The new solid-state Volumax , like its companion-piece, the CBS Laboratories' Audimax*, is a tool to help the broadcaster achieve maximum program power within appropriate modulation limits. Designed primarily for use with well-controlled average input levels such as Audimax provides, Volumax replaces conventional peak limiters for the prevention of carrier overmodulation by instantaneous program peaks. With conventional peak limiters, the broadcaster has to choose between two evils: either program level must be reduced so that limiting of peaks will not be drastic enough to cause distortion and "pumping"; or this audible distortion must be tolerated.
