Mine sits at around 8Khz once they've been on for a few mins.

I found after much tinkering that only Optical at 44.1khz set in windows works without the high pitch noise. All other settings produces the same annoying high pitch noise. It gets louder as the unit warms up to temp.<br /><br />Not sure what to do from here, i mean there isn't a massive difference between 44.1khz and 48khz for pc audio so might just live with it.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8952953525323266007.post-13671036306825752462021-06-27T06:29:39.138+02:002021-06-27T06:29:39.138+02:00Same problem here, It's incredibly annoying an...Same problem here, It's incredibly annoying and for the price it costs is a shame.

Definitely the way to go if you're so lucky to have the defective unit with you is to try to fix it. But first double check with something like a lab power supply that the problem is the one I point. If you eventually do it, you can send me some pictures and I'll post them if you like.

I too was considering...Thanks for your reply Pedro. I too was considering whether to ditch the solution. I briefly considered creating a system from separate DAC, amp, speakers... but I agree that the features and price of the Edifiers are perfect and hard to match. I tried connecting my Arcam CD player via optical and I had the same issue. I also connected it via RCA (using internal DAC) and then A-B switched between the two. The internal DAC of the Arcam CD player was much better. I've concluded that I'm probably not missing out on much with the Edifier's DAC. Instead I am going to try a Topping E30 DAC and see how that performs.JamesPearsonhttps://www.blogger.com/profile/06952680963778740948noreply@blogger.comtag:blogger.com,1999:blog-8952953525323266007.post-26194610408898337742020-10-19T22:26:37.914+02:002020-10-19T22:26:37.914+02:00Hi James,

In my case, the noise was 100% shut when I changed the input to digital or coax. You seem to experience the opposite, which is very strange.<br />The noise was temperature dependent. On a cold day, it could definitely reach 7 kHz when the speakers were just turned on.Then, the pitch ramp down noticeably in a matter of seconds as the set warmed up.<br />I definitely recommend getting a replacement if, like me, can't find an alternative that suits your needs. For me they still work fine but I can't be 100% confident now.Pedro Fernándezhttps://www.blogger.com/profile/15704566159311411008noreply@blogger.comtag:blogger.com,1999:blog-8952953525323266007.post-91273557564168285662020-10-19T14:38:19.909+02:002020-10-19T14:38:19.909+02:00Thank you for your blog post and great information...Thank you for your blog post and great information about this issue. I received a set of Edifier S350DB speakers last week from Amazon and I've been really pleased with their performance. I am using them with a PC, I already have an excellent HiFi system and so they had some unfair competition when comparing. They really do live up to the online hype, which makes a nice change. <br /><br />I have not experienced the high pitch noise with Bluetooth or RCA connections. I plan to connect a different PC to it soon and will be using the optical link. I thought I would try a Google Chromecast Audio with its optical link last night and that's when I first experienced the high pitched noise. Then the google search began and I found your post.<br /><br />I like your idea of using a spectrum analyser app to inspect the frequency of the noise. I tried it myself and I found it to be 7.1-7.2kHz. My serial number is 441406531502 and so newer than your copies. I wonder if using an external DAC will help as in my case the amplifier doesn't seem to be the noise source.<br /><br />I will request a replacement set from Amazon and see if it makes any difference. Good to hear that your second set solved your problem, is that still the case?JamesPearsonhttps://www.blogger.com/profile/06952680963778740948noreply@blogger.com
