problems with behringer ddx3216
hi guys,
it's ryo writing from italy. i've been using a behringer ddx3216 digital mixer with a 2xADAT expansion with my DAW since about 3 years. now i have a problem: even with no attached cables, every some tens of seconds any analog inputs "receive" a (short) signal at about -20db. the strange is that not only i can see the fader leds on for a while, but even the "signal" leds on the input pane go on. just like if something were attached in the inputs and generating a signal. do you know if there's something i can do before carrying it to the assistance? thanks in advance -- ryo |

These things are generally not user-servicable at all. If it was, and you were qualified to service it, you'd be into it already and coming in with more detailed questions. Have you relocated? Or has something that creates EMI (radio interference) moved in next door? Industrial machinery? Medical facility? |

What it looks and sounds like is the number 1 diagnostic. d -- Pearce Consulting http://www.pearce.uk.com |

Grounding problems? Check your studio power?

Could be something as simple as a dirty connector inside the desk. Sudden drops of voltage to the IC's will produce audio spikes. Try banging the desk with your hand - do the lights flicker with mechanical shocks? Gareth. |
