Xu Li, Elliot M Rubin, Xiaofeng Shou: Methods and apparatus for automatically synchronizing and regulating volume in audio component systems. Microtek Lab, Erik K Satermo, February 15, 2000: US06026168 (55 worldwide citation)

A signal regulator regulates an auxiliary signal based upon a primary signal scaled by an external amplifier. The signal regulator receives the primary signal with an unscaled level. Processing circuitry monitors the unscaled level of the primary signal. The primary signal is then output to the exte ...
