Re: Mid Side M-S Matrix Uses No Precision Resistors

https://proaudiodesignforum.com/images/jpg/1240_Block.jpg How do you sum L and R with equal weights using R3 and R4 with a 1243 when they are unequal values? Why use a 1243 at all? In the original MS in this post when mono signals are input there is 6 dB gain in the L+R stage. To avoid that have a ...

Re: home improvement turns into science fair projects?

The house being two story was the greater challenge. My wife and I are not big stair-climbers anymore. I looked at enclosing the carport which was do-able. Couldn't extend outward since it was near the property line. Based on the comps of our current home and the price of the one we were looking at ...

Re: Mid Side M-S Matrix Uses No Precision Resistors

I don't believe unequal loading of the buffers feeding the input resistors has that much effect on crosstalk from a practical point of view. The closed loop output impedance of the buffers is in the milli-Ohm range which is about an order of magnitude less than the actual resistive mismatch of the l...

I think the pecans we saw were last year's crop.

IIRC the fall crop comes into the stores in early October.

Re: home improvement turns into science fair projects?

Seeing the 45 MPH sign makes me wish I were in a small town like Hickory. Dallas has begun to suck really, really bad. There is mass mental illness here in the form of TDS and covid-hysteria. The speed limit on our wooded country-like street is only 25 MPH but 1 mile in either direction and its Mad ...

Re: Cheap Surround sound buffer/level shifter

I am leaning toward the opa 2156 TI cmos amp, not cheap but for a one off project why skimp? I'm glad that you now get the one-off concept of this and other DIY fora rather than falling into the mass-produced lowest BOM manufacturer mindset. Combining that with analog blinky lights I see a real bre...
