| ATMA SPHERE SCHEMATIC for a UV-1 M/M....... As usual, Ralph is the epitome of class and helpfulness.Unfortunately the same can’t be said for some others around here.Best regards,-- Al | |
| Hum coming from Left and Right channel - RCA to XLR Adapter No, that would not be a good idea in this particular case.Most XLR-to-RCA adapters short the signal on XLR pin 3 to ground (XLR pin 1). While that is appropriate when adapting to an XLR input, and is also often appropriate when adapting XLR output... | |
| ATMA SPHERE SCHEMATIC for a UV-1 M/M....... It seems to me that: 1)Ralph has provided as much information as he can, within the bounds of practicality and reasonableness. 2)What he has provided is a lot more than what most manufacturers would have provided. 3)What he has provided is all o... | |
| Preamp & Subwoofer impedance mismatch? I believe that I heard that JL has new subs with higher input impedance to address this issue. Good point, but looking at the JL website it appears to apply to the Fathom v2 series (those models having unbalanced input impedances of 50K, although... | |
| Preamp & Subwoofer impedance mismatch? While the 10K load would certainly not be an ideal match for the preamp, a mitigating factor is that the **variation** in output impedance between 20 Hz and higher frequencies is not huge. In many other tube-based preamp designs the output impedan... | |
| Why do my new Transparent cables make my system sound muffled? Given that the 12k input impedance may be an issue, and that the ratio of the output impedance of the pre-amp and input impedance of the amp has some importance (from what I’ve read), maybe the Rotel pre-amp might make a difference? If my guess is... | |
| Why do my new Transparent cables make my system sound muffled? P.S: If the guess I provided in my previous post is correct, a solution might be to simply connect the cables to the amp’s XLR inputs via RCA-to-XLR adapters. That would probably result in the cable working into a 50K impedance (half of the balanc... | |
| Why do my new Transparent cables make my system sound muffled? I presume the Transparent cables have RCA connectors, since the SR8500 does not appear to provide balanced inputs or outputs. And I see that the Rotel amp has a very low unbalanced input impedance of 12K (while having a much higher balanced input ... | |
| Can I hook up a DCS Puccini player/preamplifier directly to an ARC GS150 ampilifier? After looking at the descriptions and specs of the two components I see no reason why they wouldn't work together properly, without a preamplifier. I can't comment, though, on whether inserting any specific preamp into the chain would be likely ... | |
| Effect Ohms Have on db and Speaker Sensitivity There are a many possible causes of the symptoms you have described that are more likely to be responsible for the issue than the fact that the speakers have a 6 ohm nominal impedance instead of an 8 ohm nominal impedance. One such factor being ho... | |
| exceptional voices of female singers (non-classical) It would help if I read MORE carefully before posting an emotional response! Tablejockey, FWIW there were others who have also posted in the thread expressing surprise that a particular artist had not been mentioned earlier in the thread, when in ... | |
| Effect Ohms Have on db and Speaker Sensitivity As Kosst alluded to the question is somewhat unclear. But **if** you are asking what the difference in SPL would be on a per watt basis between an 8 ohm speaker rated at 97 db/2.83 volts/1 meter and a 6 ohm speaker rated at 97 db/2.83 volts/1 mete... | |
| Tekton Double Impacts P.S: I realized after the editing window closed on my post just above that Laaudionut’s amplifier is the XA60.8, while the last paragraph of my post referred to the XA60.5. However the gain, sensitivity, and maximum power specs of the two amplifie... | |
| Tekton Double Impacts First, kudos to Dave (Dlcockrum) for what IMO is an astute, perceptive, thorough, and exceptionally well written review he provided yesterday of his experience with David_Ten’s excellent system. And likewise with respect to the similarly well writ... | |
| Biamping with very different amps Hi George,The KUBE would allow the gains of the two amps to be matched without using a separate passive volume control. See section 3.6 of the following document:http://www.kef.com/uploads/files/en/museum_pdf/90s/Reference_Series_Model_107_2_Ins... |
