Two Channel Recorder for Stenomask Reporters

TASCAM DR-40XP
Two-Channel Stenomask Recorder Package

Your stenomask on one external channel. Your room microphone on the other.

The DR-40XP is a professional four-track recorder built around two independent XLR/1/4-inch external inputs. For the Martel court-reporter workflow, those inputs can record your mask and room microphone as separate left and right channels inside one stereo MP3 or WAV/BWF file. You can also use four-channel mode to add the recorder's built-in stereo microphones as an additional room-audio backup.

Stenomask is shown for connection reference and is sold separately. The Martel room microphone is included.

Keep the Familiar Mask-and-Room Setup With a New Professional Recorder

This Martel package is designed for reporters replacing discontinued Marantz PMD670, PMD671, PMD660 and PMD661 recorders. It preserves the essential workflow—one channel for the stenomask and one for the room—while adding 32-bit float recording, microSD storage, USB-C connectivity and optional four-track capture.

The DR-40XP is a modern alternative, not an identical copy of an older Marantz recorder. Its controls, menu system, memory card and connector layout are different.

Two External Channels Plus Two Built-In Channels When Needed

For everyday court-reporting use, record the two external inputs as separate left and right channels. For additional coverage, four-channel mode records the built-in stereo microphones and the two external inputs at the same time.

This gives you a flexible primary recording path plus an optional room-audio backup.

Two Combo Inputs on the Bottom

The two external inputs are XLR/1/4-inch TRS combo jacks located on the bottom of the recorder—not microphone jacks on the front.

No 3.5mm Microphone Input

The 3.5mm jack is a headphone/line output. A stenomask with a 3.5mm plug needs the correct Martel-approved adapter or connection system.

Phantom Power Is XLR Only

The recorder provides selectable +24V or +48V phantom power through the XLR portion of the combo jacks only. Use phantom power only with compatible microphones or approved adapters.

Stenomask Track

Connect your compatible stenomask to its assigned external input. Your dictated voice remains on its own side of the stereo recording.

Room-Audio Track

Connect the included Martel room microphone with the package connection hardware so the proceeding audio is captured separately.

Separate Left and Right Audio

The two sources are stored as left and right channels in a stereo file. Compatible transcription software can monitor, pan or isolate the channel needed during review.

MP3 Recording

Selectable MP3 bit rates from 32 to 320 kbps at 44.1 or 48 kHz make it easy to balance file size and audio quality.

Included 32GB card at 128 kbps:
Approximately 552 hours and 24 minutes of total two-channel stereo MP3 recording capacity.

Included 32GB card at 320 kbps:
Approximately 220 hours and 56 minutes of total two-channel stereo MP3 recording capacity.

32-Bit Float WAV/BWF

32-bit float recording gives you far more flexibility to correct levels later when speech is unexpectedly quiet or loud. It is available at 44.1, 48 and 96 kHz.

Included 32GB card:
Approximately 22 hours and 40 minutes in stereo at 48 kHz.

32-bit float is WAV/BWF—not MP3. The PEAK indicator still matters because true analog input overload can distort.

16-Bit or 24-Bit WAV/BWF

Standard linear PCM modes are available when you want uncompressed audio without the larger 32-bit float file size.

Choose 44.1, 48 or 96 kHz, with BWF support for professional file information.

Fast Recording Control

The large red recording control is easy to identify when a proceeding begins.

Independent External Levels

Use EXT INDEP. and the INPUT LEVEL buttons to adjust the mask and room channels separately.

Backlit Level Display

Watch the input meters, dB readout and PEAK indicator while checking both audio sources.

Pre-Record Protection

PRE REC can capture the two seconds of sound immediately before recording is activated.

Four Low-Cut Settings

Choose 40, 80, 120 or 220 Hz to reduce HVAC rumble, handling noise and other low-frequency sound.

Multiple Level Modes

Manual, limiter, peak-reduction and automatic-level options are available in supported recording modes. The 32-bit float mode uses manual level control.

Speaker + Headphone Monitoring

Review through the built-in mono speaker or monitor with headphones through the 3.5mm output.

Transcription Review Mode

Dictation Play adds Voice EQ, adjustable jump-back and jump-forward controls, and playback speeds from 0.5× to 2.0× without changing pitch.

Computer Connection

Use USB-C for mass-storage file transfer or as a two-input/two-output, 24-bit USB audio interface at 44.1 or 48 kHz.

Large-Card Support

Supports microSD, microSDHC and microSDXC cards up to 512GB. A 32GB card is included with this package.

Adjustable Built-In Microphones

The directional stereo microphones switch between focused X-Y and wider A-B pickup and handle sound levels up to 125 dB SPL.

Long-Job File Control

Add marks, divide WAV files and configure automatic file increments for easier management of long proceedings.

What Is Included

Stenomask and AA Batteries Are Sold Separately

The package includes the recorder and room microphone. Your stenomask is not included. The recorder can also operate from three AA alkaline, NiMH or lithium batteries when portable power is needed.

Use the Included AC Adapter for All-Day Recording

The DR-40XP can run from three AA batteries, but phantom-powered microphones, headphone monitoring and high-resolution modes use additional power. For hearings, depositions and courtroom sessions, AC power is the dependable primary choice. AA batteries can be kept available for portable operation or contingency use.

The Recorder Does Not Recharge AA Batteries

Connecting the AC adapter powers the recorder, but it does not charge batteries installed inside the unit.

How long will a 32GB card record in two-channel MP3?

At 128 kbps, the included 32GB card holds approximately 552 hours and 24 minutes of total stereo MP3 audio. At the highest 320 kbps setting, it holds approximately 220 hours and 56 minutes.

Does it have two independent microphone inputs?

Yes. It has two external XLR/1/4-inch TRS combo inputs. EXT INDEP. allows the external left and right levels to be selected and adjusted separately.

Are the stenomask and room microphone recorded separately?

Yes. In stereo mode, the two external inputs are recorded as separate left and right channels inside one stereo file. They are separate channels, not two unrelated mono files.

Does the DR-40XP record MP3 files?

Yes. It records MP3 at selectable rates from 32 through 320 kbps. It also records WAV/BWF in 16-bit, 24-bit and 32-bit float.

Is 32-bit float available in MP3?

No. The 32-bit float option uses WAV/BWF recording. MP3 uses selectable compressed bit rates from 32 to 320 kbps.

Does it have a 3.5mm microphone input?

No. Its 3.5mm jack is a headphone/line output. A 3.5mm stenomask or microphone needs the correct powered connection system or adapter.

Does the recorder have a built-in speaker?

Yes. It has a built-in mono speaker for playback monitoring, plus a 3.5mm headphone output.

Can it record four channels?

Yes. Four-channel mode records the built-in stereo microphones on one pair of channels and the external input pair on another, creating two stereo files.

Will my existing stenomask connect?

Some 1/4-inch stenomasks can connect through the combo jack, but compatibility depends on the mask's plug wiring and signal type. Other connections, including 3.5mm plugs, require the correct Martel cable or adapter. Confirm compatibility before ordering when the mask connection is uncertain.

Does the AC adapter charge the AA batteries?

No. The AC adapter powers the unit but does not recharge batteries installed in the recorder.

Is the stenomask included?

No. The package includes the recorder and Martel room microphone. The stenomask shown in the package image is sold separately.
