Hi folks.
Steen had an accident.
A duff cable allowed phantom to short to ground on preamp one of my presonus fire studio mobile.
The result? Preamp two works perfectly with and without phantom, but preamp one has low signal throughput and a lot of very active noise.
By active I mean not a consistent hum or buzz. More of a wishy washy wind noise.
Given that both preamps work, technically, and the phantom supply is clearly still live, I was hoping I'd burned out a 6k8 on channel one,
but opening it up and inspecting revealed nothing obvious.
Does anyone have any suggestions for testing, troubleshooting, or repair?
If you need any more info just ask.
Thanks folks!
