So there is an old add-on, made by the original AR corp, and I have it running! good luck finding one! (last time I saw one go by on Ebay it was costly) Has stereo, IR conrol, some souce switching, and is a little black box about 8X6X1.5 inches.
Of more interest is a full set-up control for 6- Ch sources. Virtually everything in production relies on digitzing the signal and then selecting levels oout of the master chip. Analoge controls really don't exist, much.
In my case I have a sony DVD which outputs DTS, DVD 5.1, and SACD 5.1 all out of RCA's I (a) don't want to re-digitze my signal, and (B) won't pay like $1800 for a B&K Pre to give me a hookup. So what to do?
There is the analog devices chip 8400 and family which gives a true analog pot, and can be cascaded for as many channels as you want. Problem is it takes standard serial input data and I dont know how to program this.
What is VERY INTERESTING is a new device I found (for five bucks BTW), which is a remote control for a computer interface, made by hewlett Packard. there is an infrared reciever to it, AND IT OUTPUTS SERIAL DATA. So there we have it. can I figure out how to decode and tweak all this? No. Any hints?
I have the name of the fellow who was selling the remote.. He should be able to come up with a lot more of them.
Oh Yeah-Hi - I'm new here.
