7.3 Initial operation
The power connector’s (8) pin-ou t in top view (refer to fig. 2) is assigned as
follows:
Bottom to top, left to right. Thus pin 1 is located at bottom left, pin 2 above pin
1 etc. Pin 15 is at bottom right, pin 16 at top right.
Pin 1, 2 = -12 V (labeled with a triangle)
Pin 3-8 = GND (regarding ground, 0 V), located outward on all jacks
Pin 9, 10 = +12 V
Pin 11-16 = not connected
To hook u p power to the modu le, connect one of the IDC-connector of the
included flat ribbon cable to the box header (refer to fig. 2). Observe guide key
for the polarity of the connector in order to avoid pin reversal. The red tag of
the cable is to match the triangle-label.
7.4 Calibration
All trimmers are 12 gauge trimmers, i. e., 12 turns are needed to cover the
entire range. the trimmers P1, P2, P4 and P5 increase their parameters when
turned clockwise. The feed-through trimmers P3 und P6 are zero-adjustment
trimmers and should better be untouched!
Note: This is a complex full analogue working circuit, where scattered
parts will heat up more or less. Moreover big capacitors with large time
constants need time to charge. This causes to a so-called transient where
the device achieves its final state.
Clear text: "Frequency" and "Resonance" will drift more or less after a cold
start and achieves after 3 minutes about 95% of the as last set values.
