Thanks for the suggestions. The Behringer is way more comp0licated than I am looking for. I have a low-end analog receiver/amp because do not have the auditory discrimination to tell much difference between that and a high-end system. I'm looking for something where I can set the low-volume boost and high-volume limiter knees to what works for me and leaave tham at that setting. If I can find a cheap enough unit, I would buy one for both the DVD and TV amplifier inputs. I found a couple of microphone preamps ICs that I could build a circuit around but I do't really need any gain. Something that would take the TV and DVD audio outputs,compress them, and send them on to the amplifier at teh same average signal level.
