mtber101 Posted December 6, 2005 Share Posted December 6, 2005 The only speakers from klipsch that i've had other than my new 75's are the promedia stuff. They always had a hiss to them and klipsch said it was because of the gain being turned up on them. However I just wondering if a hiss is normal on the 75's? The only time the hiss goes away is if the receiver has been muted. Any thoughts? Could it be my receiver? Quote Link to comment Share on other sites More sharing options...
Speedball Posted December 6, 2005 Share Posted December 6, 2005 I had a hiss the other due to the disc that was playing. I would say it is your source, not the speakers that is causing the hiss.....cd, tuner, tape deck, amp..etc...etc. Quote Link to comment Share on other sites More sharing options...
cjgeraci Posted December 6, 2005 Share Posted December 6, 2005 Welcome to the world of revealing speakers. What you are most likely hearing is the noise floor for your particular receiver, which contains both a processor and amps inside the unit. Some processors and/or amps are noisier than others at idle (no sources playing) when the units are on. Even some of the more expensive preamps and/or amps I have run have not been completely and deadly silent at idle; there is usually some hiss or noise at idle. Since horns are revealing, you will hear any hiss or noise floor of your receiver at idle. The question for you to decide is just how audible it is and whether it interferes with your movies and/or music enjoyment. Generally, if you can hear the hiss at your seating position - then you may want to consider an upgrade in that area. However, if there is a hiss at idle, audible just inches away from the speaker - that would be more normal on the relative scale of things. Carl.

Klipsch Employees Trey Cannon Posted December 6, 2005 Klipsch Employees Share Posted December 6, 2005 Most amps / receivers have some output even with the volume turned all the way down. The klipsch products are so "easy" to drive that they will "play" even with the volume down. The only way to fix this is get a better receiver / amp or use the mute a lot. Better = a larger siginal to noise ratio. 105 or more... and damping factor 400 or more. Quote Link to comment Share on other sites More sharing options...
cjgeraci Posted December 6, 2005 Share Posted December 6, 2005 Trey, thanks for providing the technical terms: Yes, that's it, signal-to-noise ratio. Carl. Quote Link to comment Share on other sites More sharing options...
mtber101 Posted December 7, 2005 Author Share Posted December 7, 2005 Thanks guys.. that's what I figured. I just have this receiver right now to hold me over. Seperates along with completing the HT are hopefully in the near future. In general what seperates can you all recommend that are quiet...maybe even dead quiet.

lavinius Posted December 7, 2005 Share Posted December 7, 2005 I can't hear anything from my Yamaha 657 with the volume completely down or on mute Quote Link to comment Share on other sites More sharing options...
RayoVac Posted December 7, 2005 Share Posted December 7, 2005 Another vote for NO hiss. I have RB-75s, RS-7s and RC-7 used to run them off a Yamaha 5790, Now the Yammi Pre/Pros and a B&K 125.5 provides the power. Have never had Hiss or Hum problems.

mtber101 Posted December 7, 2005 Author Share Posted December 7, 2005 Figured but wanted to double check... would you say they are totally quiet? Quote Link to comment Share on other sites More sharing options...
lavinius Posted December 8, 2005 Share Posted December 8, 2005 do you get a hiss or hum? did you have that hiss/hum before? if you still have you old speakers did you reconnect them and listen closely? is the hiss/hum still present at say 5% volume? Is your amp/cd/dvd earthed properly (if they are older or if you use a PHONO input)? are your carrier cables ballanced or unballanced? does it do it on Video1 Video2 Video3 Tunner or might have you on your amp ? This are questions I'd askmyself first then try and put my finger on it but like someone mention ...
