Re: Mid Side M-S Matrix Uses No Precision Resistors
Roger - Nice tight simple layout. I like it! FWIW: The type of resistors that would be needed for external gain trimming that equal the matching accuracy of the balanced line receiver's internal ones would be something like these Vishays: http://www.vishay.com/docs/63001/s.pdf The 1240 line receiver...

OTB Mixer Using Current Summation
This thread has been renamed since it picks up JR's original thread on an OTB mixer using VCAs and current summation. I happen to be the guilty party who mentioned that Pease's article contained info which could potentially solve a VCA bus capacitance issue. The first couple of posts discuss Pease ...

Re: Mid Side M-S Matrix Uses No Precision Resistors
With THAT1646s they are not needed. If someone wanted to use SSM2142s or DRV134s they need to be pre-loaded in 600 ohms to be gain-accurate with active balanced (bridging) inputs. If there's not room for them don't worry about adding them.Oh yeah, do we need termination Rs on both drivers?

Don't forget the french fries cooked in lard, the Jolt Cola (hard to find here) and unfiltered cigarettes. My Dad smoked Lucky Strikes.

Re: Mid Side M-S Matrix Uses No Precision Resistors
Works for me. Then we can link them and when we come up with a trim method they can be inserted.

Re: Mid Side M-S Matrix Uses No Precision Resistors
Yes happy Thanksgiving everyone! Yesterday I had a chance to sketch a few things out with the 0 dB position being a wire to the previous stage. I'd like to find a simple way to provide this trim without the 0 dB gain error. I'm not there yet. Complete bypass of the stage is another option, one being...

Re: Mid Side M-S Matrix Uses No Precision Resistors
Roger - There needs to be some means to bypass this stage to provide accurate gain in addition to the bypass we already have that goes competely around the insert. We need wire between the decoder's line receiver and the matrix. Without that, the 0 dB attenuation setting will not be exactly 0 dB (wi...
