Attention Court Reporters:

Have you heard claims from other manufacturers that their mics are the best? Try this mic system (and theirs if you like), and if you are not 100% convinced that this system produces stronger, clearer audio than any other microphone sysem, 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 8000 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 advanced active noise filters (which are defeatable if you wish) will greatly reduce unwanted ambient room noises from your recordings.

This microphone features amplified live audio monitoring with headphones (even when not recording!) to help you hear what is being recorded – so it works like an audio amplifier for you. Place your microphones around the room and hear every word!

There are no batteries in this system, so you never have to worry about dead batteries during that important trial or deposition! This system 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 system bypasses your computer’s internal soundcard and all of the audio processing is done right inside the sturdy aluminum case. This frees up processing power on your computer to run your software.

Need more convincing? Don’t take our word for it see what Eclipse Guru Keith Vincent has to say about it:

Keith Vincent’s court reporter review website (Eclipse)

This microphone system is capable of picking up all of the sounds in large room (range of approximately 100 feet) or it can pick up small area its up to you, because you control the amplifier power! It’s small size makes it perfect for situations where you don’t want to draw attention to the fact that you are recording audio right into your computer.

For multi-track recording, you can download Audacity instead.
