Re: Mid Side M-S Matrix Uses No Precision Resistors
Thanks for joining us Brock! I just got the test run with silkscreen and solder mask. Great work Roger! https://www.ka-electronics.com/Images/jpg/MS162_Photo.JPG We rotated the insert connectors 90 degrees. I've dry-fitted the Phoenix connectors to check the mechanicals. After I've built this one we...

Cedar Hill Texas.
The Ranch Steakhouse finally got their website happening. This place is awesome. In fact, we ate there just last night.

Re: NR compander (P-522)
John - I think I have a copy of the scan you sent that I could turn into a pdf for the TS-1.
I also want to re-size your NR image. It may take me a couple of days 'cause there's some stuff goin' on here.
Are you familiar with the NTI line? http://www.nti-audio.com/

Re: NR compander (P-522)
Very nice John! I printed out the schematic so I could follow it along with your text. Elegantly simple. I like what you did in the detector and yes the 570 and the rms seem to be similar in being able to use this trick. The diode limiter for overshoot protection with it's soft-limiting would seem t...

Re: OTB Mixer Using Current Summation
I just found the PAR article "Digital vs. Analog Summing" I promised earlier. I couldn't find it anywhere on their website so here's the scan. It makes a nice case for OTB.

Re: Mid Side M-S Matrix Uses No Precision Resistors
I did crosstalk measurements on MS155. The input was 0 dBu. Left channel 1 kHz, right channel 10 kHz. The 1 kHz crosstalk from L into R is displayed in red. The 10 kHz crosstalk from R into L is in green. This is the precision bypass/monitoring mode. *Points C to F here: http://www.picocompressorfor...

Re: Mid Side M-S Matrix Uses No Precision Resistors
I just finished the new prototype, MS155. This layout has a 5532-based 6dB attenuator on the decoder to compensate for the 2L and 2R de-matrix terms. Thanks to Roger's layout skills it passes signal perfectly. Note that the four added precision resistors are not actually in the matrix - the are in t...

Re: Mid Side M-S Matrix Uses No Precision Resistors
Thanks Paul. Let me ask you something... In the latest spin of this we've added the -6 dB stage in the decoder's output. They are in the L and R domain and compensate for inherent gain build-up produced by the algebraic 2L and 2R decode terms. The MS-155 board is overall unity gain from encoder inpu...

Re: A Discussion About True Power Summing for Stereo Compressors
Here's an application note "The Mathematics of Log-Based Dynamics Processors" that may be useful to our readers. It only touches upon the time constant differences between feed-back and feed-forward and deals primarily with steady-state threshold and ratio. http://www.thatcorp.com/datashts...
