Thanks Doug.
It is useful but what I'm not fond about is the anemic Side being attenuated another 6 dB.
Out of several hundred units sold I've only been asked for it twice.
For those situations its a good work-around.

The MSII however allows both Mid and Side to be offset at the insert with Mid -6dB and Side +6 with the gain correction automatically applied on decode.

I took another look at the MSII. I have a pile of the original MS boards so I didn’t look to closely at this.

The switching options are fantastic. I’ve been trying to cobble together what this does with the original boards for my monitor controller. This takes care of all the options I want. Then there is the tilt and widener to boot. Nice!

Thanks Paul!
The MSII added what people usually did with their original MS boards.
I'm about to place an order for more MSII boards which sell out as fast as I get them.
I've been chronically out of stock on those since introducing them a year ago.

The original board is ideal for simple MS encoding/decoding and Mid/Side monitoring.
I'm not sure I'm going to make any more of the original MS but I may do one optimized for Mid/Side monitoring that will run on a single 9V supply or bipolar 15V.
I've sold several for performance applications to guitarists who desperately need 9V operation.
