Hi to anyone who can help.
We have had out LS9 for about 5 months now. At yesterday's church meeting, we had problems with one of our inputs coming in to input 9 on the console. I have rechecked the entire signal path from source and have found that input 9 on the console is definitely problematic. Symptoms are: boosting the HA gain on a particular signal (lets just say its a AKG dynamic plugged directly into input 9) the console's meter doesn't show any input signal (when cued)When I Plug an instrument through a DI, engage phantom power and there is a signal, but it horribly distorted and very low level indeed. Other than that, there is an audible hiss coming from that channel, when turn channel 9 off, and the noise is gone.
My question is: do you think I have a pre-amp thats blown, on that input, and has anyone experienced a similar problem?
