  1. Yes. Yes. No, but it was tested with an extension cord and it still had the hum. Yes. The isolation xfmr seems to have cleaned up all this hum. Short answer, you are probably correct. Long answer, I was trying to do a 3-way active crossover high/mid through passive crossover, mid/low direct connect to woofer speakers, which leaves low to subwoofer. That being said, I started with a game plan but with the hum, I kinda got side tracked and now that I've got the hum gone, I think I'm going to take a step back and set it up as a 2-way, get everything set back up, I still need to tweak and tune, and then enjoy the home theater.
  2. The hum is gone but, cables, equipment are all pulled out, so as I put everything back hopefully it stays away. There were 2 issues, 1st the amps and crossover are about 8 ft away, if I installed the crossover at the receiver no hum if I placed it in the rack hum returned, the isolation transformer was able to remove this issue. 2nd issue is the subwoofer issue, my plan initially was to pull 100hz and below off the center and cross that over to the sub, and sum it with the sub signal. I thought this was possible, but my sub (SVS 20-39 pc Plus, 10 years old) which does not have LFE, just line in / out, and speaker in / out, does not like it, or its not possible, or I'm doing it wrong. I hooked AVR sub out to left line in, and the center 100hz or below to the right. So it seems everthing is going to work, I'm still trying to figure how to send the center speaker "Low" from the crossover to the sub. What is the best way to sum subwoofer signals?
  3. Signal connection, the Onkyo 1008 has two sub outs, I was trying to narrow it down to the Rcvr or the sub. Both sub outs make a hum, so I was wondering what electrically seperates the two sub outs, if anything. I won't be able to get anything done tonight the wife's watching the tube, and she don't like me fartin around when she's watching.
  4. I must have got lucky, that's exactly what I did RCA pre-out on HTR to XLR to EV-DX and no hum. It's not a fancy wire just regular Monoprice stuff. I think I misspoke, there weren't a lot of articles, there were a few articles. Just wanted to set that straight.
  5. I think I figured it out, after snipping pin 1 on the XLR, it made no difference. I pulled all cables and figured I would start putting everything back together one at a time. When running the subwoofer cable, it returned not to mention it scared the crap out of me. Never install a subwoofer cable with the sub on. I tried a second cable and it still returned. I have another sub I need to bring up from the basement and see if that works. Question - with 2 subwoofer outputs is there any difference in their electrical connection.
  6. Hum is gone, after removing audio cables from the back of the Onkyo.
  7. I won't be able to try this till tomorrow, but there are a lot of articles about when going from pre-out RCA to XLR, the results can be a hum. Rane has a whole page, describing ways to fix it, snipping lead 1 wire, isolation xfmr (Ranes version is balance buddy 44 and 22, Jensen transformers). I will try your suggestions above, since that costs nothing. Next, I was going to try snipping the wire and see if that fixes it, (I have a spare one). Thanks.
  8. Most of my source is HDMI uncompressed digital (Blu ray).
  9. Got the crossover hooked up, cables re-run, just wanted to do a quick check make sure everything was correct. Turned on and got that beautiful sounding ground hum. Did a quick search on Klipsch forums and found out this will happen when switching from RCA > XLR. The signal flow is Onkyo 1008 pre-out RCA > to DBX equalizer XLR > to Ashly XR-1001 crossover XLR > Amp XLR > banana plug into speaker. One recommendations was this > http://www.sweetwater.com/store/detail/HumXLR/ I guess install this before the DBX equalizer. I don't mind spending the money if this will fix the problem. Just looking for any thoughts, thank you. edit: I also read snipping lead 1wire at the XLR connection might fix this issue, but might drop signal level also
  10. I was just curious, specially since I would be passing Bluray audio. What I gathered is the cost is extremely high for the signal processor. Its hard too believe Behringer is able to do it so cheap. The ones I looked at on the internet started around $4000. Anyways, thanks, I will revisit processors when I'm ready to upgrade. I appreciate everyones input.
  11. Sorry I didn't see this, yes they do thump a little, one almost always and the other on occasion and only in the bass bins and it's not loud at all, not enough for me to worry at all. Anyway I usually leave them on, at less than 15 watts idle it's not a big deal especially when they are working 6-8 hours a day. Thanks about the thumping, I will see how bad mine is after I get it, some comments stated its noticeable, some stated no thump, but I guess you can remedy it with a cap or a time delay switch without too much effort.
  12. Thanks, I will stay with what I have, (still waiting for all the parts and pieces to show up), and see how it goes and if I decide to tri amp I will probably revisit the processor upgrade. I would like to ask this question again. Why would you go with a unit of a sampling rate of 24 / 48 khz? If I recall correctly both the EV and the Ashly are only 24/48, are there very few 24 /96's or is it not important?
  13. Right now I'm going to use an Ashly XR1001, which is the analog crossover. I looked at (through the internet not in person) the EV dx-38, and the Ashly Protea, and that may be something in the future for me. The problem I see is my lack of knowledge on setting these up. I would be more concerned on screwing the signal way up and not liking my setup. If I did want to try one, at first, I would probably stay cheap and go with the Behringer DCX 2496. Then my concern would be did I go too cheap, and thats why my sound doesn't sound right. I've read a lot of reviews where they set up their analog crossovers by hearing. Are they hard to setup and can you really screw up the sound quality? Also, I might be missing something here because of my lack of knowledge, but why would you go with a unit of a sampling rate of 24 / 48 khz?
  14. In response to Mark1101 on 04-02-2012 12:21 PM : First, I use my system 99% of the time for home theater. I'm using an emotiva XPA-5 for Backs, and Sides, for those it works great, I'm using an XPA-2 for my fronts, it also works great. I am extremely happy with my Emotiva investment and would not change it out. But the center is the speaker I am bi-amping, I only need around 15 watts for tweeter and around 30 watts for midrange and 150 watts for the woofers. Due to yours' and 1504-5 recommendations on page 1 about using amps with gain control. I decided to add an adjustable amp for this bi-amp. My problem was there are not alot of amps rated in the lower wattages, I looked at QSC but the lowest settings were still too high, I looked at Parasound, but not a whole lot of users bi amping with Parasound, after dtel recommended the Crown I did alot of research towards that, there are a quite a few people that have used the Crown for bi amping and seem to recommend it. It seems they like it alot for woofers due to its high damping factor, but there are no complaints about high / mid usage either. My main focus is on bringing out the dialogue. If you have a recommendation for an amplifier for a center bi amp, with a future upgrade to tri amp please let me know. I'm completely open for any suggestions. Thanks for all comments and recommendations.
  15. This is bad news, especially in an active system. If you decide to use the Thumper-75a, you might want to look at the suggestions in the thread. http://community.klipsch.com/forums/p/76910/758898.aspx Dtel, Can you reply about when turning on and off does it pop or thump, this is one reason I passed on Parasound, but I never found any comments about it on the Crown. Till now.
