ABSTRACT:
A noise-reduced stage lighting system has a motor having an output shaft driving a moving part of a stage lighting device, e.g. pan and tilt functions. An anti noise coupling is used to attenuate the noise produced by the assembly. An interface surface is formed with no metal connections between the noisy motor and the relatively quieter downstream components.
