Four-track recording made easy

Tascam's compact, handheld DR-40X lets you capture professional-quality recordings, and its versatile features are well-suited to musicians, podcasters, and other types of content creators. It has two built-in microphones and a pair of XLR/TRS combo jacks for four-channel recording. The DR-40X can record in MP3 and high-resolution WAV formats - including BWF (Broadcast Wave Format), used in professional media production.

Customize your recordings

The DR-40X lets you record in either WAV or MP3. You can set the resolution for WAV recording up to 24-bit/96kHz, and MP3 resolution up to 48kHz/320kbps. The mics can be positioned A-B to record a wide soundfield, or X-Y to focus on a single point.

Pro-level recording

The mics can handle high volume levels, all the way up to 125 dB SPL. Record your band's rehearsal and capture it without distortion. And they're sensitive enough to record a whisper.

In dual record mode, the DR-40X captures your main stereo signal, plus a second simultaneous version at a lower input volume level. If things suddenly get too loud, the take isn't ruined. You can replace clipped audio with the safety copy.

Versatile reconnections

The recorder's XLR/TRS combo jacks support mic-level and line-level input. You can connect the DR-40X to a mixer or an FOH (front-of-house) PA console. The mic preamps include phantom power for condenser microphones.

USB audio interface

Connect the DR-40X via a USB cable to your computer for live streaming or podcast recording. (Cable available separately.) It turns the recorder into a USB microphone that delivers finely detailed sound.

More great features

The recorder has three low cut filters, which are handy for eliminating low-frequency noises like the sound of wind or electric motors. A peak reduction function automatically adjusts levels to prevent clipping. The built-in screw hole lets you mount the recorder on a tripod. And there's a headphone jack, for monitoring.

Memory and battery life

The recorder has a microSD card slot. Use microSD memory cards to store up to 128GB of recordings. The recorder gets up to 17.5 hours of operation from three "AA" batteries (available separately).

General Features

Overview: The TASCAM DR-40X is a hand-held, portable stereo digital recorder designed for music, cinema, podcasting, field recordings, and more. You can make high quality 4-track recordings using the LPCM format, or a large number of recordings in MP3. The recorder features a slot for an SD/SDHC/SDXC card (sold separately) for storing your recordings. It has two microphones with adjustable angles, two Mic/Ext inputs, a mono speaker, and a line/headphone output. The DR-40X operates on three AA batteries (included), and weighs 7.51 ounces (not including batteries).

LCD Display: The DR-40X features a 2" (diagonal), backlit, monochrome LCD (128 x 64 pixels) which indicates recording and playback information. The recorder will display the elapsed or remaining recording time in hours, minutes, and seconds.

Date and Time: The recorder features a built-in clock. If you have set the time and date, information as to when a sound file was recorded is stored automatically with that file.

Microphones: The unit features two high quality condenser microphones mounted on the top of the recorder. The angles of the microphones can be adjusted to suit the recording situation. You can choose Clear Stereo Sound by angling the microphones in a closed position (X-Y position), or choose Wide Stereo Sound by angling the mics in an open position (A-B position).

Mic/Ext Inputs: Located on the bottom of the unit are two inputs for connecting external mics or an external device. These balanced inputs have locking XLR/TRS combo jacks (balanced), which can accept 3-pin XLR or standard 1/4" plugs. The built-in microphones and external inputs can both be used for recording simultaneously. This can be useful for recording a band directly off a mixing board, as well as capturing a live audience to be blended in. The DR-40X can be set to provide +24V or +48V of phantom power to both Mic inputs.

Low Cut Filter: The device features a low-cut filter that can be engaged to reduce noise, such as wind noise, during recording. The cut-off frequency can be set to 40 Hz, 80 Hz, or 120 Hz.

SD Card Slot: The DR-40X Digital Recorder features a slot for inserting an SD card. The recorder is compatible with SD cards from 64 MB to 2 GB, SDHC cards from 4 GB to 32 GB in size, and SDXC cards up to 128GB.

  • Note: An SD card is NOT included and must be purchased separately.

