Buzzing noise with Alto TX12 speakers and found there was a buzzing noise coming from the speakers

Hi

I did my first gig with Alto TX12 speakers and found there was a buzzing noise coming from the speakers, is there any way I can stop this happening? I use an Alto Live 802 mixer and red and white RCA cables from my laptop into the mixer and XLR cables from the mixer into the speakers. Thanks in advance.

  • Hello Mike,

    Thanks for the post. I'd like to help! Your laptop or laptop power cord could be the problem. Make sure EVERYTHING that you're plugged into is grounded and you should plug everything into a surge protector. Could you confirm this?

  • Hi Chris I am not sure what you mean about grounded. I think the extension has surge protection not sure though, I had the speakers plugged into the sockets on the wall and the rest into the extension.

    • Hello Mike,

      You also want to use the best ports on your computer for recording devices. If you have a desktop or a tower, be sure to connect your audio interface to a USB port that is on the back of the computer. if you're using a laptop, make sure you connect the USB port closest to your power supply. Generally, USB ports on the front of the computer, on the monitor, or keyboard don’t perform as well as those on the back. This can help prevent noise, dropouts and connection issues.

      If you use hubs (which I don't recommend), use powered hubs. If you have to use a USB Hub to connect your device, use a hub that has its own AC power adapter.

      If necessary, upgrade to a premium USB cable from your local electronics store. If you live in an area that has a high degree of radio or electrical interference, and you experience noise or hum when using USB audio, upgrade your USB cable to a premium cable with extra shielding and a Ferrite Bead (a cylindrical bump on one end of the cable) which can filter out some external noise.

      I don't use a usb I use the red and white RCA cable via the headphone socket on my laptop. I have ordered a Surge protected extension cable. Is it possible to buy say a 6 metre power cord for the speakers? That way I can connect the speakers to the same extension along with the Laptop and Mixer.

      The lights should be ok in a different extension though won't they? I wont have enough spaces if not.

      I hope to sort this out before the weekend.

      Thanks

      Mike
