Ultra-High Gain Miniature USB Omnidirectional Microphone/Headphone amplifier with 3 port USB hub built-in

Available exclusively from The Sound Professionals, this is a powerful, high output, high-sensitivity, professional ultra high-gain USB microphone with a 3 port USB 3.0 hub built in. It’s a great choice for court reporters, musicians, students, business people, voice recognition purposes, Skype communication, VOIP and Podcasting anyone that needs to get high quality audio into computer and can use a few extra USB ports, too!

Attention Court Reporters:

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.

This microphone features amplified live audio monitoring with your headphones (even when not recording!) to help you hear what is being recorded – so it works like an audio amplifier for you. With the addition of an inexpensive extension microphone, you will be able to hear *and* record sidebar conferences with ease!

There are no batteries in this microphone, so you never have to worry about dead batteries 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 bypasses 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.

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 either way.

This microphone is capable of picking up all of the sounds in large room (range of approximately 80 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.