The maximum recording time using a 8 GB SD card is as follows:

File Format Recording Setting Capacity
16-bit 44.1kHz
24-bit 44.1kHz
44.1 kHz/48kHz 32 kbps
64 kbps
96 kbps
128 kbps
192 kbps
256 kbps
320 kbps

Formatting Memory Cards: Memory cards can be formatted in the unit to prepare them for use. You can choose a quick format, which erases all music files on the card and automatically creates new Music and Utility folders, as well as the DR-1.sys file that is necessary to use the card with the unit. Full formatting checks the memory for errors while formatting, and takes longer to complete than quick formatting.

USB: The DR-40X has a Micro-B 2.0 (High speed) USB port on the side for connecting the recorder to your computer for transferring files or for providing USB bus power (USB cable sold separately). With the optional TASCAM PS-P520E AC adapter (which plugs into the USB port), you can operate the unit on ordinary household current. The DR-40X is compatible with the following Operating Systems: Windows 10, Windows 8.1, Windows 7, and Mac OS Catalina, Mojave, High Sierra (10.13), and Sierra (10.12). The DR-40X also supports iPad iOS 13, 12, and 11.

Headphone/Line Out Jack: The DR-40X has a 3.5mm stereo jack for plugging in a pair of headphones, or for connecting to an external device or a powered monitor. You can listen to files played back or monitor the recording as it is made.

Battery Power: The recorder is powered by three "AA" batteries. You can use either alkaline (included) or Nickel-Metal Hydride (Ni-MH) rechargeable batteries. Battery life varies according to the recording format as follows:

Recording WAV Alkaline: 8.5-20.5 hours
Ni-MH: 8-17 hours
MP3 Alkaline: 9.5-18 hours
Ni-MH: 8.5-15 hours
Playback WAV Alkaline: 15.5-21.5 hours
Ni-MH: 13-17.5 hours
MP3 Alkaline: 16.5-17.5 hours
Ni-MH: 14.5-15 hours

Remote Jack: The recorder has a 2.5mm sub-minijack on the bottom (between the external mic jacks) for connecting a remote. The optional Tascam RC-3F footswitch remote or Tascam RC-10 wired remote can be used to operate the unit. The 3-pedal RC-3F footswitch offers assignable functions for the left, center, and right pedal. The RC-10 has 4 function buttons, as well as six control buttons (stop, play, rewind, fast forward, record, mark).

Tripod Socket: The DR-40X is equipped with a standard 1/4" tripod socket on the back so you can mount the recorder onto a tripod, if desired. A rubber Tilt Foot is included that can be attached to the tripod socket, preventing the mic from being too low when recording with the unit laying flat.

Recording Features

Recording Format: The DR-40X records audio files in WAV and MP3 formats. The unit is compatible with the BWF (Broadcast Wave Format) for WAV files. You can choose from the following recording options:

  • WAV/BWF: 44.1/48/96 kHz, 16/24-bit
  • MP3: 44.1/48 kHz, 32/64/96/128/192/256/320 kbps

Recording Modes: The recorder has five recording modes to choose from:

  • Mono: recordings are made in one channel
  • Stereo (Default): recordings are made of two independent left and right channels
  • Dual: recordings are made using one input source (mono or stereo pair) to create two files with different input settings. This mode captures a safety track at a lower level to avoid distortion. Either two mono or two stereo recording files are created.
  • 4CH: recordings are made using both the built-in mics and the external inputs to record two pairs of inputs as two files. Two stereo recording files are created.
  • Overdub: This recording mode adds new sounds to the playback file. You can choose Mix Overdub, in which the playback sound and input sound are mixed to create a new file, or Separate Overdub to create a new recording file with only the input sound.

Auto Tone: This function can be used to automatically insert a tone signal whenever recording starts and stops. The Headphone/Line Output jack can be connected to the mic input on a video camera or digital camera with Auto Tone capability. This allows the tones to act as guides when synchronizing the files in video editing software.

