  1. Hi, all. It has been a while since I have been on our forum. I have a vintage quad system using LaScala’s for front channels and Heresy’s (not sure model, so posted what I saw on back of speakers) from 1989 as rears. They sound great, but today when I was troubleshooting another issue (which was user error in that I had not changed the the input on dbx 200x boxes) I detected a slight buzz in both rear channels when I put my ear to the front of the speakers. Not noticeable with music playing, but troublesome to ponder. I thought it my be my sub from HT system (separate setup), but I unplugged it and still have issue. It is in both speakers, but not in front channels. I do not crank these and the rears are usually less loud than the fronts. Any idea what is going on? Thanks for any help or advice! I like to take care of things, so hope to figure out the issue. I love my klipsches, by the way, so hopefully on this forum people appreciate these speakers and don’t disparage them (it appears not everyone is a fan- too bad for them). My vintage system is comprised of Sansui 9001 receiver, Q8 player, 2 dbx 200x switcher box things, 2 dbx SNRp1’s, and technics demodulator. Thanks again for any insight. Laura
  2. I've got an old SW-12 that I've had out of service for many years. I'm trying to get it to function properly again. I plug it in and I hear a humming or buzzing sound. It could be a 60HZ sound but the plug that comes with the sub does not have the third ground plug. It is simply a two pronged plug. I hear the noise whenever power is going into the unit. It does not matter if there are any connections made or not. I hear the same noise with it connected to the LFE RCA on the AMP. I hear it when there is nothing connected. The volume of the noise is always the same level whether or not the volume on the sub is all the way up or all the way down or if the volume on the amp is muted or high. When you pass a LFE signal to the sub, it still makes the humm but otherwise functions properly. I get LFE frequencies that sound reasonable and all of the control knobs on the Sub appear to function properly. Is there anything that I can do to "fix" this noise other than taking it to a repair shop? What might be causing this noise? If necessary, I could mic the sub and record it and post a .wav file here.
  3. I have the KA-1000-THX Amp that just started to buzz, even with the input disconnected. The buzz is not too loud, so I am thinking a capacitor went bad somewhere in the unit. The buzz gets louder when the THX switch is turned off. I open the unit, disconnected the preamp connector from the main amp board, and the buzz stopped, so it looks like either the preamp or the power supply is creating the buzz. Any thoughts? Are schematics available? Are parts available?
  4. Hey forum! I could use a little help trying to solve a problem I recently got with my ProMedia 2.1 desktop speakers. I've had these speakers for about 8 years now and they've been great. However, a few weeks ago I decided to move my desk to the other side of my room, and when I hooked up my speakers, I heard this loud constant hum coming from my left speaker, even with the volume all the way down (not a crackle but a steady hum). At one point, it got so loud that I could smell the speaker burning, so I unplugged the 3.5mm cable from the back of the speaker and left it alone. A couple days ago, I decided to look more closely, and I noticed that when I plug in the black and red wires into the Left Satellite +/- output, there was a bright spark and the hum returned. I tried swapping wires and speakers, and it's definitely the Left Satellite +/- only. I couldn't notice anything wrong from the outside, and I checked the fuse accessible from the outside as well as the two fuses on the inside, and they look fine. I also looked around in the inside to see if I could see any loose wires or burnt pieces, and everything looked good. I tried moving my speakers back to the outlet on the other side of the room that it was on previously and it still occurs. I would really love to continue using these speakers so it would be great if I could fix this. Thank you so much!
  5. Hi fellow Klipsch fans! Long time since I have visited. I have been enjoying my KHorns without even feeling the need to tweak or change anything! I know, hard to believe Until today, when I heard this faint buzz / distortion. I couldn't tell if it was mechanical or signal. So I started basic signal flow t-shooting, and found my right K-55 to blame. So now what... Well I start to take apart the k-55 using the instructions found here . All looked normal at first. Reassembled hoping that whatever it was had been resolved . Still there. So I take it apart again. This time I look close at the voice coil, and I see that it is a bit of fuzz on it. Distilled water and a cue tip clean it up no problem. Reassembled, and the buzz is gone. Some pretty simple maintenance took care of it. Just wanted to through this on the forum in case anyone comes looking for a k-55- buzz like I had. While I was in there, I also trimmed the red gasket so the excess did not impede the throat of the horn. Well, back to enjoying my Klipschorns!!! TG
