The QD-9+ effortlessly drives high-power subwoofers, delivering flawless low-frequency performance, while simultaneously ensuring natural mid-range clarity and pristine high-frequency definition. Perfectly suited for integrating into line-array systems to drive mid- and high-frequency speakers, the QD-9+ is also an excellent choice for powering both low-frequency units and full-range speakers in stage-monitor setups.
Both models in the QD series share common family traits. At the heart of their design lies identical core technology, including the patented TD-class output-stage topology, a R.SMPS regulated switch-mode power supply, and a proprietary heat dissipation system featuring copper-fin radiators. Real-time monitoring and control are seamlessly integrated via the NomadLink network, with the network module included as standard equipment. No matter where your touring group may take you, after six years of rigorous research and testing, the QD series amplifiers stand out as exceptional products—boasting compact size, exceptional stability, lightweight construction, and powerful output—all of which make them ideal for both mobile performances and fixed installations.
