| Possible impedance matching issue with subwoofer? Going from my Atlas amp to the sub's high level (binding posts) does not mean the Atlas amp is driving the two subs? Right? The plate amp in the sub still powers the subwoofer and the Atlas amp is simply sending out the signal for the plate amp to... | |
| Possible impedance matching issue with subwoofer? Grannyring, all of the understandings you expressed your OP are correct. Whether or not significant deep bass rolloff or other frequency response anomalies will result from the non-ideal impedance match depends on whether or not the impedances tha... | |
| Preamp out to AVR in? Hi Lynne,Yes, you can. The first time you do that start out with the preamp's volume control turned down low, and while playing a record turn it up to the point where you can use the AVR's volume control at positions that you find reasonable. Ther... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Gentlemen, once again let me emphasize that Grannyring's issue arises even when the preamp's power cord is not plugged into an AC outlet, and when no components are connected other than the preamp, power amp, and speakers. Therefore I don't see ho... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Grannyring, your issue doesn't seem to me to be a ground loop issue, as it occurs even when the preamp is unplugged from the AC outlet (and with no source components connected). Therefore I'm not at all certain that a Jensen transformer would solv... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Tim, sounds like the single-ended preamp has a ground loop problem when working into the balanced amp via an adapter, the loop being broken, as might be expected, when the transformer is used.An adapter-based approach that I suspect would provide ... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Tim (Mitch2), Ralph's comment that pin 3 should be grounded when adapting to an XLR input using a simple RCA-to-XLR adapter is of course correct. I would add that the 23.5K nominal input impedance of your Jensen PI-RX transformers is specified bas... | |
| IGBT Identifying Hi Wolfie,If the markings are visible, one of them will hopefully be the manufacturer's part number, which will probably consist of a string of half a dozen or so (perhaps more) letters and numbers.Just enter that part number into Google, and you'... | |
| higher or lower gauge for 3-6 feet XLR cables? I agree with all of the preceding comments. Both gauges are extreme overkill, and other less predictable factors will determine the sonic effects of the cables.As Stan indicated, narrower gauge wires have higher resistance. Resistance in the signa... | |
| Which is more accurate: digital or vinyl? 01-31-12: Orpheus10In addition, harmonics are always presented as a lower frequency affecting a higher frequency, but never how higher frequencies affect lower frequencies. I'm saying these higher, inaudible frequencies affect lower frequencies. C... | |
| What does it take to have a revealing system? A lot of good comments have been offered above, most of which I agree with. However, I would add that references I have seen in the past to the ability of a system to be "revealing" have often confused the ability of the system to reveal musical d... | |
| Help with amplifier choice Although specs obviously don't tell the whole story, and in particular don't say much about how the amplifier's sonic quality will hold up as its maximum power capability is approached, fwiw:40 watts into each of two non-planar speakers that are 9... | |
| Help with amplifier choice I can't comment on the particular equipment, but I would offer the thought that a key variable is the dynamic range of the music you listen to, i.e., the difference in volume between the loudest notes and the softest notes. For instance, if you li... | |
| Is it save to convert XLR to RCA? Could it be a speaker issue? I know it is passive, but.....I can't envision a way in which a passive speaker could cause the symptoms you have described. But I guess it is conceivable that a problem involving the front end of the amp, or the inter... | |
| Is it save to convert XLR to RCA? All the ic's caused a buzz, but turning off the system and placing them in different positions changed the volume and channel of the buzz. What happens if you don't change the cabling at all, but you turn the amp off, wait a few minutes, and then ... |
