Hi everyone.

I've just finished the assembly of this LA502 module and i'm now onto the calibration and setup step.

Power voltage seems fine, i'm getting +/-15,95 VDC. Compressor Check seems to be fine too, Gain and Peak pots seems to work as expected.

When I'm calibrating the Meter,  I can get the -3 / -6 and -9 LEDs lightning without any trouble while adjusting P4 / P5 and P6 trimmers at 10,6 / 7,5 and 5,3 VAC signals on output. But I can't get -12 / -16 and -20 LEDs ligntning at 3,72 / 2,4 and 1,5 VAC output.
On the other hand,  when I'm switching on "6" on the ratio switch and turning the Peak pot, these LEDs are lightning all 3 at the same time when reaching 0,60 VAC output. Same thing with a "20/limiter" ratio when reaching 0,56 VAC. P7/P8 and P9 don't seems to have any effect on the lightning (or not) of their respective LEDs.

I've already checked my solder joints and reflowed a couple of suspicious joints, but nothing changed. 
Any ideas ?

Thanks!
