A compact 360° tabletop boundary microphone built for depositions, courtrooms, meetings, public hearings, stenowriter audio, and professional recorder setups where clear voice pickup matters.
The Audio Grabber is a low-profile boundary microphone designed to sit on a table and pick up voices from the room. Its 360° pickup pattern helps capture people speaking from different directions, making it useful for legal depositions, meetings, interviews, conferences, public hearings, and group discussions.
The Audio Grabber does not require batteries. It is designed to receive microphone power from a compatible digital recorder, stenowriter, mixer, or microphone input that supplies the correct plug-in power.
Daisy-chain microphones are designed to connect in a series, like links in a chain. Instead of running a separate cable for every microphone, you can place multiple Audio Grabber microphones down a table and connect them together for wider room coverage.
This is especially useful when one microphone input needs to capture several people seated across a larger space. Each microphone adds another pickup point closer to where people are speaking.
Connect the first Audio Grabber to a compatible recorder, stenowriter, mixer, or microphone input that supplies the proper microphone power.
Connect up to 6 Audio Grabber microphones to compatible Luminex and NexGen writers for expanded stenowriter audio coverage.
For larger professional setups, use up to 16 Audio Grabber microphones when connected through the Martel Court Reporter Mixer system.
The Audio Grabber is useful anywhere multiple voices need to be recorded clearly from a table or shared room. It gives you a practical way to add more pickup points without using battery-powered microphones.
Place microphones down the table to help capture attorneys, witnesses, and other participants from multiple positions.
Useful when speakers are spread out and a single microphone may not be close enough to every person speaking.
Use up to 6 Audio Grabber microphones with compatible Luminex and NexGen writers when you need more pickup points for court reporter audio.
When people are seated around a long table, one microphone may be too far away from some speakers. Audio Grabber microphones let you place pickup points closer to the voices you need to capture.
Each Audio Grabber can be part of a daisy-chain layout, allowing the microphones to be placed where people are actually speaking. This helps create a cleaner, more flexible recording setup for meetings, depositions, conferences, courtrooms, and stenowriter audio.
Use up to 6 Audio Grabbers with compatible Luminex and NexGen writers, or up to 16 Audio Grabbers with the Martel Court Reporter Mixer system.
The Audio Grabber is designed for compatible digital recorders, stenowriters, mixers, and microphone inputs that supply the correct microphone power. Always confirm that your recorder, writer, or mixer supports plug-in power for external microphones.
Works with compatible digital voice recorders from brands such as Sony, Olympus, Philips, and other recorder setups with the proper powered microphone input.
Connect up to 6 Audio Grabber microphones to compatible Luminex and NexGen writers for expanded court reporter audio pickup.
Use the Martel Court Reporter Mixer when you need a larger professional chain with up to 16 Audio Grabber microphones.
The Audio Grabber is compact, low-profile, and designed to sit neatly on a table in professional recording environments.
