operation off of one connector, the bottom NL8
speakon connection is for four way operation off
of one connector.
d. Binding Post Output Jacks
One pair per channel of high-current, 60A
color-coded binding posts. Accepts banana
plugs, wire or spade lugs.
e. Power cord connector
32 amp PowerCon AC Inlet. Voltage range is

indicated above IEC inlet.
F. Reset Switch/circuit Breaker
If the current draw of the amplifier exceeds safe
limits, this breaker automatically disconnects
the power supply from the AC mains. The switch
resets the circuit breaker.
g. MAc Address