Recording Levels: After selecting the input (built-in or external), you can adjust the input levels to prevent recorded sounds from being distorted due to excessively high input signals, or from being inaudible due to excessively low input signals, compared to noise. There are three level adjustment functions:

  • Peak Reduction: The input volume is reduced automatically to an appropriate level when excessively high signals come in.
  • Automatic Level Control: The recording level is controlled automatically to increase or decrease the input level when the input signals are too small or too large. This mode is useful for recording at meetings. Manual adjustments to the recording level cannot be made.
  • Limiter: Engaging the limiter prevents distortion of sounds when excessive high input signals come in suddenly. This mode is suitable for live performances with large volume changes. You can adjust the level manually during recording.

File Names: Each time a file is recorded, a file name is assigned to the recording. The file name can be either a 6-character word or a 6-digit date (yymmdd format). You can set the word file name, while the date file name is automatically set using the unit's internal clock.

Overdubbing: Overdubbing allows you to play an instrument or sing as you play back a saved track and mix and record both sounds in a new file.

Marks: The DR-40X lets you place an electronic mark in a recording to identify specific points in the recording. Mark information is stored in the file with numbers between 01 and 99. Marks stored in a WAV file are BWF-compliant, and can be added automatically or manually. During playback, you can immediately move to marks in the currently selected file when paused.

Automatic Recording: When Automatic Recording (Auto Rec) is enabled, the unit will start and pause recording, renew files, and set marks automatically, depending upon the input signal level.

Pre-Recording: Pre-recording enables you to start recording up to 2 seconds before you press the Record button. This enables you to avoid missing the exact moment a recordable event begins.

Self Timer: Like a camera, the recorder's self timer lets you start a recording after a set period of time. Self timers can be set to 5 seconds or 10 seconds.

Edit and Playback Functions

Browse Screen: The DR-40X's Browse screen lets you view the contents of the Music Folder containing the audio files on the SD card. You can play or erase selected audio files, organize them into folders, and add tracks to the playlist.

Divide: A recorded WAV file can be divided into two at a specified position. This allows you to edit out unwanted portions of a track by placing them in a separate track and deleting them.

File Swap: Files recorded in 4CH or Overdub Separate modes can be swapped for other files. For example, in 4CH mode, a file recorded by the built-in mics can be swapped with a file recorded by external mics or equipment.

Playback Control: The Playback Control screen allows you to access some special playback control functions. You can playback a selected section of a track repeatedly (Loop Playback), or change the tempo of music without changing the pitch in a range from 50% to 200% normal speed (Variable Speed Audition, or VSA).

Playback Equalizer: You can choose from different sound types to enhance the sound quality of a track by using the Playback Equalizer (PlayEQ). The PlayEQ lets you make adjustments (+ or -) in the High (treble) Middle, and Low (bass) frequency ranges.

Level Alignment: If the playback sound is very small, the perceived overall level can be increased to enhance listenability.

Jump Function: During playback, you can press the play button to move back or forward a few seconds to hear a section of the track again. The Jump function is adjustable in the menu, allowing you to set the jump-back/forward time to 1-10 seconds (in increments of 1 second), as well as 30 seconds, 1 minute, 5 minutes, and 10 minutes.

Effects: The DR-40X has built-in effects that can be applied to the input signal during recording and practice, or applied to the output signal during playback. You can choose a preset effect type and the level of the effect (0-20). The Effects Preset list includes:

  • Hall 1: A bright reverb in a large hall-like space.
  • Hall 2: A warm reverb in a large hall-like space.
  • Room: A reverb in a small indoor space.
  • Studio: A reverb in a studio-like space.
  • Plate 1: A bright plate reverb.
  • Plate 2: A warm plate reverb.

Tuner Function: You can use the DR-40X to precisely tune an instrument. You can calibrate the tuner by adjusting the reference tone (A) between 435 Hz and 445 Hz (in 1 Hz increments). The Tuner displays the mismatch between the tone of the musical instrument you are tuning and the reference tone. You can adjust the input level, if needed.

Note: The tuner can only be used with the built-in mics.

Mixer Function: The recorder has a mixer function that allows you to set the level of effects, stereo balance, and volume level for each channel. You can adjust the following values:

  • Send: Adjusts the send level of the selected effect is used on the signal (0 to 100)
  • Pan/Balance: Adjusts left-right balance (Left 12 - Center - Right 12)
  • Level: Adjusts volume level (0 to 100)
