Quick Start Manual
I/O In #1 NC NC +24 Vdc Gnd I/O In #2 I/O Out #1 I/O Out #2
Input/Output Please Note: Athough there are four I/O connections
there are only two usable I/O ports. Each of the two
I/O ports can be configured, via software, to be either
an Input or an Output. Each I/O port has two connection
pins. One pin is optimized to work as an Input and the
other pin is optimized to work as an Output.
Example One: I/O #1 has been assigned as an Input.
You would connect to I/O In #1 and Gnd.
Nothing would be connected to I/O Out #1
Example Two: I/O #2 has been assigned as an Output.
You would connect to I/O Out #2 and Gnd.
Nothing would be connected to I/O In #2
I/O Ports are shared between the WPA-50x connector and
the Input/Output connector. When a WPA-50x is in use, either
one of both of the I/O pins are not available for use.

Speaker wire with tinned leads can be used on
the spring loaded terminals on the speaker.
You must cut o the tinned portion of the ends
inserted into the green terminal blocks on the
amplifier so that bare copper is being captured
by the screw compression terminals.
