Hi!
1.) Today arose the point of pot orientation... :
.I suppose that the black dots on the schematic pots signals the
turn direction of the potentiometer as viewed from the front (shaft side). left 1, center 2, Right 3.
So, for example VR7 comp ratio pot, turns Clockwise to the right... this means pin1 is gnd... and pin 3 is connected to R26/D5 right?
The other pots are a bit more clear:
VR6 threshold pot turns clockwise.. so pin 1 is connected to V+ and pin3 to V-
VR8 gain pot turns clockwise... so pin 1 is connected to V- and pin 3 to V+
Symmetry pot: pin1 V+, pin 3 V-
Attack: pin1 V- , pin3 V+
Release: pin 1 V+, pin 3 V-
Any correction is wellcome!!
2.) To recap a bit, the pole at SW3a connected to R26||R31 is the point where to connect the buffer to the compression meter. (made with LM3914).
3.) Input and output levels are measured at master in/ master out points, with a peak meter made with LM3915.
Thank you for your advise!
