Description:

The SP-SPSM-4 is a Cardioid (Unidirectional) single point stereo microphone. Each side of the "T" consists of a high quality Audio Technica AT831 Deluxe Cardioid microphone, mounted on a flexible boom arm. This flexibility allows the arms to be aimed very accurately at the sound source to greatly reduce unwanted noise from the surrounding area. An optional removable microphone stand mount is available here that can be used to mount this microphone on a mic stand when desired.

This microphone differs from other types of single point stereo mics in that it offers a significant improvement in stereo separation due to the distance between the microphones and because of the flexibility in positioning of the mic cartridges.

In addition, there are several battery modules designed for this microphone that will give this microphone increased dynamic range and the ability to record loud sounds. More info on battery modules is located here.

Made in the USA.

General Information:

The Sound Professionals single point stereo microphones are small, stereo 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.

When connected to your recorder 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. For situations that do require wider stereo separation, we recommend the Mini Binaurals or Mini Cardioids.

Battery modules (power supplies)
In certain recording situations, you may need a separate power source for your microphones. Visit our Battery Module FAQ for more info on why you would want to use a battery module. All of the single point stereo microphones are compatible with any of our battery power modules. See the battery module page for more details.

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.
