Circuit Board Assembly
You're ready to begin assembling your XAMP-M2 circuit board. Assemble the board in the order listed in Table
1. The components for the standard kit (in bags marked ‘Bag A’ and ‘Bag B’) support the default configuration:
UNBALANCED signal mode. If you purchased the BALANCED signal mode upgrade, you will have an additional
bag labeled ‘Balanced Mode Upgrade’, which contains the components required to configure the XAMP-M2 to
support balanced input. Table 1 below lists the parts and assembly steps for the standard board. Table 2 has
the parts lists and specific instructions for the Balanced mode option. Use the install check boxes on the right
side to track your progress. The 'Install Notes' column will alert you to any special instructions (listed below) for
each of the components. We recommend reading and understanding all the design notes before you start your
assembly. The PCB has large, heavy metal planes, which makes de-soldering components extremely difficult.
Soldering a component in the wrong location may be a difficult mistake to recover from.
