Bose L1 OG tower PA front panel I/O and control board

Description

Front panel input/output and digital control board for the original Bose L1 tower system. Removed from a unit that wasn't working because the auxiliary power supply board was blown, which makes it impossible to turn on the system. All the other power supply and amplifier modules still worked, so there's no reason to think this front panel assembly also wouldn't work, but I have no way to test it.
