| Volume control vs. attenuation control Everything I said is correct. The problem comes when trying to explain technical terms to non-technical people.. I'll drop it after this because it is clear that most who have contributed are using terms the way non-technical people use them. Ther... | |
| Volume control vs. attenuation control Can someone please explain the difference between a volume control on an amp and an attenuation control on a pre amp. You start with a very small voltage signal from a source like phono cartridge and follow that with a series of amplifiers that ma... | |
| difference from higher input impedence on amp? If they use a standard configuration, using a plug in attenuator is not the same as raising the input impedance of the amp internally. I'm assuming the resistor being talked about is from the input to ground. The plug forms a voltage divider which... | |
| Damn Apple..a fence sitter's dilemma Firewire and USB are both more than fast enough to handle the highest resolution audio currently available. Any additional speed isn't needed. The current high end Firewire and USB DACS sound excellent. If you are ready to make a move do so now. T... | |
| what speakers demand high end electronics ALL speakers require high end electronics to sound their best. All sources require high end preamps to sound their best. All amps require high end speakers to sound their best. All anything requires all high end everything else to sound their best... | |
| Wiring an Isolation Transformer Yes, I did read it. It doesn't say anything that I can find about 120-120 having less isolation, in fact it says "The advantage of operating a Balanced Input or a Balanced Output is noise reduction as a result of the balanced line common mode nois... | |
| Wiring an Isolation Transformer Was it..... Was his mind made up?... Set in concrete?Having a bad day? No need to be snippy. I said "if." I didn't say set in concrete,, I didn't say his mind was made up. BTW I'm still curious how it is less isolated wired as 120-120.. | |
| Wiring an Isolation Transformer Please explain 120V in 120V out will not yield all that much isolation. Better to wire the xfrm 240V in, single ended 120V out.If the purpose of the exercise is to have a balanced secondary then he has no choice but to wire it as stated above. You... | |
| Wiring an Isolation Transformer First of all, if you are not sure how to do this I seriously suggest you enlist the help of someone locally who can help. It is possible to kill yourself or burn your house down if you screw up with electrical work.To run it balanced you'll need t... | |
| Why no heated gear? I live in NY and I have to say that my tubed gear takes the same amount of time to warm up in the summer as the winter.I assume you have some sort of HVAC system in your home that keeps the temperature in your home in a relatively narrow range win... | |
| Why no heated gear? .So i am sort of confused about some saying yeaah, external heat caould do it..I see why you are confused... because nobody ever said that. Nobody ever said that external heat could keep a component at its optimum operating point.The question was,... | |
| Why no heated gear? Do you possibly believe that you can pre-heat a tube to anywhere remotely close to operating temperature?uh, did I ever say that?And regarding your last statement that there is no such thing as heat potential in a tube. Really?Despite referencing ... | |
| Why no heated gear? .The original question waswhy don't manufacturers add heating elements to equipment to bring it too optimal temperature quicker.It is ridiculous to think that externally heating a component won't do just that... "bring it to optimal temperature qu... | |
| Why no heated gear? .Your analogy doesn't hold water. Pouring hot water on your car is a terrible analogy.. A better one would be if you store your car in a heated garage so it is heated all the way through, not just on the surface. In that case it would definitely m... | |
| Why no heated gear? Just so, the external heating of electronic equipment is not really effective.I have a feeling I'm going to regret asking, but what do you base that on? Experience, some research you've read about, or just a guess? So you are saying an electronic ... |
