Hi, Yes it is possible and even some TV"s feature this ..My Panasonic has this feature..You have to look at the specs to find it.. Sometime cable companies will adjust the overall sound level on a channel to reduce cross talk and co-channel interferrence..Air channels I reason will sometimes lower the audio level of the show so you have to turn up the volume..Then blast you with the commercial..(just my guess) As to a vague description of how it can be done is to use a resistive voltage divider but the lower leg is a FET ..There as you vary the gate voltage, the ratio is changed due to the changing drain resistance..This is a less elagant way to do it but you get the idea.. Good Luck, JP
