| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Ramtubes, PEACE! I'm sorry for my comments. It was uncalled for. I have short fuse (electrical term :) ) recently, since I completely lost hearing in the right ear few months ago (replaced by loud white noise - so much for Benchmark's fantastic... | |
| A very good ENGINEERING explanation of why analog can not be as good as digital.. It is not matter of disproving, but rather knowing limitations (understanding it). This theorem only states that you can recover continuous signal by sampling at least two times per period. It does not say you can do that when waveform constantl... | |
| A very good ENGINEERING explanation of why analog can not be as good as digital.. No matter what the resolution and data rate a digital representation of a sound, it will always be an approximation of the original event.+1, Tom1000 | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker I think, we are talking about two different things. I have never mentioned actual amplifier's power at clipping but rather manufacturer's specifications (that are quite different), that calls for power doubling (or close to it). I have also notic... | |
| RMS Power? Al, I was right (he is not going to get it). RMS value of ANY sinusoidal waveform, having peak at 200 (of any unit) is 141 (of the same unit). 100W would be an average power value corresponding to VrmsxIrms and equal to half of peak power for sine... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Yes, drop across resistance will double, but reserves in power supply combined with the feedback will make up for that.I dont see why it is a virtue especially if it is just a spec and not what is really going on. Has Stereophile tested any of the... | |
| RMS Power? From Wikipedia "Audio Power"As described above, the term average power refers to the average value of the instantaneous power waveform over time. As this is typically derived from the root mean square (RMS) of the sine wave voltage,[6] it is often... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Ramtubes, I explained exactly what I agreed with by quoting your statement - read again.Why are you bringing emitter resistors again, yes we know that they exist. I'm not sure why you're asking me what Benchmark voltage regulation is. Perhaps y... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Once an amp clips feedback cannot make up for these losses. I agree, but amp that doubles power exactly has to have adequate power supply AND deep negative feedback. Exact doubling implies perfect regulation (ideal voltage source), that is not po... | |
| A very good ENGINEERING explanation of why analog can not be as good as digital.. Why not bring other issues related to digital, like aliasing or jitter? Also Nyquist/Shannon theorem applies to continuous waves only. Yes, you can accurately recover the sinewave with only two samples per period, but to do so you need a lot of pe... | |
| Help with choosing music server Fast, I had the same problem of dropouts until I changed to 5GHz band (bought dual band router). 2.4GHz has only 3 channels (since each of 12 channels is more than 3 channels wide). 5GHz, in addition of higher number of channels, has advantage o... | |
| Damping Factor The highest effective DF (for the purpose of damping motion of the membrane) is 1.5It is because DF comes from dividing nominal speaker’s impedance by total impedance in the circuit. It is important to understand how damping of membrane works. Whe... | |
| Could I be a Retail Wretch? jetter, sure all is in the intentions, but I also feel that demoing equipment is a part of manufacturer's service thru the dealer in order to promote their product. I cannot imagine car maker authorizing any dealership that doesn't provide test d... | |
| Rectifier Tubes At the top of rectified full wave sinewave current changes direction but rectifier is too slow to respond and keeps conducting in opposite direction for a moment then snaps back to zero current. Fast snapping back creates very narrow negative curr... | |
| Yter cables direction Why would you think it is important if manufacturer doesn't (doesn't mark it)? I could not find anything about directionality on their website. |
