AMX audio dropouts and controller disconnecting when playing live venues

Hi. I bought the AMX a few months back to take travelling with me. I’ve used the controller at home with no problem, but now I’m playing out in venues in Vietnam and am experienced major problems with audio dropouts and the controller disconnecting with Serato. I’ve played 4 times in the last 2 weeks, and twice I’ve had these issues, the other 2 times I’ve had no issues. The issues have occurred at 2 different venues.

When it’s playing up, I get constant audio dropouts whenever I do too much with the controller. Normally this will be if I use the jog function (search + browse wheel), but also has occurs with other controls, like the load button and sometimes the eq. Worse case scenario I get the controller completely disconnecting for about 5 seconds, then it reconnects. This also only occurs when I use the controls. It’s got to the point where it’s ruining my sets, and sounds horrible. I’ve ended up mixing on eggshells, making sure I don’t use the controls too much. I’ve got another gig in 4 days which I really need to go without a glitch, so I’m hoping someone can help!

The issue only occurs when I’m playing out, at home it’s fine. I’ve gone through and disabled WiFi, Bluetooth, ensure energy saver is turned off, and disabled auto-brightness on the screen. I’ve also tried both USB ports and a different usb cable.

I have a suspicion that the culprit could be the power grounding, which will be the next cause I will try and rule out. In Vietnam grounding doesn't seem to be a common thing, and when I play out I even get small shocks/buzzes from my MacBook and the AMX. I have read in other threads that this can cause issues with sending false MIDI data, but would this be causing the unit to drop audio and disconnect completely? If so, is there any hack or equipment I can use to fix the grounding issue?

Thanks

  • Hey sjmac,

    Thanks for posting!

    Sorry you're having some trouble with that! If the equipment is working correctly when you are at home, it is working. The common denominator for the issues you're experiencing sounds like the venues at which you are performing.

    I do think this could be related to the power being supplied to your equipment. If possible, I would advise testing with a different computer at the venue to see if you can reproduce the same behavior. When connecting your USB devices, be sure to always connect them directly to the computer and avoid using any USB hubs or adapters. I might also recommend looking into a power conditioner that you can use to power your equipment to ensure that the right amount of clean and consistent power is being provided.

    Try that and let us know how it works out!

  • Hi Nick,

    Thanks for that. Assuming it’s a grounding issue, is there any other way to avoid interference? Reports here are that it’s a common occurance to have grounding issues here, but that no one normally has problems in terms of the controller dropping out. Is this because the AMX is USB powered? Any other tips to help avoid the dropouts would be much appreciated.

    Thanks
