| Heat heat and more heat?? Dave, based on the info in the manual that I referred to earlier, about XLR pin 2 being shorted to ground when the RCA inputs are selected, I suspect that the only thing that switch does is to put that specific short in place when the RCAs are sel... | |
| Heat heat and more heat?? Good! The 100 ohm figure is easily high enough, regardless of what the number is in the amp, to make it unlikely that the sub connection damaged the amp. That resistance would have limited the current through the roundabout path I described earlie... | |
| Looking for really fine cables at really low price 09-05-15: MikirobIt is astounding to me that the about $15,000 Tara Labs speaker cable can be compared to the about $80 WE16ga speaker cable in the same breath, with the WE16ga comparing so close, so favorably, to most if not all the vaunted speak... | |
| Heat heat and more heat?? Dave, if you happen to have a multimeter there are some measurements you could make that might provide insight into whether the overheating problem has resulted from the sub connection issue. You would disconnect the sub and the amp from each othe... | |
| Heat heat and more heat?? 09-05-15: DaveyfAl, one more question...could I connect the ground wire from the sub to my preamp, with the other two connections going to the amp? The preamp has a ground connector for a turntable, which I use for that purpose; could I hook up th... | |
| Heat heat and more heat?? Dave, rather than using an adapter you might also consider simply purchasing a 3-pin male XLR connector and wiring the one connection (black wire to pin 1) yourself. For one thing, that would undoubtedly be a good deal less expensive than using a ... | |
| Heat heat and more heat?? Correction to my previous post. When I said:That and most such XLR-to-RCA adapters will connect the RCA ground sleeve to XLR pin 3 as well as to pin 1, but I'm pretty certain that won't matter in this case.... upon looking at the manual for the 8T... | |
| Heat heat and more heat?? You're welcome! Pin 1 on the XLR connectors would also be a circuit ground point. Perhaps a convenient means of making use of that would be to obtain an XLR-to-RCA adapter, such as this one, inserting it into one of the unused XLR inputs, connecti... | |
| Heat heat and more heat?? Ideally the black wire from the sub should be connected to a circuit ground point on the amp, but it appears that the Rowland 8 does not provide a binding post or other terminal corresponding to its circuit ground. (There are some balanced amps, s... | |
| Magnet Wire Question This is one of the very rare occasions on which I must disagree somewhat with my learned A'gon colleague Kijanki.Theoretical skin effect in copper at 20kHz starts at gauge 18.16 and 14 gauge will therefore experience a very slight rise in resistan... | |
| Heat heat and more heat?? I believe that your Rowland amp is fully balanced, and it appears that you may have a REL sub in the system which uses that amp. If so, are you connecting the sub at speaker level, and if so are you making the mistake (that is not uncommon when co... | |
| Hear sibilance on Krall, Famous Blue, D. Fagen? Rebbi, I don't have any of those recordings, but based on what Jim and Bill have said I would expect that the major contributor to the problem is the system rather than the recordings. Given that, and given that "jitter" (high frequency random or ... | |
| Magnet Wire Question I couldn't find an impedance curve on the CP6311, but I suspect that its impedance in the top octave either rises to relatively high values, or at least doesn't decrease significantly below the nominal 8 ohm spec. So inductance is probably not all... | |
| Prilaluna Prologue Premium with KEF LS50 If you are presently using the amp's 8 ohm taps, given the upper mid-range impedance peak of the speaker, as shown here, going to the 4 ohms taps will probably reduce the peakiness of the upper midrange. Although it may also have other sonic effec... | |
| wattage 77jovian, the main reason that SPL decreases as distance increases, in a reasonable home listening environment at least, is not related to atmospheric attenuation. It is the result of the sonic energy "spreading out" over a progressively larger cr... |
