I’m angry & disappointed

Are all Usb Mixers this noisy?

Hi again
Still having a big problem with this noise issue which is making the mixer unusable frankly. I am very disappointed. I am very new to all of this so it is probably me being stupid. One observation which you might be able to explain to me is this:
When the USB source and Phones source are routed differently (i.e. one button up and one down) there is no noise. As soon as they are set the same the noise is there. Why is that? Also with the mixer (with nothing going into it) connected to the Macbook (running on battery only ) and the earth to the mixer disconnected, the noise is still there.(So where is the ground loop there?). Also it is only when the Input setting in Tracktion 6 is set to USB Audio Codec that the noise appears. If it left on 'Built in input' all is quiet.
Beginning to regret the whole USB thing!! Help!!!

  • Hello Richard,

    Thanks for the post. I'd like to help but you didn't list which Alto mixer your using. Please list it and I can help you out.

    Regarding Ground Loops, you may be experiencing that. Check out this helpful link here to help you out.

  • I'm having exactly the same problem as Richard Vinson (the post above). It's not a ground loop issue as the whine still occurs when connected to my macbook on battery power. I'm using an Alto 1202. The sound is pure when not connected via the USB. As soon as the USB is plugged in there is the high pitched whine again. It's not usable on recordings. Any help or advice would be greatly appreciated. Thanks, Jim

    • Thanks a lot I'm not going to break the cord. i paid too much money to be stuck with something i can't use.
    • Hi Davis.

      Yeh listen up. It's a great pity really. I had the LIVE802 and I loved the mixer i.e. the build quality etc was outstanding as was the aesthetics. But with this issue I could not use it even for simple playback via USB to my Alto 215 system as I could hear the whine through the PA. And while some may have been lucky with this ground loop issue it didn't make any difference with me. Not only am I 100% sure (due to the way I've wired these things) that there could not have been a ground loop but I had the same issue simply connecting only the mixer to a notebook running on batteries (and same thing i.e. the moment the USB was plugged in there was this whine through the notebook's speakers and it was also recorded in my DAW). Somewhere on these forums there is a highly technical explanation of what could be causing this (could not find it this morning but it's here somewhere). I unfortunately had to settle for a Behringer but it does the job I guess and so far so good. Would have preferred to have been able to keep the Alto though. On the other hand: I do find it hard to believe that it's a global "across the board" issue given the number of mixers that Alto must surely sell worldwide i.e. only a handful of people are posting on these forums about this issue. Don't have the answer really. Maybe they're contacting Alto direct and don't know about these forums??? Not sure. I will say this though: Alto could not have been more helpful and understanding i.e. there was no issue from their side after I'd told them of the exhaustive tests that I had done in an attempt to remedy the problem.

      Anyway. Good luck.

      Regards,

      Dale.

    I am setting up an Alto Live 1202 using Tracktion 6 software on an Apple MacBook Pro running OS X 10.9.5
    As soon as I switch the input to the USB Audio Codec, I get a high pitched whine which remains audible even through recorded material. Any thoughts as to the cause would be gratefully received.

  • I sold my 2404 mixer, but still have a second flight case for one and was tempted to buy another one of these mixers, until reading these posts....I had dreadful low level hum when the mixer was connected to a laptop via USB - whether on battery or mains - which I thought was ground loop noise, though I had never experienced any such phenomenon on any of my other equipment, ever (I have been around a while). It made the mixer useless for USB recording. I'm definitely not buying another one after reading others' complaints and viewing the poor customer service responses. Avoid
    • I'm afraid I returned my Alto mixer to the seller and got a refund; I bought a Pro FX12 instead that has a silent USB connection and does the job, a few quid more but with a noisy USB the other one was useless for what I wanted to do.
    • Mine was an Alto Live 2404, supposed to be top of the range. USB noise made it useless for recording. Glad you posted that - a reminder not to get another Alto mixer. Note also how their customer service are either dead or asleep.

    This reply was created from a merged topic originally titled Need a solution to stop the 1202 USB whine!.

