OK....Fixed!!!!!
Revision 1.2 list contained only 11 errors/small fixes.
I stupidly sticked to original console's manual, really, GSSL and 4000 bus compressor
doesn't have too much similar - except both are compressors
I got ratios 1:2.05, 1:4.2, 1:10.5
(measured: threshold@-12db, input-10db, ref, input+10db).
Seems within tolerance.
The threshold is not same at different ratios (within 3db, tolerable),
IIRC original compressor have same behavior.
Updating the pcb rev.1.2!
Some questions.
Possible to do front panel as 3mm thick black glossy PCB(and it will look really cool),
I prefer it to black anodised aluminium with silk screening.
Possible as well to make nice metalwork (1 mm thickness aluminium bracket to hold everything).
To do this, we need minimum 50 orders.
In this case, if PCB set will be roughly EUR85,
full PCB set with metal works and front panel will be arround EUR 155.
Please vote if price is OK and which option do you prefer
(only PCB's or full set with front panel and bracket).
