AEA Stereo Microphone Positioner SMP Shop all AEA Microphones

The AEA Stereo Microphone Positioner (SMP) was designed specifically as a device for mounting a stereo pair of Coles 4038 ribbon microphones, but the bar will support microphones for virtually any manufacturer — even the heavy large diaphragm condensers that ordinarily will not fit on a conventional stereo bar.

The SMP consists of a sturdy one-inch wide hard-anodized aluminum bar and three microphone slid- ers. The bar is available in three sizes, 17-inches 1 meter and 1.25 meters, and is engraved across its length in 2.5-cm increments. With zero at the center, these markings designate the distance between the sliders, with special markings to indicate the 17-cm spacing unique to the ORTF stereo system. The sliders are marked around the circumference at 0°, ±30°, ±45°, and ±55°. These represent included angles of 60°, 90°, and 110° respectively between the microphones, and may be used to facilitate exact and repeatable positioning of any conventional stereo perspective. Each slider is fitted with two thumb- screws to secure it onto the bar.

Extra-wide locking rings are provided for each slider, and one female threaded coupler is included to allow the SMP to be mounted on a microphone stand or boom.
