-9 g/r...gate off...EQ 12 o'clock..operation M on the SPP800
-4 g/r...limiting +1....EQ 12 o'clock on the SMC-600

these are places to start...be careful not to overdrive the inputs..
stay with yellow peaks...not red...it's critical....
less is more, ok?

what are you wanting these to do?...... is a good question...