    My Live 1202 Mixer has a whine when connected through USB. I had posted several months ago and tried to deal with it. Since then I have noticed several other post with the same problem. A better USB and change of venues and the problem is still there. It comes through on recordings also. Surely Alto has taken note of this issue and acted to correct this problem. I have several of your products and would like to purchase more at some point but the whine is like a thorn in my side. HELP!!!

  • Well, I have a new replacement Alto Live 2404 to replace the first 2404 mixer that had a completely bad usb out of the box. The new replacement has the dreaded high whine when ever I'm going into Reaper or VSTHost, which all use ASIO4all (Play back or Recording). My Windows lap top does not make the whine when going through Windows Media Player to play music to the mixer? Running my Sony Vista lap top on battery doesn't get rid of the whine. I have seen other USB Mixers from other company's having the same problem on line? I wonder why WMP doesn't have a whine (maybe because it doesn't use ASIO4all)? In Reaper I've tried all of the other "Audio System" alternatives besides ASIO, they all have the whine. This is the million dollar question causing customers to return their mixers and get a refund. I love my mixer, it looks and feels great. It also sounds great...I'll find an answer to this problem one way or the other. I don't think it is a ground loop problem because it doesn't happen when sending music to the mixer from WMP and it still has the whine when there are no cables hooked up except the USB and the lap top is running on battery using Reaper or VSTHost for playback/record. I have a two plug isolation transformer that I'm going to power the lap top and the mixer at the same time to see what happens as far as a ground loop issue is concerned. Wish me luck...
    • After completing all my trouble shooting steps (see my post on "Alto Audio Codec not being seen by Reaper"....solved) I am confident it's not a bad connection or ground loop. It's a malfunctioning USB, so I'll return it to Alto for a 3rd replacement. I do electronics work and sometimes lemons get through the Quality Control Testing. A small inconvenience for such good engineering and design. It is what it is...Can't wait to stop using my two Bheringer 4 channel back up mixers for gigs however...LOL..

  • Got my third mixer from Alto, same noise problem when connected to Reaper DAW via the USB with Windows Vista and 8.1, only now this 3rd mixer has enhanced noise when the mic is connected to a channel strip. I posted a work around in the "ideas" section that 100% gets rid of the bad noise interference. You have to use a Behringer UCA202 connected to the RCA in and out's of the mixer, silent bi directional operation with your DAW. This has been a problem for a lot of people since the Alto live series was released. This mixer line would take over the mixer market at this price point if it wasn't for this noise issue. Somebody is dropping the ball by not fixing this at the manufacturing level. I'm keeping the mixer because it's a great mixer despite the USB problem. After my warranty is over I'm gonna open the mixer up and fix it, even if I have to circuit bend it's original design. As the owner of InMusic is fond of saying..."A Challenge is an Opportunity". Yup...

  • Got my 4th replacement mixer today and now I have a working DFX OUT jack but the USB noise is still there with Reaper. I have a High Speed Optical USB isolater coming in the mail, so maybe that will fix the noise issue with the DAW/USB connection. I'm keeping this mixer even if the isolater doesn't fix the USB noise because the Behringer UCA 202 to the mixers RCA plugs does, but you lose a few options. Thanks

  • Hi.

    Well this is just FANTASTIC i.e. I purchased an Alto 802 just yesterday and have the exact same problem (have posted details on another thread and reported the issue to Alto and await a response).

    Did you ever resolve this issue Jesse (or anybody else)???

    Regards,

    Dale.

  • Hi Garner.

    That's interesting. Pity. I never thought to try that. And I say "pity" because it was a great mixer i.e. construction quality was great. Only other issue was that I could not solo the tracks (but would have lived with this in the interest of having a matching Alto system). I had to return the mixer and Alto were quite fine with this so there was no issue. But yes: great pity. Glad you sorted your problem out though. This being said: I'd find it a stretch to believe that every single person that has reported this issue could have solved it by breaking off the ground prong (more often than not these things are supplied without a ground prong i.e. depends where you are located I think). Jesse (above) would be able to confirm this though I'm sure (given that he ended up having no less than four Alto mixers supplied and all with the same issue).

