Installation instructions

New! Available exclusively from The Sound Professionals, this is the highest output (gain) stereo (can also record in mono) high-sensitivity, professional model channel USB Boundary microphone available, and is the best choice for court reporters when you need to put microphones in different locations. Cable length is 10 feet, but custom lengths are available - please call.

This is a high quality USB boundary microphone bundle, capable of picking up all of the sounds in large room (range of approximately 125 feet from each microphone) or it can pick up small area its up to you, because you control the amplifier power!

Attention Court Reporters:

Have you heard claims from other manufacturers that their mics are the best? Try this mic (and theirs if you like), and if you are not 100% convinced that this microphone produces stronger, clearer audio than any other microphone, we will gladly give you refund! This is the #1 choice for professional Court Reporters! Wondering why our microphone is $100 less than others claiming to be the best? So are we! In the past years, over 6000 Court Reporters in the USA have purchased Sound Professionals USB microphones (and all of our USB mics are made in the USA). Ask other professionals in your field they will tell you how good these microphones really are!

This microphone has an amazing amount of amplification and can produce recordings that sound three times as loud (strong) as other USB microphones. The difference in sound level and clarity is dramatic. The adjustable, advanced active noise filters will reduce unwanted noises from your recordings.

This microphone also has blue recording indicator light so that you know you are recording audio. No guessing! This microphone also features amplified live audio monitoring with your headphones (even when not recording!) to help you hear so it works like an audio amplifier for you.

You never have to worry about batteries running out on you during that important trial or deposition! This microphone was designed especially for the professional Court reporter and works with all Audio Sync programs.

Have you "upgraded" your computer recently and found that the audio in the new computer is not as good as your old machine? You are not alone. This microphone goes around your computer's internal soundcard and all of the audio processing is done right inside the microphone. This frees up processing power on your computer to run your software and will help the computer to run faster.

For times when you need to be discreet, you can plug the mic right into the computer's USB port (or USB hub if you are out of ports). Or, you can use USB cable to move the mic away from your computer it's up to you. This mic can work both ways for you.

4 out of 5 stars Good mic 10/12/2020
Reviewer: A viewer   from Boston
I'm still tweaking this mic, so not a 5 yet, but I'm sure it will eventually get to a 5. Much better than my last mic from a supplier who shall remain nameless. No more beeping in the background and sounds very good.
