Double ultra-high gain Omnidirectional Boundary microphone – our best!

The Sound Professionals Boundary microphone pair is our very best microphone for Courtrooms, Depositions, Meetings and Lecture recordings and is hand-crafted in the USA. This ultra-high sensitivity microphone offers premium sound quality. This microphone will work with all Steno writers, Andrea USB soundcards and audio recorders that provide ‘plug in power’ between 2 and 12 Volts DC at the microphone input jack. Plugged into a USB microphone, it will extend the USB mic range and is perfect for picking up sidebar conferences, witnesses, etc.

This microphone is also perfect for recording lectures, business meetings, interviews, etc. The microphone element is omnidirectional, so it picks up sound in all directions equally. This microphone has an ultra-high sensitivity mic element for recording sounds ranging from extremely quiet to moderately loud sounds. It has a S/N ratio of 80dB for super low noise (hiss) and -24dB ultra-high sensitivity. Each microphone has a range of approximately 125 feet x 2 (depending on conditions).