    Regards,

    Dale.

    Hi All, my Alto Live 802 bought new just 1 week ago has the same issue of high pitched tone when the 'USB In' line is in use.

    It's definitely not ground loop, as I experience it with only the following connected to Alto:
    * Alto power cable
    * USB to Macbook (running on battery)
    * Headphones

    And only when I launch a DAW (tried both Ableton and Garage Band) does the high pitched tone appear. But as others have stated it makes the mixer unusable when wanting to record, which was the main reason I choose this product.

    'Breaking off the ground prong' does not resolve this issue for me. In fact I didn't need to break anything as I have a converter with fake ground prong.

    I'm disappointed by this issue and reluctantly I'll begin the journey of returning this to Alto.

    Regards,
    Benny

  • I felt the exact same way . With no help. After spending $100s of dollars and rewiring my full studio with that buzzz. All I needed was this kind of cable. Notice the magnet on it. On the cable make sure that magnet side is where you want to plug into the mixer or anyother device. If the magnet is on the usb side it will not work. I hope this helps . Google Slump Musiq.

  • @Davis Mallory thanks for sharing your experience. Today I bought a small pack of Ferrite Cores and installed them on to my USB ab cable (as a number of shops I tried didn't have the ready-made cable with magnet), see attached pic. But unfortunately this did not work either, the high pitched tone continues to appear.

    I completed the Alto online support form a couple of days ago but nobody has gotten back to me yet. I've now exhausted all suggestions on this forum, which I was glad to find. A similar mixer in spec and price is the Mackie ProFX8v2, so assuming my Alto is returned then I might go with the Mackie.

  • Well, I have tried the ferrite cores added to my USB cable as well as ordering a Tripp-Lite cable with built in ferrite, and neither offered a solution to my high pitched whine. I wish I would have tried this 802 before my return policy had run out. I am surprised that there has been no fix offered for this. I know that this company has had loads of customers complain of this.

    I also spent hours eliminating "suspects" and it all came down to this: As soon as I load the usb driver, this unit generates noise.

    I saw this as well while looking for a resolution to my 802 noise issue:

    http://community.altoprofessional.com...

    And this all leads me to suspect that it's not a bad USB port or noise induced into the USB cable, but an issue with noisey/faulty digital audio converters in the units.......both mixers and other products that may share the same DAC design.

    I am bummed out here. I feel like I lost on a NEW product. I could have ALTO replace it, but unless there was a design update in the replacement unit.....we will have the same issue.

    • Before You buy something from Presonus please check support page. I sold my Presonus 1818 VSL card... My Friend have a MacBook and he use know this card only for live sesion. At Homestudio he use Presonus card with Fire Wire on PC and working really good. But 1818 VSL (mixer 1602) on PC (USB 2.0) that was only this same thing; Houston we got the Trouble ! I decide to buy Alto because I use this mixer only for live gigs (guitar and vocal). Quality and Price its really good (for me better than Behringer, Soundcraft, Yamaha MG, ). Before I bought this mixer I think about Multichannel Analog mixer UFX Behringer and Soundcraft Multitrack but Price was too high...
    • If your not running usb it's quiet. But in my case . I bout it just for usb but the unit is crap for the money. I felt like i was robbed I lost my paperwork for the mixer. Unless I'll return it. I only had it for about 6 months or less. And very disappointed

  • I believe these mixers use the TI PCM2900C device internally for the ADC/DAC USB. They are prone to 1KHz breakthrough from the USB packets when sending data. They have a internal regulator but the datasheets recommend bypassing this this with an external regulator to get the required performance. There nothing you can do externally. If you are just using the DAC only (playback) the tone will disappear.

    Buy a Behringer UCA202 which is cheap as chips.

    I have bought a alto live 1604 When I connect it via USB connection to record live hardware I get a high pitched noise when I am in a Digital Audio Workstation. The DAWs I have tried it on are Reaper and Logic getting the same result in both the minute I open them the high pitch noise starts and is continuous? is there a way to get rid of this ? I tired to ignore it but when I record hardware it effects the sound that has been captured.
