Mixer making sounds and Audio Dropout


Over the past week my x-1800 has developed an issue where the audio becomes very muddy and cuts in and out rapidly with a physical clicking sound coming from the mixer itself. The clicking from the mixer almost sounds as if it is trying to switch inputs quickly( ie. from phono to line or digital). It has happened with every setup I have played lately, Mixer and two vinyl records, Mixer and two sc5000, and Serato Dvs Mode. The firmware is 1.1.1 and I am hoping that is the culprit because I can’t remember it happening before updating…

Tonight I had finally convinced one of my die-hard to play on the primes and it really dampened the night. I recorded a video to upload where the problem is occurring.

After a night of flustration, I unplugged everything to the mixed except the power and was able to record a video of it making the clicking sound. It was in and out of this clicking mode for the duration I kept it on and with no outside influences or inputs to affect it. Anyone else have this issue?

Audio output problem

Don’t think it’s firmware. If it was firmware then everyone on the same firmware would have same issue probably something close and local to your one mixer.

My mixer had a clicking like that from its protection circuit in one certain venue only and it turned out that their PA system was passing actual VOLTAGE back down the the xlr leads to the mixer and the mixer was protecting itself from the PA system.

Yours is clicking it’s protection circuits evencwoth no PA system plugged in so maybe something has already damaged the mixer.


I was leaning toward thinking it was an issue with power feedback also. But then I plugged it in without any external connections and it was still making the sound…


Hi wgarri20. Whatever caused the issue to start, the unit will need to be returned for a repair/replacement. Please contact your retailer/dealer to arrange this.


Will do. Thanks guys! :metal:


Please check the power cord for ground connection. In my very similar case it was a internal ground conection problem.Titing the 3 screws in the botom plate center can be the solution. Best regards Philipp


Perhups by getting the white scin, there don’t conect well one of the 3 ground wires to the botom plate. https://www.youtube.com/watch?v=vp9cwBKPY0k Best regards Philipp


Just throwing my $.02 in here. This exact same issue just started happening last night, luckily in my garage and not at an event. Denon Support has advised that I send the mixer in and I will have a repaired or replaced model within 2-4 weeks. SMH. Not happy about this. My first major issue with this setup in under 1 year.
