Thomas,
Those processors are long gone. I do still have the software for it. Pretty sure because this very post is out on the interwebs, I cget an email from someone about every 6 months asking for it. Someone even bought me a pizza for it once...(paypal'ed me pizza money)
If all your are looking to do is sum to mono, you just need some resistors. In order for something with a transformer to work correctly it needs to drop to mic level.
I am not getting random tappatalk emails but random notifications. I have 12 new notifications 6 hours into today. I use Tapatalk so I would prefer that stay. It was a sad day when that other place dropped support.
What I don't get, is it seems like when something stops working on that other forum, no one cares. Email alerts stopped working, Tapatalk broke, no one cares.
The cut off has already happened in nearly all markets. Some for years now.
Apparently portions of Vermont still have yet to be cut off. You can find the time lines per market here...
It is the final... there are no other drawings unless you make your own. If you actually read the posts... which I guess no one does anymore... you will know the items you question are left up to each builder.
