Connecting the GPL Series to your system is easy. The rear panel includes two (2) parallel NL4 and a barrier strip
correct gauge of stranded insulated speaker cable according to the power handling ability of your GPL Series cabinet.
It is always advisable to use heavier gauge (lower number) cables on longer runs. Be sure to connect your speakers in
proper polarity (what many refer to erroneously, as phase). This means that in normal operation, connect one end of
terminal of the barrier strip
on the speaker. The other wire is connected to the –1 pin on the NL4 or the ‘–’ (negative) terminal on the barrier
strip.
