(24) SSL 4000 Series Mic Pre amps. Racked with dedicated power supply and patching panels x24 in/out on XLR. This system was recently fully serviced and sounds great. The mic pres have Jensen transformer and are upgraded from the console version producing roughly 78 db of gain. 48v phantom, phase reverse and a 20 db pad on every channel.This is rare opportunity to own 24 high-end pres at an affordable price. Full working although consider the modules are roughly 30 years old, so don't expect them to look like new! Also, one of the caps is missing - purely cosmetic - but worth mentioning.
