| CAN I RUN 50HZ AMP ON 60HZ? There's a problem with overheating using 60 hz power supples on 50 hz power since the effect would be an overvoltage, but not the other way around. Also, running at 60 hz increases the ability of the transformer to accommodate a larger voltage swi... | |
| Air conditioning a home theater. The slim units are notoriously expensive to repair and the indoor unit should not be more than 25 feet from the outdoor unit so as not to burn out the compressor. They are more efficient than an in-window unit but start out at 12,000 btu and above... | |
| Maximum Theoretical Speaker Efficiency Speakers are typically 5 to 10 percent efficient. You can never get 100 percent of the electrical energy into sound because the driver cone to air impedance coupling is so mismatched that it cannot be a perfect "transformer". But the other factors... | |
| Mixed Results from My Hifi It's not equipment or room that's the primary problem, IMO, it's the recording. Your classical and jazz cd's that sound great are probably recorded with 15 dB or more of headroom while the pop/rock stuff is probably recorded with only 3 dB of head... | |
| New to tubes have questions The biggest "don't" is never power on a tube amp unless it is connected to a speaker. | |
| Help I think my AC is polluted "Dirty AC" will not cause transformers to hum, but direct current in the AC line will (transformers are AC devices). It sounds like you're getting excessive DC in your house on those days. You can complain to the power company or you can buy DC bl... | |
| Why is my amp requiring as much volume gain? The Bryston amp has an input sensitivity switch that selects 1v or 2v input voltage. Check with the owners' manual or Bryston to see if you're using the correct setting. | |
| Yet another Grounding Question-Separate 'Earth' I strongly suggest you check with the local building department or electrical inspector before you let this electrician do any work. The subpanel is not a separate electrical source since it is in the same building as the service. Therefore it mus... | |
| Anyone ever try ear candles for better listening? Pardon my ignorance, but I thought that wax had to be melted before it can be drawn up through the wick. Why not just go to a drug store and buy the Murine kit. It's not as new-age as sticking a lit candle in your rear (umm...ear) but it works nev... | |
| panels vs cones which is best and why ? All speaker designs have pros and cons. If panels had no negatives, so to speak, then that type of speaker will be in demand and the market will dump the other designs to sell what everybody wants to buy.The choice usually falls to what you are lo... | |
| neutrality & transparency: what's the difference ? I would argue the other way. Use photography as an analogy. If you enlarge a photo and the color balance of the enlargement is identical, then the process is neutral. That is, no colors are highlighted or muted (a stereo system is basically a sign... | |
| Need help to trouble shoot the noisy amp. If you cannot identify a problem, you cannot fix it. Please leave it alone. Power supplies are dangerous even with the unit disconnected (those big capacitors can pack a lethal punch). | |
| Amps, Cables and Current: A Question That 65-amp currennt delivery is misleading. You wall outlets are supposed to deliver 20-amps. If you short it out with a piece of copper, you could get as much as 10,000 amps short-circuit current. The 65-amp "peak current" is the same thing - wh... | |
| Humidity question - please try to answer... Humidity does go up when it rains... as for why it sounds better:As the humidity increases, speed of sound increases and sound power attenuation (by absorption) decreases. All because air density decreases as the relative humidity increases. This ... | |
| Isolation Theory Question When you say "... I seem to prefer", you said everything. As for looking to vibration theory for guidance, I have yet to see any vibration mfr, reviewer or dealer put forth a reason for why one strategy is better than others and back it up by appl... |
