Abstract: An adjustable support stand is particularly adapted for securely positioning an electronic module, or modules, over a wide range of heights and tilt angles to facilitate the exercise of control thereover by an operator. The support stand includes a base and an open mounting rack of standard width within which the electronic module may be securely mounted. A manually controlled locking mechanism permits the tilt angle of the mounting rack and electronic module to be adjusted over a wide angular continuum. In one embodiment, a boom is mounted to an upper portion of the support stand for supporting a microphone as well as the mounting rack. In another embodiment, the mounting rack is coupled to an in-line rack support frame and is free to pivot vertically therein. The in-line rack support frame is mounted to an upper portion of the base and is free to rotate thereon in providing multi-axis displacement of the electronic module.
