ABSTRACT:
A sound system, particularlyuseful for isolating the signals from each of a plurality of different sources disposed closely together, such, as for example, from the components of a drummer's set-up of drums and cymbals. The system includes individual transducers associated with each of the drummer's units to provide separate and mutually independent signal sources. The signals from each source are transduced along an associated channel to provide a discrete path for each. Each of the channels includes a selectively settable tone control means for modifying the signals thereof. Finally, each channel includes means for selectively coupling the output of the associated tone control means to one or more of a plurality of devices applying "special effects" to the input signals thereto. In a system of the kind described means are carried by impact portions of each of the drummer's units so as to inhibit objectionable mechanical feedback into the transducer caused by prolonged vibration of the impact portion, and to reduce the sound level when played.
