[. . . ] PLX2 Series ProfessionalPowerAmplifiers PLX1104 | PLX1804 | PLX1802 | PLX2502 | PLX3102 | PLX3602 The PLX2 Series is a range of premium quality, highpower amplifiers designed for the most demanding live performance uses. [. . . ] PLX2 Series amplifiers have the refined but rugged good looks of professional power tools and high power machinery. A solid, cast-aluminum front panel adds style to any rack while acting as an integral I-beam, rigidly tying the chassis together for years of on-the-road reliability. The PLX2 Series now includes two approaches to meet a wider range of needs and budgets. The fully featured "02" models (1802, 2502, 3102, 3602) drive 2 ohm loads and add subwoofer processing and convenient rear-panel signal processing control switches to the original, still unmatched PLX platform. In addition, the compact "04" models (1104, 1804) have been added to bring the same performance and technology, plus even greater value, to applications that don't require bridged or 2 ohm operation.
