Unpacking the Loudspeaker
After unpacking the unit please check carefully for damage. If damage is found, please notify your supplier at once. You,
the consignee, must instigate any claim. Please retain all packaging in case of future re-shipment.
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.

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.
