| UPS & Small Claims Court? How do we know that you didn't remove the contents from the box and stomp all over it? See my point, that's what you'll have to show in small claims court... | |
| need help with impedance on SF power 2 The tap is set for 8-ohms at the factory. I think you have to remove the rear panel to access the tap to change it to 4-ohms to match your speaker. From what I've heard, operating the SF Power 1,2 and 3 at 8-ohms with any speaker is not a problem ... | |
| Advis for a pre with 600 ohms output ? A 600 ohm preamp can drive practically any amp on the planet. Buy what you like based on what you can afford. The input impedance of a commercial power amp is a non-factor - no matter what the value - as far as "matching" is concerned. | |
| Preamp is an amplifier too, right??? Preamps do not increase power, only voltage. A preamp drives a load of thousands of ohms, which is far larger than its own output impedance, and that, along with a smaller power supply, decreases the power produced and transferred. Instead, it inc... | |
| What causes phase shifts...Sean? Other than electrical elements which inherently cause phase shift (and enables passive x'overs to work), there are: room reflections and delays to waveforms introduced by A/D and D/A converters, microphone placement, wiring losses, RF/EMI, process... | |
| Wire twisting polarity. I don't think it matters - each successive twist has the opposite field polarity of the previous. And, no, the hemisphere has no effect. Coriolis "force" mainly affects air mass and water dynamics. | |
| Sound of digital jitter and error correction? Listen to the same recording on both vinyl and digital. Pay particular attention to cymbals as they fade away. You'll see the difference very quickly - the "hash" sound of the digital cymbal just before it fades to quiet is courtesy of jitter. Wit... | |
| power interuption, what to do?? You are basically going to need a 2400 VA single-branch circuit ups system with a battery bank, inverter/charger, wiring and control. The inverter should be a full sine wave type with a built-in transfer switch. This is for one 20-amp circuit only... | |
| High end PCs,,,,,in the wall or power conditioner? Two 600 watt mono's into ONE power conditioner? No way. Current draw will be constricted regardless of where you plug it in (20 amp, 30 amp...). A pair of P1200's may even be a little shy, and they cost a lot more than a few extra feet of power co... | |
| Can you warm up your tube amp ... Some tube amps can be on without a speaker load (as long as it's low power) and some will short out at dc right away. With any tube amp (especially the 100 watt ARC's) it's best not to take any chances. Use an old pair of speakers or a dummy power... | |
| ++++StereoPhile Class A components+++++ Once upon a time, Stereophile reviewed the Wilson Witt speaker, gave it a "high" Class B rating. Wilson reacted like a little girl, personally set up the speakers at the editor's room, and lo and behold, they were reconsidered as Class A. That did... | |
| What is a switching power supply for amps and A switched power supply generates high frequency noise - lots of it. That's the major disadvantage. The advantage over a linear supply is that the overall size is much smaller, requires only a 5 volt starting power at the switch (instead of a line... | |
| The truth about interconnects - can you handle it? As we go trolling along... My "truth" is based on what I hear, not what I read with respect to audio products - especially other people's pre-conceived prejudices. Yeah, I can handle it. | |
| Measuring AC phase Question Remove the neutral wire from the outlet and measure the voltage from the nuetral to ground. If this is 10 volts, then you have either a high resistance in the neutral, poor utility neutral connection, or the neutral is not grounded properly at the... | |
| Measuring AC phase Question I wouldn't rewire the outlet. If you're really intent on reversing the AC polarity, buy a power cord which you can access the plug wiring. Reverse the wires in the plug, instead. This way you won't need a cheater plug nor to shave down the oversiz... |
