General Information:

The Sound Professionals mini mono microphones are small, mono microphones that can be plugged into any recorder (DAT, MiniDisc or analog) that supplies a bias voltage of between 1.5 and 10 Volts DC at the microphone input jack, commonly known as "plug in power". Many of the recorders on the market today include this feature. They can also be used with computers and laptops for recording.

When connected to your recorder or computer in this manner, these microphones are perfect for recording lectures, business meetings, and musical performances when an easy to setup and use microphone is required.

Sound Quality
The Sound Professionals microphone systems have an extended frequency response and a very natural and accurate sound, providing deep, solid bass, smooth midrange and clean highs. They have a very wide dynamic range, and will handle very high sound pressure levels without distortion or clipping. (See details above for more info). When combined with one of the battery modules, they are designed to operate into a nominal impedance of 10K Ohms.
