Self-powered Loudspeakers
The Class D amplifier modules fitted to the NuQ-8DP and NuQ-10DP self-powered
loudspeakers comprise one amplifier channel rated at 500 watts continuous, powering
both low frequency and high frequency drivers through a passive crossover network.
The Class D amplifier modules fitted to the NuQ-12DP and NuQ-15DP self-powered
loudspeakers comprise two amplifier channels rated at 800 watts continuous: one
channel to power the low frequency driver (LF) plus another channel to power the high
frequency (HF) driver; plus an active crossover to split the signal and feed it to the
appropriate amplifier and driver section. Additional features such as limiting, digital time
alignment and driver EQ are carried out in the on-board DSP.
The Class D amplifier modules fitted to the B15DP and B18DP self-powered subwoofers
use the two-channel amplifier bridged to provide 1600 watts continuous.
Self-powered NuQ series products do not require the use of external amplifiers or
crossover/limiters.
Additional units may be daisy-chained together simply by linking the signal connections
through the input / link XLR connectors. In this way exact coverage of an event or
permanent installation may be achieved using a number of digitally powered
loudspeakers. It is however necessary to route individual power cords to each enclosure
as it is not possible to daisy-chain AC connections through the power connectors.
