Cool, Smitty got a new DVD player and sound surround.
Well...no...but interesting reply!
If I were to take a guess, it looks like the Schmittenheimer is making a mixer w/preamp.
Some of that answer is getting in the parking lot of the ballpark. But, it's a little more involved than that.
What ARE you up to sir....
Well, I'm not ready for a full reveal, yet. I need to compete connectivity and actually test this out, as the idea may be a dismal failure!
By the way....that silver box is an audio digital signal processor. It can do mixing, audio routing, acoustic echo cancellation, automatic gain control, level control, input and output muting, and filtering and EQ on every input. It also features GPIO control, ethernet control, USB control, RS-232 control, and can even make a telephone call. And, it has a built-in 20 watt audio amplifier. It handles 24-bit at 48 KHz AD and DA conversion. It can handle audio inputs ranging from mic level sources, to consumer level sources, to professional sources. All inputs and outputs are balanced, but it can handle unbalanced inputs and outputs, too.
Funny thing is, I used to spec these out for projects. They used to run nearly $3000.00. Since this has been superseded by a newer model, this model is super cheap, even though it's only one generation old. I got this one used for $15.00 (Fifteen dollars!) on ebay.
But, that still doesn't tell you what I'm doing!
