Abstract: A remote control system for an audio system component. An intermediate circuit is connected into the audio system interposed between the component and system amplifier through standard input/output jacks. The intermediate circuits include a first controllable attenuator for volume control, and frequency selective controllable attenuators to provide for independent bass and treble control. Control of the attenuators are effected from a remotely located control panel. Provisions for coupling the control panel and intermediate circuit through existing standard house electrical wiring, and provisions for remote on/off control are also described.
