Hello. I was running a practice and service this morning and had problems with digital distortion/robotic/low fidelity sound on my house speakers every 20 minutes like clockwork. It would last for 1-5 minutes. Monitor/in ear system channels not impacted. I listen to each input output in headset all sounds normal. We have the Advantis board and then several A&H digital snakes. Where could this issue be coming from?
I assume when you listened to all inputs and outputs that included the main mix out with headphones?
What processing is between the mixer and speaker system?
How is the main system being fed, analog, AES, Dante?
I will collect more information on our front of house boxes and amps. I did listen to each channel on the board during the event and all sounded normal in the phones but each were distorted in the house speakers.
Based on what you have said, it does initially sound like an issue after the console as mikec hinted at.
That or there is an issue with the output sockets you are using for the L/R.
Do you have other spare sockets you can use to test with?
