Tascam DR-40X Four-Track Audio Recorder/USB Audio Interface

The Tascam DR-40X Four Track Audio Recorder/USB Audio Interface features four-track audio recorder for cinema, music, podcasting and any other application. This audio interface has an easy-to-use compact design with a high-performance feature set and versatile audio I/O, all to produce professional content. The layout of the DR-40X has been revamped to be quick and easy to work with one thumb. Operations like recording, adjusting levels, deleting bad takes and adding markers are just a button press away. The Menu display supports 10 different languages and has an ultra-long battery capability. Also, it can be powered by a USB mobile battery as well for super long extended use.

Line Level Input for Live Capture

The Tascam DR-40X Audio Interface features dual Neutrik XLR/TRS combo jacks that support both mic-level and +4dBu line-level. These inputs can accept balanced microphone or line level from Mixers or the FOH console. The microphone preamp includes +48V phantom power and plenty of gain for detailed recordings with condenser microphones, as well as electret type microphones. Using the stereo built-in microphones, you can capture ambient sound of the audience while recording direct from an external console, which is ideal for capturing live performances.

Versatile Four-Track Recording

In addition to normal stereo channel recording and dual recording mode, the DR-40X has 4CH Mode that can record two different stereo feeds simultaneously. The combination of the sources are flexible; recording the built-in microphones along with a pair of external Mics such as close-up and ambient microphones, or recording the built-in Mics along with a balanced line input such as the feed from a mixer along with the sound in the room.

Wide Covering Range

The DR-40X Audio Recording Interface allows high-quality recording with its stereo built-in condenser microphones. Every detail is captured from small whispers to loud sounds up to 125dB SPL. These built-in microphones are adjustable unidirectional microphones for recording in an X-Y pattern for tight stereo imaging or in an A-B pattern for a more ambient recording.

Turn Your Room into a Studio

When connected to a PC using USB Audio interface mode, the DR-40X becomes a tool for voiceover work, live streaming, and songwriting with studio-quality audio. It features built-in microphones that work as USB microphones. You can easily write down what you hear with this device. In addition to its capability to capture crisp voice recording, the DR-40X Interface can help you with its Jump back function, variable Speed function and equalizer preset for human voice.

Multiple Recording Modes

Film-makers and videographers often experience sudden audio volume spikes during filming. An actor could suddenly scream, or a documentary subject could do almost anything. The DR-40X Audio Interface has a dual recording mode that captures a copy of your take but at a lower level, as a safety track in case of sudden distortion. Also, auto recording function can detect the sound input signal level and automatically start recording. The pre-recording function with up to 2 seconds pre-record provides fail-safe protection.

Overwrite Mode

If you don’t like the last part of a phrase you just recorded with your guitar, or if you change your mind and want to rephrase narration, the Overwrite mode is exactly what you need. The Overwrite mode allows you to punch-in recording from a desired point. It is destructive editing with one level of undo.

Nondestructive Overdubbing

The overdubbing function allows for overdub recording while playing a previously recorded file. This allows you to record other parts such as a guitar solo over a recording previously made such as at a rehearsal studio. Overdubbing creates a new file, leaving the original file unaffected, making it easy to re-record.
