Dual-Channel Connection
The Channel 1 Speakon connector has the added
feature of providing both speaker outputs on a single
connector. This allows you to use a single cable to carry
both channels from the amplifier to the speakers. Refer
to the hookup diagram on page 7 for a typical applica-
tion using the dual-channel connection.
Many speakers with Speakon connectors provide an
Input connector and a “Thru” connector for connecting
a second speaker in parallel. You can use the Thru con-
nector on the speaker cabinet to connect the Channel 2
amplifier output to the Channel 2 speaker.
For the cable connecting the amplifier to the first
speaker, wire all four pins in the Speakon connector, as
shown below, at both ends of the cable. For the cable
connecting the “Thru” connector to the second speaker,
you need to use a “crossover” cable that connects pins
2+ and 2– on the “Thru” connector to pins 1+ and 1– on
the second speaker input end.
