My X18 Is Possessed

    I just got a Behringer X18 mixer, I got an incredible deal on an open box unit from Musicians Friend. This thing has all kinds of potential, but it's possessed. Randomly it emits ear splitting sounds like you'd hear in a sci-fi horror flick that stands my hair on end and makes my skin crawl. I can't find a trigger to the sounds. Before I wrote this I disconnected the iPad from the access point, so there's no connected devices, and I still get the sound regularly. Currently I'm running 2 mics into the mixer, along with my bass through an M80. For mains I'm running 2 older Behringer 15" passive speakers. To power those I'm using my old Behringer powered mixer, running the main outs from the X18 into my powered mixer's "Input to Main" jacks. Then I'm only using the main master volume knobs on the powered mixer and have turned everything else down. Basically it's just a large 1200 watt (that's Behringer watts, not real watts) power amp. I also have 2 powered speakers on Bus 1 and Bus 2. I can get the sound through all the speakers. We rehearsed with it yesterday and for 3 hours didn't get any sounds, but today I'm getting it regularly.

    I've attached a link to the sound file, turn down your speakers before hitting it.

    Anybody else ever experience this? I don't know if I have a bad unit or some sort of random electric noise source.

    I'm pretty sure that's from Steve Miller's Threshold!


    That's probably why it's "open box". I'd get out of it if I were you.

    any way to re-install the firmware and see if the problem persists afterward?

    Good thought, I'll try that.

    Dear XontheP,

    Please allow me to introduce myself; my name is Sam Daniel and I am a Care Specialist at Music in Las Vegas, NV, USA, where we service and manage spare parts for all Music brands.

    The issue you are encountering with your X18 definitely points towards a physical fault with the unit that would more than likely require servicing to correct the fault. If re-updating the firmware on the unit does not correct the issue, as suggested by jimfist, then we would recommend having the unit exchanged through Musician's Friend as soon as possible. I would be glad to answer any further questions you may have concerning your X18. Please PM me directly or contact me via email through care@music-group.com to discuss further if necessary.

    Let’s keep in touch,

    Sam Daniel

    Specialist, Care
