摘要:
A boom stand adapted to support an electroacoustic device is constructed from a base, pivotal boom, stand elevating the pivotal boom, and a stacking counterweight. The stacking counterweight includes a terminal weight having a generally cylindrical body longitudinally terminated with a threaded coupler adapted to operatively couple with a threaded coupler on the boom, while aligning the terminal weight longitudinally co-axially with the boom. One or more medial weights having a generally cylindrical body and appropriate threaded couplers can be inserted between the boom and terminal weight. Each of the medial and terminal weights are preferably shaped to be adequately grasped by a person's palm and finger portion of a hand clasping about the longitudinal axis, and are thereby adapted to operatively permit manual rotation about their longitudinal axes.
