MARTEL DM246 · RECORDING PACKAGE
Four omnidirectional microphones for a shared-room setup.
Build a tabletop courtroom or hearing-room recording setup around the Martel DM246 V2 and four omnidirectional microphones. This package includes a 32GB memory card and the T147 transcription kit, connecting four-channel recording with controlled playback and review.
Pickup around the microphone
Omnidirectional microphones receive sound from around their position. Place them close to the participants they serve and away from avoidable table noise, fans and loudspeakers.
A complete review station
The included T147 software, USB foot pedal and headset support a compatible DM246 transcription workflow. Channel selection helps the listener compare recorded microphone positions.
DM246 recording features
- Four separate WAV filesEnable all four channels in MONO mode to record a separate WAV file for each channel.
- Automatic file splittingDuring a long session, the recorder can start a new file at 2 GB and keep recording without a pause.
- Low-cut filterTurn on the low-cut filter to reduce low-frequency rumble.
- LimiterTurn on the limiter to help control sudden loud peaks.
- HOLD switchEngage HOLD to help prevent accidental button presses during a session.
- Date-based filenamesChoose date-based filenames to identify recordings by the day they were made.
Plan coverage around the table
Map the participants and choose four useful pickup positions. Keep a written channel map so the reviewer knows which microphone served each area. Use a saved test with people in their normal seats to assess speech level and background noise. Room size alone cannot establish reliable coverage.
Choose pickup style for the way people speak
An omnidirectional microphone can suit people speaking around a shared position. A directional microphone can be useful for a fixed speaker when it can be aimed appropriately. Compare the four-directional-microphone package against the seating plan before choosing.
Carry separate channels into transcription
Transfer the complete recording set and keep an untouched original copy. T147 can select supported channels individually or together. Because one microphone may hear several participants, a channel label identifies a position rather than proving a particular speaker.

Questions before you order
Which microphones come with this package?
Four omnidirectional microphones are listed in the package contents. They are a different configuration from the four-unidirectional-microphone package.
Does this package include the transcription kit?
Yes. The T147 kit provides transcription software, a USB foot pedal and headset for supported DM246 files.
What size memory card is supplied?
This package ships with a 32GB memory card. Check recording settings and available space before each session.
Will one channel contain only one person?
That depends on microphone placement and who speaks near it. An omnidirectional microphone can capture several people. Separate recording channels do not automatically isolate individual voices.
