Some schematics of interest from Analog Devices & others

[Jim Zuehsow]

I just added a few schematics from the Analog Devices Audio/Video Reference Manual which may be of interest. Included is the Morgan Compressor/limiter, which Analog devices removed from their online tech library several years ago. Morgan was Valley Audio's main designer for nine years. find it here:

Thanks for that. I just printed the matrix circuit and it gave me an idea. But, isn't it actually an M-S encoder? In any case it's interesting how they used the 2015s. I need to print the Morgan docs.

You might check the URL in your last post.

The url works fine for me. It takes you to Google Mail and you have to put in the DIY group user name and passwork. There you will find the complete 430 and model 6 schematics I uploaded.

The matrix is for M/S encoding, but with a little immagination and an IC configured as an inverter, this can magically transform into a M/S decoder. You could even get fancy and stick a "shuffler" in there if you wanted to be historically accurate.

Jim,

We'll need to keep that account a bit under the radar, so I took the liberty of editing your last post a bit..

Thanks Jakob. I will just PM the person next time and be a bit more discreet.
