Description Product Description The QRx-112/75 is a two-way, full-range loudspeaker system that incorporates a 12-inch woofer and a 3-inch voice coil compression driver on an asymmetrical 75-degree x 50-degree fully rotatable constant-directivity horn. In factory-delivered position the horn provides a 15-degree up/35-degree down vertical coverage pattern. The five-sided cabinet design allows this main PA system cabinet to easily conform to duties as a floor monitor or to be tucked tightly against a ceiling for low-profile applications. The fully rotatable horn means that regardless of cabinet position, pattern control is fully user determined. The QRx-118S is a dedicated subwoofer loudspeaker system that incorporates the EVX-180B 4-inch voice coil driver for maximum LF reproduction power with minimum box volume. This vented, 600-watt system easily provides 131 dB SPL1 @1 w/1 m (137 dB peak1) at full power in a rectangular enclosure that is stable and readily stacks for extra energy or slides easily under even the lowest stages. The new switching power supply technology, completely designed from scratch and the consistent use of Class-H technology provide extensive headroom far above the stated nominal output and conspicuous reduction in leakage power at the same time. The employed switching power supply combines the headroom-advantage of a transformer power amplifier with low weight of a pulsed power supply unit resulting in an improved performance-to-weight ratio.
