| TRL Dude or Joule 150 MKII for Major Pre Upgrade I measured the Atlas amp again. It turns out if I touch the back steel plate I get no ohm reading. However when I touch a screw on the back plate with the center power cord ground pin on the iec I get a 14 ohm reading.I learned this from calling A... | |
| Possible impedance matching issue with subwoofer? That is what I thought and thanks Al. | |
| Possible impedance matching issue with subwoofer? Ok, one last question so I can make my final decision. I am not sure I want to go the high level hook up route as I simply don't know how the plate amps are wired. Can't see anything as all the sub binding posts are hooked together on a circuit bo... | |
| Possible impedance matching issue with subwoofer? Ha, ya a BIG hum is the last thing I need1 | |
| Possible impedance matching issue with subwoofer? Al, the builder told me if the plate amp has the negative high level input grounded or in common with another connector (left minus connected to right minus, then I would need to do a special connection from the Atlas. Connect only one phase of ea... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Mine preamp's chassis is indeed grounded to the middle pin of the iec. Again, the buzz comes when the preamp is off and unplugged even. I have an amp issue. I called Aesthetix today and they gave me some other things to measure on the amp. I will ... | |
| Possible impedance matching issue with subwoofer? Thanks Nsgarch and Almarg for your comments and help. | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade I meant to say I measured no ohms. I assume getting no ohms means there's no connection from the signal ground as measured at the RCA socket to chassis. Same with the power cable ground to chassis. The chassis has no resistive connection and seems... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Well the amp seems to be the issue after more testing. I tried using Blue Jean cables that are well shielded, but the buzz continues. Again, with the preamp off and unplugged the buzz continues.I measured as Ralph stated and could not get any read... | |
| Possible impedance matching issue with subwoofer? BTW, my pre to amp ic is only 3 feet long. Yes, I use the LC-1 sub cable. | |
| Possible impedance matching issue with subwoofer? Al, you are the MAN! thanks so much for your help. | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Atmasphere, I will take the measurements you point out and post the results. | |
| Possible impedance matching issue with subwoofer? This Burson buffer may be just the ticket. Thanks for the idea. On paper it sounds good, anything I'm missing here? Seems it allows me to get the best sound out of my subs as well as my main speakers? It costs $320 however and I wonder if just hoo... | |
| Possible impedance matching issue with subwoofer? Al, understand all your comments and thanks. Very interesting stuff here. Quite a lot to know and be aware when adding subs to some systems. Yes, my pre has 3.3uf coupling caps. No, my second output is not buffered separately. I use low capacitanc... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade The Dude is not the issue at all. I have tried three preamps in the system and one of them was a passive. As soon as ANY of these 3 pre's are hooked up by ic's only - the buzz starts. Just an FYI. The preamps don't even have to be plugged into the... |
