Initial Set Up
Release the top cover by removing the four knurled screws on the sides of the chassis. At the left rear of
each circuit board, you will find jumpers which are clearly labeled for changing cartridge loading and gain
settings. The 20/20 is shipped with a cartridge loading of 100 Ohms and a gain of 60 dB. If you wish to
change those values, simply move the jumper to the correct location for each channel. Make sure that you
match the loading and gain setting for each channel.
