System Requirements – Passive and Bi-amped Loudspeakers

The NuQ-6, NuQ-8, and NuQ-10 two-way loudspeakers are passive systems and require only one amplifier channel for correct operation, the frequency splitting between the LF driver and the HF driver being accomplished by the internal passive crossover network built into each enclosure. They are equipped with two Neutrik Speakon NL4MP connectors wired in parallel, serving as both input and loop-out connections to additional speakers. The Speakon wiring details are shown at the right. The NuQ-12 and NuQ-15 two-way loudspeakers are switchable passive/bi-amped systems and require two amplifier channels when used in bi-amped mode. To avoid wasting amplifier power you should use heavy-duty speaker cable with a minimum wire size of 12 gauge (1.5mm²), and preferably 10 gauge (2.5mm²) for longer runs. Always observe the correct polarity as shown.

Amplifier considerations

NuQ series speaker enclosures should be driven by high quality power amplifiers designed for true professional use. Amplifiers should be capable of delivering long term broadband power equal to the loudspeaker’s program power rating at its stated nominal impedance. The use of under-powered amplifiers must be avoided as heavily clipped signals can cause permanent loudspeaker damage.

RECOMMENDED AMPLIFIER POWER RATING

The amplifier’s rated r.m.s. continuous power output (20Hz – 20kHz, each channel)

should be equal to the loudspeaker’s program power handling at its nominal impedance.

System Controllers and Bi-amplified systems

NuQ systems must be used with Turbosound LMS-D24 or LMS-D26 controllers, since these provide vital operating and system security features. If you do not have a controller, DO NOT USE the loudspeaker without one; please contact your Turbosound dealer for further details.
