDA) microphone preamps
• Up to six recording channels (4 channels + stereo mix)
• Dual recording function allows two files to be recorded simultaneously at different levels (–1 dB to –12 dB)
• Recording levels can be adjusted independently for inputs 1–4
• Two built-in omnidirectional microphones
• Four XLR/TRS combo inputs support +4 dBu line level and phantom power (+24V/+48V)
• +24 dBu maximum input level (20 dB headroom)
• 64 dB gain (maximum)
• Additional unbalanced input for channels 1 and 2 (stereo mini jack) supports mics that require plug-in power, allowing the input of video mics and other high-output mics
• Selectable mid-side decoding for use with MS microphone setups
• Selectable delay to eliminate time lags caused by differences in the distances of two microphones (±150 ms)
• Five-stage switchable low-cut filter conveniently reduces unwanted low frequencies (40/80/120/180/220 Hz)
• Multiband limiter automatically adjusts input overloads (stereo-linking possible with inputs 1 and 2)
• Trim settings of input channels 1–4 can be displayed
• Built-in mixer enables pan and level adjustments as well as solo monitoring and can output a mix of four channels
• Trim controls can be grouped to allow the levels of multiple channels to be controlled simultaneously
• Audio mixed by the DR-701D can be output to a DSLR camera
• Camera input enables convenient monitoring of audio from a DSLR camera
• Clock and starting/stopping recording can be synchronized with a camera using the HDMI input (depending on type of camera)
• The recorder’s audio signal can be sent to an external recorder using the HDMI output
• Timecode can be input through the TC IN connector and recording start times added to files
• Built-in timecode generator (RTC) allows recording start times to be added to files even when there is no timecode input
• Slate tones can be added automatically or manually to simplify synchronization of video files when editing
• Mark function allows up to 99 points to be added to a single file (mark information can be used in software that supports BWF)
• A new file can be created during recording (manually or by file size)
• File name format can be set to use a user-defined word or the date
• Resume function remembers the playback position even when the unit is turned off
• Cascade function using HDMI connections allows DR-701D transport and monitoring operations
• Tone generator is convenient when adjusting the relative levels of different equipment
• Headphones jack with 2 × 50 mW maximum output
• High-quality audio output through a line output jack separate from the headphones jack
• Hold switch prevents misoperation
• Transport and SLATE buttons made of rubber to suppress noise during operation
• 128 x 64 pixel LC display with backlight
• LED lights are visible even in direct sunlight
• USB 2.0 port for high-speed transfer of files to computers
• Micro-B type USB cable included
• 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 strap
• RC-3F foot switch and RC-10 wired remote control can be connected (both sold separately)
• Operates on four AA batteries or rechargeables, USB bus power, optional AC adapter (Tascam PS-P520E), or optional external battery pack (Tascam BP-6AA)
