| Measuring line noise and power conditioners Generally people don't think of frequencies in the audio band (<=20KHz) as EMI, but as line harmonics. 20Khz has a wavelength of 9 miles (15km), so you need a pretty big wire for a good antenna. These EMI toys don't measure harmonics. You need ... | |
| Measuring line noise and power conditioners This keeps being repeated as "factual", when it never has been. The output of a rectifier includes DC and high frequency components. Simple transfer function analysis. The more of those high frequencies you eliminate, the greater the ratio of DC t... | |
| Unbelievable Resonances are distortion, not noise. | |
| Unbelievable This will never get old ...Hello fuses, my old friend.Geoff has come to talk to you again. Because an electron softly creepingInduced a field while he was sleeping. And the direction, that was planted in his brainStill remainsOutside the bounds of... | |
| Unbelievable You are quick with the insults pebble man, but useful information seems to elude you almost as much as you elude self control every time someone mentions digital, and you jump in with scattered laser light. I have to admit though, you aren't a one... | |
| Unbelievable You used to being not too swift? How did you get used to being like that, going through life with that boat anchor around you .. or was it a bag of magic pebbles on the end of a rope? ... or a directional cable. Yup, that's it .... you are burdene... | |
| How important is a Linear Power Supply Versus a Switcyed one? Most of these small audio manufacturers have commensurate small volume. To that end, they are paying quite a bit for components, and an arm and a leg for assembly. What you can build 100,000 of for $10/each, can cost $100(or more)/each, to build 1... | |
| Unbelievable Triggered much Mr. Kait? | |
| Unbelievable Amazing, you can take something that probably cost pennies in other industries (like impregnation varnishes and coatings for magnetics), put an audiophile sticker on it, and charge 10-100X. Love it!Sorry if I already posted this link to the audiop... | |
| Camp designations What about using cable towers so you could have a model train intertwined with your stereo?Inductance? We don't need no stinking inductance. danvignau, people come up with lots of theories in audio .... mainly people who have something to sell, or... | |
| Damping Factor - Interesting article You are confusing damping factor with dynamic headroom. Damping factor is mainly a factor of feedback, especially at bass frequencies. Dynamic range is a factor of supply rail voltage and capacitor size.Given the love of tube amplifiers, saying hi... | |
| Unbelievable The smiley face doesn't make your post any more viable or correct. A speaker just sitting there, unconnected, does not create "sound" of any appreciable level, and I have a feeling it would be almost impossible to detect short of being in super qu... | |
| Unbelievable Noise is the time varying quiescent output in the absence of an input signal and/or independent of the input signal. In speakers, noise, by definition, is essentially 0, unless you are claiming it is picking up seismic vibrations from the floor an... | |
| Go Buy Some Music You Deadbeat Streamers! As noted, today you have to release an album to promote your tour, that is how artists make money. I feel like that has narrowed the artist choices available to us, and also has narrowed the complexity of the music available to us, certainly for m... | |
| How important is a Linear Power Supply Versus a Switcyed one? At almost any power level, a switch mode power supply will be cheaper than a linear power supply, not to mention more efficient and hence cooler. if standby power is important, they can also superior for that (think always on waiting for a remote... |
