c12,14.16 gone. Metering will be done post unbalancing right before the 5k mixing resistors. Going with attiny84 somethings on each channel card, 10 leds, will try to emulate an lm3916 with the mcu. low current leds and peak metering should not be too much of a current draw. (led color render is me...

What about the tempco? heat them with a hot air gun and report back.

Hello AnalogJoe I have an APIB USB ADAPTER that drives the System One. System Two & Cascade under ApWin 2.24 that runs OS from XP, Vista, Win7, Win8 & Win10. My next batch is due from my assy. house 31 Aug. I should have some overages after filling my back orders in Sept. http://www.sound-l...

The problem with using an AP SYS1 is connecting it, and running it, in a modern computing environment. Duke (Audio1Man) has addressed the connectivity issues but the last time I looked into it the OS to run Win AP had to be Win 98. I may be mistaken about that and hopefully Duke will visit this thr...

After looking around for a long time I’ve decided on the Analog Discovery 2 along with a Native Instruments Konnect 2 with the Pete Milett interface box. Using the Waveforms software for both. The AD2 has high bandwidth but is only 14 bit. For low noise measurements I’d switch over to the audio int...

#16 quarantine will be over sometime in 2021

The $39.95 price tag does seem quite attractive. Another option that people seem to love is REW, I dont know, I always felt like it was sub-par, may have something to do with the fact that REW was initially a tool for audio enthusiasts to measure their room response and later it was upgraded to a fu...

BTW I've never liked the Quantasylum. Lots of reports of bugs and it doesn't do swept sine response measurements. Sometimes you just want to generate a tone... https://quantasylum.com/collections/frontpage/products/qa401-audio-analyzer AFAIK the latest updates from QuantAsylum allow the QA401 to ma...

Wayne, that looks like a nice EQ. AFAIK, there is no such thing as a first order elliptic filter, meaning that the polynomials in the transfer function are never below 2nd degree in order to be an elliptic filter, however I think you are refering to the final roll off which can be 6dB per octave wh...
