CONFIGURATIONS
The PH100 Phono preamp. offers several setups directly from the rear side of the
module. It is operated by the pair of 4 points DIL: one for the Right channel, one for
the Left channel (you can also refer to the screen-printed diagrams on the rear side).
Make sure that the 2 switch blocks are in the same position.
