12V Trigger Connections
The 12 VDC trigger connection shown can be used to turn
the amplifier on when the preamplifier turns on. This trigger
will actually trigger with any switched DC Voltage from 5-12
VDC; however, the majority of home theater components use
a standard 12 VDC trigger connection for this function. This
is the preferred connection as it has the greatest degree of
reliability.

Regardless of the configuration used for the XPA-1 amplifier channels, proper connection of each
speaker is essential.
The 5-way binding posts can accept bare wire, spade terminals, and dual
or single banana connectors. Spade connections or banana plugs ensure a simple, solid fit in the
terminal whereas bare wire may be awkward when
the terminal is screwed down to compress the
wire into place. Keep in mind that if you use “dual banana” plugs and “stack” them, you will be creating
a parallel connection and this amplifier is not rated to play below 4 Ohms per channel.
Never switch anything that plugs
directly into the wall with this trigger
connection. This action will damage
the unit and VOID THE WARRANTY.
Connection Diagrams
There are two groups of speaker terminals
and each group is connected in parallel.
Which is to say that the two terminals on
the Positive are in parallel and the two
terminals on the Negative are in parallel.
