Overview:

The Model 1400 is designed for professional and commercial audio applications requiring both high performance and high reliability. The result of careful research, the 1400 is loaded with useful features and benefits.

QSC’s PM Series power modules are the most compact, lightweight and efficient loudspeaker power modules currently available. They have been specifically developed to meet the headroom and voltage swing requirements of high-end professional loudspeaker systems. The PM1400 delivers 1400 watts into a single channel.

The linear amplifier technology utilized in most current powered loudspeaker designs is capable of acceptable audio performance, but inherent inefficiencies limit the maximum power of these systems to the 300 – 500 watt range. Multi-tier linear technology can extend this to as much as 700 watts (as in QSC’s HPR speakers), but still requires a large, heavy heat sink.

Existing amplifier technologies forced compromises upon the loudspeaker designer that QSC engineers found unacceptable. The resulting specification called for an amplifier package measuring no more than 4.4″ x 14.6″ x 7″ (112 mm x 371 mm x 178 mm) and weighing only 8 lb (3.6 kg) yet capable of continuously delivering double or triple the amount of power traditionally feasible in a package of this size. Our engineers combined the lessons QSC has learned from three generations of PowerLight™ technology power supplies with a unique approach to Class D amplification to create the PM Series power modules.

Until now available Class D solutions have been constrained by voltage limitations, and thus remained below the 500 watt (at 8 ohms) barrier, and many designs have also suffered from imperfect audio quality. QSC has broken through these barriers, with ratings exceeding 800 watts into standard 8 ohm loads, and 1400 watts into 4 ohms. Peak voltages can reach 120 volts, at up to 30 amps of current (3600 watts of “peak power”). At the same time, advanced internal error-correction keeps audio quality pristine across the entire frequency range. QSC has finally opened the door to combining the horsepower potential of Class D with no compromise audio performance.
