Costa Mesa, CA (May 24, 2006)--Offering more power and enhanced performance, QSC's MD Series self-powered loudspeakers are now shipping. Suited for a wide variety of applications ranging from houses of worship to hotels, casinos, nightclubs and sports facilities, the product group is a family of modular, arrayable enclosures including full-range models MD-FP122/64r, MD-FP122/94r, MD-FP152/64r and MD-FP152/94r.

Offering various coverage patterns employing 12- or 15-inch low-frequency drivers, the new full-range, self-powered MD models all share the same 35-inch-tall trapezoidal enclosure as QSC's passive MD Series. Given the identical dimensions of the cabinets, the task of creating full-range or combined full-range/low-frequency clusters becomes an easy task. Designed with 30-degree angles, the self-powered MD Series enclosures can additionally be tightly packed in a fashion optimally splaying their 60x40-degree horns to insure uniform coverage in any multiple of 60 to 360 degrees. No gaps or spacers are required, and the radial front grilles form a contiguous cylindrical surface, giving any self-powered MD array a clean and eye-pleasing appearance.

Central to obtaining QSC's more-with-less goal of turning up the wattage on tap within the self-powered MD Series without adding extra weight and bulk is the PM-1000 amplifier module. Weighing little more than a passive crossover network yet capable of delivering the performance of a rackmount amplifier, the PM-1000 was developed concurrently with the PM-1400 amplifier module.

The modules are the first examples of QSC's singular approach to Class D amplifier technology. Drawing upon invaluable lessons learned over the course of developing three different generations of lightweight switch-mode power supplies, QSC designed the PM-1000 expressly for use with 2-way systems, while the PM-1400 is ideally suited for subwoofer applications. Employing dual-switching circuitry, the PM-1000 offers 800 watts at lower frequencies, while 200 watts of power is kept at hand to insure stellar performance beyond 20 kHz. Conversely, the PM-1400 uses only an LF channel, making it capable of delivering more than 1,400 watts into a 4-ohm load.
