Abstract

Multichannel signal processing system comprising a possibility for simultaneous storing of the regulation or control state of various control or regulation units. It is provided a set of control units (U1, U2... Un) similar to potentiometers and receiving each a signal to be processed, a memory CMOS (2) wherein informations are stored representative of the states of all the control units and a micro-computer (1) interconnected between these control units and the memory to control the storing of a set of satisfactory regulations and, subsequently, to position instantaneously the control or regulation units in a combination stored in the memory (2). Application particularly to sound restitution unit.
