Matrix vs Discrete

Hey Chuckie: I'd like to see Involve produce a stand-alone adjustable pre-synth unit for us SM owners to use with our SM1, 2 & 3's. What say you? John R

Hmmmmm

Hmmmmm

Here's hoping that means "Hmmmmm - that's an idea worth considering" - rather than " Hmmmmm - are you kidding me?".

Anyone have any equations for pre-processing stereo for the SM for deriving surround sound from stereo?

In the simplest of description:: take stereo left ch, invert phase & mix with stereo right ch at -7.7 dB
Take the stereo right ch, invert phase and mix with left ch -7.7 dB.

Here is how I did it with hardware:

Hardware implementation can be much simpler than that. @par4ken has posted a simple circuit to do this.

Here is how I currently do it today, by software. Much more control & much simpler than to do a full upmix:

If I can confuse you any further, just let me know...
