I/O modular to line level and line level to modular converter

2+2 in/out level converter. outgoing and incoming level translation is fixed but can be tweaked with the 4 trim pots on the PCB, the opamp is wired as an inverter and the 100k trimpots provide R1/R2. input and output are AC coupled via 1uF caps.
