Locate the DIP switches, which 
are found on the underside. 
Each switch is arranged in a 
mirror pattern for left and right 
channels.

Start by selecting each DIP switch 
for the recommended impedance 
of your cartridge as shown in the 

Input Impedance Settings chart

.

Next, select the best gain setting 
for your cartridge using the 

Cartridge Output Settings chart

 

and set DIP switches accordingly.

For Moving Magnet (MM), start 
with 40dB. For Moving Coil (MC), 
start with 60dB. An additional 
6dB can be added via DIP 
switches 1 and 12.
