  • Remote audio attenuator
    Patent number: 3983421
    Abstract: A remote audio attenuator in which a volume control variable resistor of the attenuator regulates a volume control variable resistor of a distant audio system with complete isolation between the circuit of the two volume control resistors, and with rapid response between the two control units. The attenuator employs a lamp controlled by a differential operational amplifier, with the lamp set to equally illuminate slave photoresistors, one or more of which serve as the volume control units of the distant audio system, and one of which is connected to a resistance bridge to provide feedback to the differential operational amplifier, the output of which is also controlled by the remote control variable resistor which is also connected to the resistance bridge.
