Re: A Super-Simple LED Peak Flasher Audio Overload Clipping Indicator Using the TL431
Hey Guys, two things: 1. Seems like TLV431 vs TL431 has a Vref of only 1.25 vs 2.5V. Very confusing eh? 2. Some simulation models "generate" Vref if the Kathode voltage is less than Vref. Strange false behavior! OK, 3. Similar devices (~LT1009) look the same but are not programmable except...

Re: Is solid state relay capacitance bad for audio?
Given what you are trying to do, mechanical relays are probably the only way, and even then you may get noise and crosstalk. A binary tree will give you N+1 selection from N cascaded relays. There are Mux chips but opto or not, there are real limits to V/I linearity, voltage range, resistance and lo...

Re: A Super-Simple LED Peak Flasher Audio Overload Clipping Indicator Using the TL431
LOL! I too am guilty of being unkind on occasions that I was unimpressed. This is a simple positive level detector that you can put outside an existing amp. But for integrated into an amp, there are places in the feedback loop that provide clear indication that the range of the output has been excee...
