DM4 4-Channel Courtroom Recording Software & Transcriber Kit
Record the judge, witness, and attorneys on separate channels so playback is easier, transcription is clearer, and the speaker you need can be isolated when necessary.
This complete Martel package includes DM4 courtroom recording software, a USB 4-channel mixer, four professional court microphones, four 10-foot cables, four microphone stands, one monitoring headphone, and one hard shell case.
4 Separate Recording Channels
4 Professional Court Microphones
48V Phantom Power
Headphone Monitoring
Remote PC Support Included
One Room Microphone Can Make Courtroom Playback Hard
Courtrooms are difficult recording environments. The judge may be at the bench, the witness may be across the room, and attorneys may speak from different tables. One room microphone can make it hard to hear who said what during playback.
The DM4 package gives each main speaking area its own microphone channel. During transcription, you can listen to all channels together or isolate the judge, witness, or attorney channel when you need more clarity.

Recorder and Transcriber in One Workflow
```DM4 software is designed as a 4-channel recorder and transcriber in one. Record the proceeding, then use the same workflow for playback and transcription.
- Record and play back four tracks.
- Listen to all four channels together.
- Isolate one channel when one speaker is hard to hear.
- Create a combined audio file for outside transcription workflows when needed.
- Use your preferred secure file transfer method when sending audio to an outside transcriber.
DM4 Mixer Features That Help Court Reporters
```4 Professional Microphone Inputs
Connect up to four compatible XLR microphones directly to the mixer, with each microphone assigned to its own input.
48V Phantom Power for Compatible Mics
The mixer provides switchable 48V phantom power for compatible Martel courtroom microphones that require phantom power.
Individual Gain Controls
Each microphone input has its own gain control, so the judge, witness, and attorney microphones can be adjusted separately.
Signal and Clip Lights
Signal lights help confirm that sound is reaching each channel. Clip lights warn when a channel is too loud and should be turned down.
Pad Buttons for Loud Inputs
Pad buttons help reduce the input level when a source is too loud, giving you more control during setup.
Live Headphone Monitoring
Monitor the microphones with headphones while recording, so you can confirm the courtroom audio is being captured before and during the proceeding.
Zero-Latency Direct Monitoring
The direct monitoring mix control lets you hear live microphone audio without waiting for computer software processing delay.
Mono or Stereo Monitoring
Use mono monitoring when you want all microphones centered in both ears during setup and recording checks.
High-Resolution USB Audio Hardware
The DM4 mixer uses high-resolution USB audio hardware capable of professional digital recording. Martel configures practical settings for courtroom use.
Powered USB Mixer Design
The mixer connects to the computer by USB and uses its own power source for a serious courtroom recording setup.
Playback and Main Output Options
Headphone, main output, and playback output options help with controlled monitoring and review.
Security Lock Slot
A built-in security lock slot is useful for courtrooms, offices, and agencies that keep the mixer in a fixed location.
Built for Transcription
Four-channel audio can make a major difference during transcription. Instead of struggling with one mixed room recording, you can focus on the channel where the speaker was closest to the microphone.
- Isolate a soft-spoken witness.
- Review the judge, witness, or attorney channel separately.
- Listen to all channels together for normal review.
- Create a combined file for outside transcription workflows when needed.
Remote PC Support Included
Court reporters should not have to fight with audio settings alone. Martel can remotely help configure the computer, select the correct audio input, check the microphone channels, and help you complete a test recording.
- Remote PC setup assistance included.
- Help selecting the correct DM4 recording input.
- Help confirming the four microphone channels.
- Designed for court reporters, clerks, and courtroom recording workflows.

Before You Start a Legal Recording
Recording rules vary by court, agency, state, workplace, and proceeding. The user is responsible for confirming that recording is authorized and permitted before recording.
Always complete a short test recording and play it back before the official record begins. Confirm all microphones, all channels, 48V phantom power, computer power, file saving, and playback.
Important Compatibility Notes
```- DM4 courtroom recording software is designed for compatible Windows computers.
- Computer is not included.
- For four separate tracks, the software must be set to use the four-channel DM4 input.
- Not every basic audio program records four independent channels. Use DM4 software or compatible multichannel recording software when separate tracks are required.
- 48V phantom power should only be used with microphones designed for phantom power.
- For larger courtrooms, Martel can configure compatible microphone expansion options when appropriate.
- Always make and play back a test recording before the official proceeding starts.
