Neumann KH 120 - disturbing clicks???

hi,

I recently bought Neumann KH120 Monitors, and first of all I must say they sound great . BUT --- I have a Problem with weird clicking sounds that I hear coming from them (randomly, every 1/2,1,2,3 hours)?!?!
I think that it is due to voltage fluctuations in my flat, because I also had problems with the dbx 266xl (making weird noise-artifacts, etc.). What I dont understand is: why didn't I have this problem with my old my old monitors?
I had Tannoy Reveal 8D's, and they weren't connected to the ground (they didnt even have the option, tannoy claimed that it was better because that way you could avoid ground loops) -- could that make a difference? (I rather doubt it).
Another option could be that my audio interface is vulnerable to voltage fluctuations and therefore I hear clicks --- because if the monitors arent connected to the Interface, I dont have these clicks anymore. But then again -- why didnt I hear this on my old monitors??

also, saffire claims that: "The PRO 40 has its own internal power supply which will accept 90 - 250V from a standard IEC lead, meaning a transformer is NOT required to use the unit overseas." -- so voltage fluctuations should not be an issue IMO..
But I also doubt that it's the monitors fault...

The monitors are connected to a power distributor (where also the rest of my equipment is connected), which is directly connected to a power socket -- nothing else inbetween. Also there s no 2nd power distributor connected after the 1st one...

Any ideas on the cause of these click-sounds?? it's really annoying...
thx in advance

lol lustig dass ich deinen thread find

Wenn das problem nur ist wenn es an deinem Interface angeschlossen ist kanns sein das es durch spannungsschwankungen(der erde) zu einem potentialausgleich zwischen interface und boxen kommt. (normaler weise sollte das egal sein wenn alles gscheit geerdet ist,vorallem wenn interface und boxen auch am gleichen verteiler hängen, aber bei dir im zimmer hatten wir ja schon öfter probleme, also vl liegts generell an der erdung von deiner wohnung) Außerdem kanns sein wenn in deinem Stromkreis (keiner weis genau ob das "nur" deine ganze wohnung ist oder ein paar nachbarn auch) ein gerät ist das ab und zu eingeschalten wird und vielleicht nicht gscheit funktioniert das da strom gegen erde abfließt, in so einem geringen maß dass der FI nicht fetz, und so was ins erdungsnetz eingespeist wird.

(kannst dich erinnern, wenn du am heisl licht aufdreht hast, hatten wir im wohnzimmer auch erdungsprobleme als wir mitn mario den track gmacht haben??)

probier einfach mal den groundlift von den neumännern...dann sollten die das gleiche erdungspotenzial wie das interface haben. Das würd auch erklären warum dus nicht bei den tannoys hattest. Oder zumindest viel viel geringer. (außerdem vl hattest dus bei den tannoys auch, nur weil die nicht so impulstreu/ehrlich/hochauflösend waren hast dus vielleicht garnicht gemerkt, aber das glaub ich eher weniger )



ps: ich glaub der High-End thread ist da eher falsch, 1. sind die kh120 noch lange kein high-end und zweitens sind da weniger leute, ich würds am besten in so much ger so little time geben, da wird dir sicher schneller geholfen

cheers

Do you have a proper high-end Power Conditioner to use instead?

If you disconnect the input cables, do you still hear the clicking sounds?

no, unfortunately not... but i'll consider buying one if there is no other solution

no, there is no clicking if it isn't connected to the interface.

It appears that the noise is coming from whatever is feeding the KH120. Maybe the source needs to be grounded?

Sounds like you have a clock issue, not a speaker issue.

I'm pretty sure now that it's the interface... but it is grounded.. hm, you think clock? what could I do to check if its the clock?

Es ist sicher das interface....wenns ohne interface angesteckt nicht ist.

Das problem besteht auch wenn kein audiosignal durchs interface kommt oder?

dann würd ich die clock eher ausschließen...außerdem sonst hättest es auf den tannoys auch gehabt, vermute ich mal.

ich bin mir zu 99% sicher das es iwas stromkreisbezogenes in deiner wohnung ist.
vermutlich was mit der erdung, sonst wäre es mit groundlift nicht seltener geworden.

wahrsch iwelche potenzialausgleichungen zwischen interface und boxen...

schnapp dir enien multimeter, miss mal phase zum nulleiter über eine längere zeit und dann die erdungen zueinander bzw nullleiter und erde..

wenn da was komisch ist ruf bei der hausverwaltung an und beschwer dich ^^

cheers

Disconnect your speakers from your Interface and plug in headphones instead.
If there still are clicks, take your interface to other rooms or even better to an other house, and try it again.
I wouldn't recomend measuring the electrical outlets if you are not familar with this.

Steck die Boxen mal ab und steck einen Kopfhörer ein.
Wenn du noch immer Störgeräusche hörst, teste dein Interface mal in einem anderen Stromkreis / anderes Haus.
Wenn du dich mit Elektrontechnik nicht so auskennst würde ich an deiner Stelle lieber nicht an der Steckdose messen.

wow....der ärgste österreicher thread hier

voll, probier das mal mit den KH....ich vermute das du da keine klicks hören wirst.
wenn das so ist, ist es noch wahrscheinlicher das es am stromkreis liegt.
schließlich werden die KH NUR durchs interface geerdet, das heißt also die potenziale müssen 1:1 gleich sein.

I dont have the clicks on the headphones... i'm pretty sure it is my crappy electric curcuit at home... but what can i do against that, apart from installing a new curcuit at home (if that is even possible in my flat..)???


bei kopfhörern hab ich es nicht.. ich bin mir auch ziehmlich sicher dass am stromkries liegt.. aber was kann ich dagegen machen außer mir einen stabilen stromanschluss ins zimmer zu verlegen?? wenn das überhaupt möglich ist, vllt ist das im ganzen haus so...
