The AEA Stereo Microphone Positioner (SMP) was first conceived as a device for mounting a stereo pair of Coles 4038 ribbon microphones. However, it soon became evident that we could design it to provide a secure and versatile support for microphones from almost any manufacturer — even the heavy large diaphragm condensers which ordinarily will not fit on a conventional “stereo bar”. The SMP consists of a sturdy one-inch wide hard-anodized aluminum bar with a non-reflective matte black finish and three microphone sliders. The bar is available in three sizes, the SMP-17(17 inches), the SMP-1M(one meter) and the SMP-1.25M(1.25 meters). The bar 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 degrees. These represent included angles of 60 , 90 and 110 degrees 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 microphone positioning 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. For more complex microphone arrays, additional sliders may be ordered separately (AEA part no. SMP-S ). Multiple SMPs are combined to create the AEA Mini Tree, "Decca Tree" and Super Tree arrays. |
