The Martel DM246 V2 recorder is known worldwide for reliable, secure and fast digital court recording solutions for Courts, Attorneys and Court Reporters.

Uni-directional microphones are used when you need the clearest audio possible. You place them directly in front of the person speaking, and all other noises are prevented from ending up on the recording. Also included is the transcription kit, which contains a USB foot pedal, headset and 4 track transcription software.

The Martel DM246 V2 is the latest generation of 4 track/channel court room recorders. It is the direct replacement for the discontinued Sony BM-246 and Lanier Advocate 4 courtroom recorders.

The Martel DM246 V2 Four Channel Recorder consists of a special voice recording system that will capture every low volume voice, even in a noisy courtroom environment. The DM246 V2 has real-time confidence monitoring via headphones and "live" VU meter graphs, knob individual gain, and monitoring controls. Additionally, it has the ability to control each channel individually, isolating the microphone you want to hear by itself. It has AC and battery backup operation, plus built-in microphones that make it the worlds' only reliable 4 channel recorder available today for courtroom recording.

bonus case

We combined state-of-the-art digital courtroom recording to make your life simple. It works just like a tape recorder, just plug in microphones and hit record. 

Tired of computer recording software that doesn't work, or have errors causing you to lose the entire record? We have the non-computer solution. Never worry about windows errors while recording, since it isn't a computer. Numerous Major Court Reporting Firms in Washington DC place large orders to outfit their reporters who cover congressional hearings.

The DM246 V2 was created specifically as a replacement for your 4 track court tape recorders. It has several key distinct advantages to Court agencies: Records 4 separate tracks of audio. Burns directly to a DVD for archiving. Record 22 hours of 4 track audio on a 32GB SDHC card.

Voice Writers are using the DM246 V2 also. You can record the mask on channel 1 and the deposition or courtroom on the other 3 channels. Since you record in standard .wav format you can easily load the channel one into a voice recognition software such as dragon and get high accuracy voice recognition.

Today there is only one stand alone Digital 4 channel court room recorder with the ability to cover an entire court room. You can add up to 8 separate microphones into the DM246 V2 court room recorder. We must stress that we are making only very limited quantities

    Posted by Margaret A. on 6th Feb 2019

    I look at court reporting software for recording and it was $9000.00. So I ordered the DM246 from Martel it was only $1400. Huge savings. So I just ordered my second DM246 system and expanded my court reporting business.

    Sony bm246 replacement is the DM246 courtroom recorder it also replaces the Lanier advocate

    Posted by Wendy on 5th Aug 2014

    A great replacement for our sony bm246 courtroom recorder. If you use the Lanier advocate 4 channel recorder the DM246 is the exact replacement but its digital. The definition of digital means it recorders the audio to a SD memory card not a tape anymore. This has huge advantages, like storage on a server for easy retrieval. The audio quality is 10 times better. But if you have used the Sony bm246 4 track recorder you know it weighs a ton. It like lifting a elephant into the courtroom. The dm246 is small and weighs less than a pound. It fits nicely into my fancy purse.

    Take it from me a non-pc based courtroom recording system is the best choice

    Posted by Vicky on 16th Jul 2014

    All I have to say about software courtroom recording systems or solutions is windows errors or viruses. Ask your self do we have a IT person in the courtroom who can jump right on the computer and fix it within minutes so the judge doesn't get mad. Well you know thats not the real world. Call the IT department and in 2 days someone will come over. Thats why our IT person recommended the DM246 courtroom recording system. Its as reliable as you microwave oven. Runs on linux just like your over. Reliable and simple is the answer for our state court system.

    Digital Courtroom Recorder replacement is the DM246 multi-channel Courtroom Recorder solution

    Posted by Magnus on 6th Jul 2014

    If you are thinking about PC Courtroom Recording system do not buy a software system. The multi-channel Courtroom Recording is better done on a stand alone machine. The Computer Courtroom Recorder runs on windows and is not reliable. Digital Courtroom Recording needs a technology you can depend on like the DM246 multi-channel Courtroom Recording unit. When evaluating a Digital Court Recorder you must think about how simple it is going to be to operate it. If you do not have access to a onsite IT department then operating a pc courtroom recorder is not for you. You will need tons of computer help with software solutions that use a pc software court recording system. My advice is to go with a simple stand alone recorder like the DM246 system.

    We started last year with one of the DM246 Courtroom recorder packages. We liked it so much we now have over 12 of them in the courtroom system. The research information that Martel sent me made all the difference. The IT department was trying to replace the court reporter or clerk with an expensive courtroom software package. We tested them and no one could figure them out and they had software glitches. I was so happy to find the DM246 COURTROOM RECORDER because of the price and its so simple. I would recommended the courtroom recorder to everyone. Courtroom Recording Solutions made simple. Searching for courtroom recorder? Read this page and the news.
