Probably a long shot...Looking for schematics for the repair of a Focusrite "The Liquid Channel" Primarily the mic preamp section.

Thanks
 
Are you having some issues with one / yours? And/or is it that convoluted that reverse engineering is not an option?
 
Is there THAT much circuitry upstream of the ADC's? Most of the "magic" is in the digital realm.

Buuuuut you've (still) neglected to mention the reason for this search...
 
This unit belongs to a customer and has been in my shop for over 2 years. I’ve suggested he send it to one of the Focusrite repair centers in the US. As I recall, the problem is noise in the mic preamp. Otherwise it functions properly. I did replace one transistor in the circuit and thought I had it, but the problem reappeared shorty thereafter. I will set it up and test to get a fresh perspective on the problem. Thanks
 
Internal photos of the unit would be at least interesting - there's a chance some familiar-looking topology may or may not be involved.
