What about a dual mid-side encoder project?

Where we discuss new analog design ideas for Pro Audio and modern spins on vintage ones.

Front/rear flip is maybe the simple way to change front/rear perspective (or correct backwards placement) without adding to the actives.



wow, that Schoeps DMS Splitter Box for Double-M/S is north of $500.......

The encoder, which is a passive design, is about $1400.

Thanks for the block diagram.

I've got to build some boards and will be back on this in a few days.

With the Twin it looks like you need 3 preamps, the breakout and the encoder.
What a mess.

Seems like there should be a three channel FSR mic preamp bolted onto the front for an all-in-one box.
FSR In at Mic level with LR plus RAW Out.
Or just the option for Encoder-Only.

I've been wanting to do a mic preamp using the Zetex transistors for a long time.
How many DIY 3 channel mic preamps are out there?

The only 3 channel preamp I’ve ever seen is an RCA from the 1930’s, back when that covered an announcer and 2 radio studios! Everyone is prejudiced towards even channel counts above 1, so it doesn’t exist that I know of.

A front end pre and an option for line in would give ultimate flexibility.
