Cartridge Loading Adjustments

Prior to making any of these adjustments, always

disconnect the AC power cord and all interconnects

from MOON 610LP. We strongly recommend using

the

pen shaped

plastic hand tool

that we have

included with your 610LP as it was specifically

designed for this purpose. Using another tool made

from a material other than plastic may damage the

DIP switches and/or scratch the painted surface on

the bottom of the 610LP’. Finally, to achieve the

best possible sonic performance, it is absolutely

necessary that all settings be identical for both the

left and the right channels.

In the following examples,

the color

white always indicates the

position - left (‘ON’) or right

example to the left, the DIP switch is in the left

position (‘ON’).
