APPENDIX C: Gain Adjustment
The small multi-turn potentiometers (pot) visible on the edge of PWR I/F board between the
power connector and the row of LEDs may be adjusted to reduce the electronic gain of the
SSR (see illustration below). Keep in mind that proper location of the SSR is the best way
stabilize the SSR. Gain reduction will drastically reduce the range over which the SSR can
provide signal improvement. Rotation of the adjustment screw clockwise will reduce the
gain of the SSR. Adjustment sensitivity is approximately 1 dB per turn in the mid range of
the pot. The pots have a slip-clutch action at each end of their range to preclude accidental
damage during adjustment to the desired setting.
