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.
