| BNC or Coax? So, is the concensus that RCA termination or BNC termination is equally reliable for transmission of digital audio (say between transport and DAC)??? Or are there quantifiable differences between the two type of connectors?I don't think it's readi... | |
| Measuring A Capacitor Most problems of this type are not caused by pickup of electromagnetic fields through the air, which would be potentially helped by shielding (if it is properly grounded). They are more often caused by differing ground potentials between the chass... | |
| On one leg or two legs? Jim -- He appears to have answered that, at the end of his first post dated today.-- Al | |
| On one leg or two legs? That's very interesting. So the amp with the more severe hum/buzz also has lower gain. It could be due to a lot of things, but I suppose the most likely culprit would be a tube. Perhaps before taking it back to him it would be worthwhile switching... | |
| Measuring A Capacitor It says that the problem is not the preamp! It is outputting hum because hum is going into it. There are many threads at Audiogon on phono hum problems that you can search through. A few possible causes that come to mind:-- Your power amplifier is... | |
| BNC or Coax? Here is more information on the SPDIF protocol, which as Ghostrider45 indicates can be transmitted over coaxial cable that can be terminated with either RCA or BNC connectors (and can also be transmitted over optical cable):http://en.wikipedia.org... | |
| Measuring A Capacitor I can't imagine a scenario where shorting an input would cause noise on the output but I suppose it won't hurt to turn it off first.Here's one possible scenario: As he is inserting the foil or whatever he uses to create the short, it comes into co... | |
| Opposite effect with cardas/Ayre CD I took a look at the writeup on this cd at the Music Direct site. I strongly suspect its main effects (perhaps its only effects) would have been on the flexibility of your speaker drivers. That will in time return to where it was, although it's ha... | |
| BNC or Coax? I have heard that BNC beats coax for video Once again, BNC is a connector, and coax is a cable, so your question is unanswerable. Assuming you mean to ask whether a BNC connector is better to use for both video and digital audio than an RCA connec... | |
| Measuring A Capacitor Yes!-- Al | |
| Measuring A Capacitor Do I need to turn anything off while I'm doing this?Yes, definitely, although it might be less critical if a different input were selected while you applied or removed the short. But that would be bad practice anyway. If a component like that is ... | |
| BNC or Coax? I suspect that you meant to ask whether a BNC connector or an RCA connector is preferred. The answer would be the BNC connector -- it is designed to handle high frequencies, and will provide a better impedance match to the cable (which is importan... | |
| On one leg or two legs? Maril -- Do try what I suggested with a battery-powered portable AM radio, checking to see how much interference or buzz it picks up in the room, and if it is significant, walking around with the radio to try to track down its source.How close are... | |
| Audiophile quality variacs to decrease voltage? Excellent suggestion by Microstrip. Just to make sure it's clear to everyone, the primary would be connected across the ac line, in addition to the secondary being connected in series between the hot side of the ac line and the hot side of the out... | |
| On one leg or two legs? Maril,Yes, based on the facts indicated in your last post, I feel pretty confident that is what is happening -- the BAT's, with their 200kHz bandwidth, are picking up interference through the air.The source of the interference is probably somethin... |
