Abstract
The sound reproduction equipment is used to provide sound reproduction recordings to several listeners. Each listener may choose any one of the recordings by automatic selection. The equipment has a sixteen recorded voice channels. Each channel has a pre-amplifier which supplies a bus line. The bus lines are connected to interconnecting units in turn connected to listening units. The interconnecting units are located near the pre-amplifiers. They comprise two eight-channel multiplexers, a binary counter, a pulse counter and a voice amplifier. The listening units have a telephone type dials for selecting the appropriate channel. They also have a set of earphones.
