repetitive clicking noises after a couple of hours of use - Coffee_fan - 28-Jun-2016 Hello, I am new to this forum as I bought a Devialet 200 a couple of weeks ago. I am having a problem which I do not think I found an exact replica in this forum, but something along the lines. I have been playing my D200 with several speakers. One set of speakers the Bryston Model T signature loudspeakers, which are 4 ohms. At some point, the speaker started emitting cracking noises from the twitter. Turned off the amp and back on and the problem was gone. Then another time, I hooked up a pair of KEF LS50, after a while a ticking noise, with possibly a frequency of some 40 to 50hz started coming through the speakers, not too loud to surpass the music but clearly noticeable. I turned the amp off and then back on and things got well. Nevertheless, after a while, the tweeter of the LS50 started sounding harsh. I turned off the D200 for some 20 minutes and then back on and the symptoms seem to have disappeared. My question then is what is this noise? BTW: I am on the latest firmware. I figured that it may be one of the following:
Thanks. RE: repetitive clicking noises after a couple of hours of use - Pim - 28-Jun-2016 Hi Coffee, Welcome to the forum! 1. For EMI / RFI to get into the Devialet and have the impact you're describing you would have to have something like a mobile phone or some other transmitter close to the Devialet. Normal interference from power cords etc. wouldn't do that. 2. This could be it but that means the amp is broken. 3. I have 4 Ohm speakers and I can drive them as hard as I wish so that's not it. Unless they drop to 1 Ohm and you drive them hard. I hope you're aware of the AIR issue? What input are you using? Do you hear it on all inputs? I hope these answers / questions help RE: repetitive clicking noises after a couple of hours of use - Confused - 28-Jun-2016 Have you checked the temperature of the amp during one of these problematic episodes? (and indeed when it appear to be running fine) This might tell us something? You can scroll through the display screens on the Devialet to see the temperatures of the Class A amp, class D amp and power supply. RE: repetitive clicking noises after a couple of hours of use - Teliaved - 28-Jun-2016 Hello Coffee Can you try with the D wifi turned off ? Regards RE: repetitive clicking noises after a couple of hours of use - Dr Tone - 28-Jun-2016 Yep, turn wifi off. It's a noise magnet. RE: repetitive clicking noises after a couple of hours of use - Damon - 28-Jun-2016 Welcome Coffee_fan to our jolly little club. I had some clicking noises when using a turntable that I believe were related to the cartridge impedance/ load settings. I know nothing about that stuff, but I know that changing the phono settings in my configuration solved that bit of noise. Otherwise, are you using USB as an input? I recall, from perhaps a year ago, that there can be some intermittent clicking noise associated with the USB signal. Again, I'm short on detail or specifics that could help you. The 40 or 5h Hz noise sounds more like a grounding problem, or a loose connection. The threads may have the words 'click' or 'pop' or 'stutter' in the title. I see that you have quite a collection of computers (as well as speakers); are the noises present when using both or only one of the computer inputs?

I will check the temperatures, do you have any idea what are acceptable ranges?

Thanks @DrTone and @Teliaved, I will disable WiFi, because anyway I had noticed that for any bandwidth above 88.2 it may stutter, so better go direct ethernet route. Pierre |
