DarkWolf Posted February 6, 2002 Share Posted February 6, 2002 That just about says it... When I turn them on (My KPM 4.1) after they have been off for a while (I use one of the switches on my power grid.) They are perfect, silent and perfect. After a few minutes of music, I can hear a high pitcxh noise... Can't quite explain it. It's not too loud, but it sure does get to me after a while. It doesn't make any difference what the volume is or weather or not the mute button is on or off... It is mostly coming through on the tweaters, but as it gets a little louder over time, I can tell it comes through on the midrange drivers too, if I get close and take the covers off. If I touch one of the drivers, it stops and it kind of sounds and feels like static electrcity build up in that way, but i don't think it is. I don't know what to make of it, I don't think i heard it untill I put these nice new cables in, which I like very much BTW. The sound also seems to fit right in with the upper range of the noise coming out of my computer, so it may be some sort of interfearance.. But then why it take a little while to set in? I've also tried removing the neon lights from my room and that doesn't work either... I kind of think it has to do with the amp warmming up, but then muting it should stop it and the amp doesn't get too hot anyway.. I also tried unplugging them from the computer. No change. Perhaps I need to shield the new cables I got? they are unshielded.. How would I do that? Thanks for any help, I know this is weird. ------------------ I wish I had a space ship.

justin_tx_16 Posted February 6, 2002 Share Posted February 6, 2002 so if you touch the tweeter, the sound goes away for a while? does sound like some sort of static. this is a first, but that probably means it comes from your modding of the system shielding the wires... did the original wires have shielding, or just a plastic cover? don't know how you could do this besides getting some heat shrink tubing from radio shack and shrinking it on the wires btw, do not use a powerstrip to turnoff your promedia's, that has caused some to never turn back on! ------------------ -justin I am an amateur, if it is professional; ProMedia help you want email Amy or call her @ 1-888-554-5665 or for an RA# 1-888-554-5665 Klipsch Home Audio help you want, email support@klipsch.com or call @ 1-800-KLIPSCH RA# Fax Number=317-860-9140 / Parts Department Fax Number=317-860-9150 ProMedia 5.1 Placement Help s> Quote Link to comment Share on other sites More sharing options...
DarkWolf Posted February 6, 2002 Author Share Posted February 6, 2002 Now this is pretty rich... I Think I have narowed down the cause of the problem to not be my speakers (thank god for that!) but the electrical wiring in my house! (D'oh!) I don't know why this would have sudenly become a problem within the last two weeks, your guess is about as good as mine. However, in desperation, I tried out my old speakers. While not having any tweaters to cut my brain in half with like these do, they did fall subjuct to an awful lot of white noise, regaurdless of the volume. I took them down stairs into the TV room, which has the newest wring in the house and they had the same problem. I had also tried this funky Monster Power Strip that we got for the new cable modem after the ld one got fubar'd in a lightning storm. It says it's suposed to clean up AC power... but it didn't do anything. I tried it in the TV room as well with no effect. I also tried using the old wire on one of the stalites and it didn't really make a difference to the bad noise, so I know it's nothing I did. Hehe... me, being me, I now find this noise much more talorable, knowing that it is not in fact the speakers, but the shaddy electric wiring in my house. Not to say that is likely any good for my speakers, but I don' think it'll hurt 'em either. As for using the power grid to turn them on and off.. Well, if that hurts them than that's just pretty damn weak. It's a good grid, so I'm not too scared. Hehe, at least now, the temptation to try to water cool my amp is all but gone! ------------------ I wish I had a space ship.

DarkWolf Posted February 7, 2002 Author Share Posted February 7, 2002 What kind of a deivse is this? I have already tried using a Monster power grid thing that prommises to clean up the AC signal, but it did nothing. I guess I'll take a look at radio shack. How does this thing work? ------------------ I wish I had a space ship. Quote Link to comment Share on other sites More sharing options...
DarkWolf Posted February 9, 2002 Author Share Posted February 9, 2002 Uh, hello? Bump. I would like to know a little more about this EMI/RFI filter thing. I don't mena to be a pain, but I'm going to a computer show today. (Sat. 2/9) and I don't think I'll be hitting Radio shack and I wonder if there is anything else I should keep my eyes out for. ------------------ I wish I had a space ship.

justin_tx_16 Posted February 10, 2002 Share Posted February 10, 2002 sorry, i am out of the office... er i mean my house... LoL! so it is not as easy to get on the net. but ihave some free time rightnow, i am in chicago! muhahahah radio shack, lowes, and any home theator store sells EMI/RFI filters. but monster cable ones are quite expensive. i got one from radio shack and it fixed it for me. the look like surge protecters but have EMI/RFI stamped on them, they must say EMI on them or else they are not filtering the power. ------------------ -justin I am an amateur, if it is professional; ProMedia help you want email Amy or call her @ 1-888-554-5665 or for an RA# 1-888-554-5665 Klipsch Home Audio help you want, email support@klipsch.com or call @ 1-800-KLIPSCH RA# Fax Number=317-860-9140 / Parts Department Fax Number=317-860-9150 ProMedia 5.1 Placement Help s> Quote Link to comment Share on other sites More sharing options...
DarkWolf Posted February 10, 2002 Author Share Posted February 10, 2002 well, like i said i tried an expensive Monster Power strip boasting "lean power cicuitry"... but it didn't do anything... didn't say anything about EMI or RFI though. you are sure you had the same kind of problem? ------------------ I wish I had a space ship.

justin_tx_16 Posted February 10, 2002 Share Posted February 10, 2002 i am positive i had this problem. like i said, it has to say EMI filter on the power strip. monster cable power strips with EMI filters cost at least $69. ------------------ -justin I am an amateur, if it is professional; ProMedia help you want email Amy or call her @ 1-888-554-5665 or for an RA# 1-888-554-5665 Klipsch Home Audio help you want, email support@klipsch.com or call @ 1-800-KLIPSCH RA# Fax Number=317-860-9140 / Parts Department Fax Number=317-860-9150 ProMedia 5.1 Placement Help s> Quote Link to comment Share on other sites More sharing options...
DarkWolf Posted February 11, 2002 Author Share Posted February 11, 2002 Yup, this one cost around $80. It had protection for TV (or in my case, modem) cable as well. Oh well, when I get some more money I'll pikc ne up and try it out. If it doesn't work I can return it. However, I spent all my money on a new hard drive on Saturday. For $213 including tax, I got a Western Digital 120 GB 7200 RPM drive. It's pretty nice. Much bigger than my old 20 gig! ------------------ I wish I had a space ship.
