T147 4-Channel Transcription Kit for DM246 Courtroom Recorder

Review the channel you need. Keep the whole exchange in context.

The Martel T147 kit brings four-channel transcription software, a USB foot pedal and an ultralight headset to a compatible DM246 playback workstation. Select an individual recorded channel or a combination of channels while you listen and prepare the transcript.

What channel selection helps you do

A microphone near the witness may capture a passage more clearly than a microphone across the room. T147 lets you compare the supported recorded channels without discarding the surrounding exchange. A channel represents a recorded source or position, and may contain more than one person.

Channel selection cannot separate voices already mixed together in one channel, restore missing speech or prove speaker identity. Keep the original recording and use the channel map supplied with the files.

Foot-pedal playback and adjustable backspace

Use the USB foot pedal to control playback while keeping your hands at the keyboard. Adjustable backspace lets you replay a short lead-in when restarting. Test the pedal, headset and application together using an actual sample from the recorder before beginning a job.

Match the software to your workstation

• The current listing identifies Windows 10 and Windows 11 compatibility.
• The current version supports Infinity USB2 and USB3 foot pedals.
• The software is supplied as a digital download. This full kit also includes the listed physical pedal and headset.
• Confirm the recording format and channel files before relying on multichannel playback.

Already have suitable playback hardware? Compare the T147 software-only license and check compatibility with your existing pedal before ordering.

From recording to transcript

Copy the complete recording set into a clearly identified case folder. Preserve the original and use a working copy for review. Open the supported channel files, confirm their sequence and rehearse channel selection at a passage where different microphones can be heard. Record useful timestamps and channel notes so another reviewer can reproduce the same listening check.
