Hi all! My name is Greg, located in St. Louis MO- USA. I am a Security and Fire Alarm / Low voltage technician, and have been for nearly 20 years. I am trying to find a circuit to build that could best be described as an automatic volume control, or maybe a small, simple version of a compressor/expander used in pro PA systems to control/even out levels from microphones.
What I want it to do is control volume levels from my entertainment system to put a stop to the annoying practice of cranking up the audio levels of commercials that blow people out of their chairs. I would like it to boost the output level slightly to match levels from other components in my system. (the output of the cable box is lower than cd player, hd radio tuner, computer input, etc.) I have to remember to decrease volume on amp before switching to radio tuner during a commercial, or I blow myself out of the chair.
Apparently, there is legislation before our government to outlaw this practice, but I'm not holding my breath on this! Does anyone have any ideas, as I'm sure someone smarter than me as built one!
