Loudspeaker connections
Passive systems
NuQ series passive loudspeakers are equipped with a recessed connector panel housing
two Neutrik Speakon NL4MP connectors wired in parallel and serving as both input and
loop out connections to additional NuQ series loudspeakers. The pin connections for the
NuQ-8 and NuQ-10—and the NuQ-12 and NuQ-15 when used in passive mode—adhere to
the standard professional audio loudspeaker wiring convention, which is pin 1+ positive
and pin1- negative as shown below. Pins 2+ and 2- are not connected.
