  1. Just picked up a RSB-14 and 2 minutes after powering up the sound bar, I hear a constant hum or static sound. Very noticeable when I mute it. I have reset it, tried every input. Changed HDMI cable. Tried a different wall power outlet. Makes no difference. I assume this is not normal and wondering if anyone else has experienced this. I have attached a sound file (.m4a) if interested in hearing it. Any suggestions, besides returning it? Thanks in advance. Klipsch RSB-14 humming (22JUN18).m4a
  2. Hi everyone, I just purchased a Klipsch R-115SW subwoofer. I also have a SVS PB-13 ultra that I've kept right next to the Klipsch for testing. I ran some tests and the Klipsch sounded louder and more punchy, to my surprise. However, after a few tests I noticed the Klipsch was emanating a hum noise. After doing some experimenting here's what I know: 1) When the Klipsch is on and not connected to anything it does not hum 2) When the Klipsch is on and ANY audio connector is connected to it, it will hum, even if the audio connector is not connected to the receiver! 3) If I take the exact same audio connector and plug it into the SVS I have no hum from the SVS. The Klipsch's power plug only has 2 prongs and no ground level. The SVS cord has a ground level. It seems to me that the Klipsch's input ports are overly sensitive or defective. The hum is very loud at max volume and does get quieter as the sub's gain drops. However, the hum only vanishes once the sub's gain is 0. Please help, I really like this sub and I don't know how to fix it! Thanks, Prem
  3. 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
  4. I recently picked up a pair of klipsch R-15PM and I am getting a terrible hum when I switch it to the input to play my record player (Audio-Technica-LP120-USB). I have tried it while using and not using my preamp. I've tried it grounded to the preamp and tried it just grounded to the speakers. The hum is there when nothing is plugged into the input as well (noting hooked into the speakers, but set the input to phono). The hum does get louder when I hook everything back up, the hum gets louder as I increase the volume and makes using my record player to listen to anything impossible. I was wondering if anyone had any suggestions? or if the speakers might just be defective? (I returned my first set, because of the same issue and this new pair is doing the same) They work fine when using bluetooth as an input. There is no noticeable hum and I didn't have this hum issue before getting the Klipsch speakers. I was previously using my preamp and a set of old desktop Bose 2.0 companion speakers (10 or more years old), but they finally died on me. Thanks for any suggestions
  5. 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!
  6. so came across this. A 60hz harmonic line filter. what does it do? filters ac ? how? only allows 60hz to pass thru the filter. basically a giant low frequency sub sub woofer filter in design. does it work? seems to. trannies don't buzz anymore and motorized devices don't squeal at high rpms , so yes it works. this one is a 14 amp times 3 440V capable one...it can do three phase. but easy to adapt to single phase 120 or two 120 phases off of 220/240. main thing to remember is to wire as a sub panel....you will need to add a ground bar and a floating neutral bar. and put it in a box so your cat doesn't get electrocuted. duh...welcome to the new forum...pic wont up load..
