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

Paul - Do you suppose that the popularity vinyl released today (that presumably sounds better due to not being over-processed and slammed to the wall to the degree that CDs are) will somehow cause people in the labels to ask if this CD loudness war shoud be stopped? It's a hope of mine. Is it even t...

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

Somehow the Mexican food spread inside ZZ Top's Tres Hombres just wasn't the same in CD format :(

I've been planning a trip to Best Buy to see what they have on LP now. I have a mental image of the new Foo Fighters LP spinning on the turntable.

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

BTW an intersting factoid that you guys may already be aware of. My daughter is in management at Best Buy. She told me that for a couple of years now vinyl is outselling CDs both in units and dollars. I mentioned to Paul in an e-mail that when I moved the first thing I hooked up - before the DVD pla...

Re: Mid Side M-S Matrix Construction Information

Very nice build! Thank you for sharing the pics. The goal I had for this project was transparency to the degree where you could listen through the matrix with the inserts normaled and it would sound the same as the source. I guess the idea I had that day while bike-riding panned out. We all owe Roge...

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

Paul - Your build is awesome. You may hold the record for a rotary switch with the most poles.

Re: Mid Side M-S Matrix Construction Information

I agree that the temp is too low. Have the same problem desoldering leaded radial caps on computer motherboards where the power planes are large and sometimes internal. It's a big heatsink for the iron. I think my Weller's tips are 700 degree (PTA-7?) and I didn't have a problem getting it hot enoug...

Re: Residential Lighting with LEDs: Retrofitting the Pink Ra

A quick update 6/28/11. As I mentioned earlier, four of the 40W Sylvania snow cones just aren't bright enough. Today while shopping at Lowes I found the Utilitech (Feit Electric) LA19DIM/800/LED which is a 60W 800 lumen 3000K. I'm impressed. These babies dim very well, are bright, and don't have an ...

Re: THAT1570/5171 DIP Adapter

The two jumper arrangement looks right to me. Going back to the noise performance I seem to recall the numbers 34 uV, 12 uV and 8 uV for the 1606, "Cohen" symmetrical 1286 (flipped input dual diff amp), and "Birt" NJM2114 with -5.6 dB gain. I think the measurement BW was 100 kHz....

Re: THAT1570/5171 DIP Adapter

IIRC on the original proto demo board the 1606 compared to Birt using a 5532/NJM2114 was at least 10-15 dB noisier. Enough to justify re-doing the board. If you don't care about maintaining output level no matter how the dumbass customers plug in, I still recommend the simpler and more symmetrical 2...
