High Pitch Noise

Discussion in 'Recording' started by Nick Veldkamp, May 29, 2016.

    Hello, I've recently purchased some cheap budget recording equipment just to lay down some demos and what not. I have the Lexicon Alpha, Cubase LE5 that came with it, and a dynamic mic. I plug the lexicon in and turn up the line 2/mic channel, I hear a faint high pitch ring. I plug in the xlr for the mic into that channel and it gets worse. I am running Windows 10 on my laptop and have an old desktop with XP on it. On my windows 10 machine the ring only happens when I open up certain software like Cubase, audacity and even my sound recording properties. The XP desktop is a constant ring. I am not looking for a fix to the problem on my Windows 10 machine as I realize it probably isn't supported and how cubase keeps crashing and kicking out my interface.

    Following the links that Chris posted above, and having checked those things, if following those suggestions doesn't make a difference, this sounds like maybe it's a driver issue?

    Have you visited the website for your interface and made sure that you've got the latest drivers ( and firmware, if applicable) or looked for patch updates or bug fixes?
    Have you opened your control panel and made sure that the Lexicon is the only sound device enabled for your system? Or do you also have resident sound cards active/enabled as well?

    My collaborator friend has a basic system with a Lexicon Alpha and has this problem since moving to windows 10 - and Lexicon have abandoned their users and not released any windows 10 drivers anyway - and their website says not currently supported. However, his has always had higher than acceptable levels of high pitched whine - which seems to be USB linked. He tried a Focusrite device and this too had the problem but worse. After a lot of trial and error - I came to the conclusion the problem was in the DC supply in the USB cable which drives the device. The nominal 5V was dropping when these devices were connected, to just above 4V and the one computer that was clean (a Panasonic tough book running Vista) managed the full 5V when the Lexicon was attached. He bought a Roland - tricky to source, but it has a power supply and is silent.

    His Lexicon works silently on my macbook pro. I've got a Lexicon Omega which I use portable with my macbook, and I quite like it.

    Alright thanks everyone, I will try out those fixes in the link chris posted. I'm not planning on using the lexicon with my windows 10 device so what would you all recommend for using it with my XP machine (where the ring was constant no matter what software was open), I plan on installing more RAM and upgrading the operating system to vista or 7.

    I feel compelled to advise, go to 7. Vista is a pig

    any chance we can hear this noise - we're kind of guessing. I too would suggest 7 - more modern cubase versions can be clunky with OS's older than they are. I'd not expect the RAM to make any difference to the noise, but significantly improve cubase when the track counts and gizmos increase.

    Could you post a link to the noise? My lexicon is totally silent on my backup windows system and the mac.

    Now thinking about it, as silly as it seems I used to record with a USB rock band microphone and stopped doing that because of the same noise.

    Is Vista even supported anymore?
    Not that I would advise it even if it was... As Chris mentioned, Vista wasn't exactly a crowning achievement by Microsoft. It's like the evil stepchild that they keep locked away and only mention when they have to.
    Go with 7.

    Just as a heads up -- my pc had a noise that was specifc to gigabyte motherboards of a certain kind that needed something very obscure changed in the bios if I remember correctly so actually look up any info related to your motherboard as well.

    We're talking noise through headphones right?

    Alright so I have tried almost everything you guys suggested, lexicon support told me the interface is faulty. Should I send it back and get a new one or keep trying fixes? Let me clarify the situation a bit, so my microphone came with an xlr to 1/4, now I plug that into the instrument port and its perfect, crystal clear just very quiet because its for instruments. If I turn up line 2/mic to a louder point than I need, I hear the faint ring. I plug in my xlr and it amplifies it. The xlr has a bad ground in it as I touch it, it buzzes all over. (bought a $5 20 foot xlr on amazon if that says anything) So I'm stuck here, I don't know if I need a good xlr or if I need to ship out the interface, it's getting close to my 30 day warranty.

    yes -- and I'm trying to find a reference to the issue I had and the fix -- but it was byzantine -- some deep deep bios setting that was causing noise related to my MB. Until I found the fix I thought I was going to have to buy a new motherboard from a different company. When you have PC issues -- always google and search for the issue related to your actual motherboard or hardware. Look for device and driver conflicts - look for bios issues -- it can be anything.

    Alright i'll keep searching

    Also check your device managers etc - look for things like ATI-HDMI audio (if you have an ati card) and disable it. Sometimes you still have other devices trying to access audio (like you video card through HDMI) and it's getting confused with your interface and your native sound on the motherboard. Disable SLI -- see if that helps -- there can be weird conflicts. Make sure your onboard soundcard has been disabled as well.

    Yeah all that stuff I've been trying, hopefully its something in the BIOS or maybe the interface is faulty like lexicon said, Cubase keeps kicking it out because "too many errors"

    I'd send it back. Process of elimination.

    I've heard that from so many digital devices connected to computers - it's bus noise, and is common. It's digital and the harmonics mean it is very difficult to screen out. It's actually quite mild, the Lexicon Alpha my friend had grief with had that same problem but louder. His focus right replacement had the same issue, as I detailed above. His new Roland is silent. My Tascam has that sound if you turn everything up full, but at normal fader levels I can't hear it. For certain, it's coming in over the USB connection, but I've never discovered exactly why some computers suffer badly. One thing you could do is check all the usb ports are the same - if some of the ports are fed from motherboard headers, I guess it's possible the unscreened cable could internally be very close to one of the data lines and that's how it's getting in? My computers all use the same 19" rack (Carillon computers) and they have a front USB socket, and that cable is header connected and does cause a problem with a couple of devices I connect that are fine on the rear sockets? Not tried it with audio devices.
