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’).
