• 一句话简介：Clean QSC power and the reliability working musicians need.
• 简介：The PLX2502 power amplifier is an excellent choice for users who need to drive up to four loudspeakers from each amplifier channel (2-ohm loading), or when extremely high power bridged mono operation is required. Features built-in subwoofer processing, filter switches, and front panel indications of bridged mono status.
  
  The PLX2502 power amp has a solid, cast-aluminum front panel that adds professional style to any rack while also acting as an integral I-beam, rigidly tying the chassis together for years of on-the-road reliability.
  
  Additional mechanical touches such as the side stiffening rails, rear rack ears and cable tie anchor points attest to QSC's years of experience and attention to detail. QSC has even designed the integrated front handles so the amplifier slides into a rack without scraping your fingers on the rack sides.
  
  PowerLight Technology
  PowerLight switchmode technology replaces a large, heavy AC transformer (typically 20 lbs.) with a highly efficient and lighter-weight active design. Conventional AC transformers provide 100 or 120 energy pulses per second; the PowerLight supply delivers 190,000 to 230,000 pulses per second. More pulses make it easier to provide on-demand power for the amplifier's output section. The power supply doesn't sag so bass notes stay full and powerful while the high end remains crisp and clean.
  
  Audio Quality
  PLX2 audio power circuitry achieves performance normally associated with studio reference amplifiers. In order to reduce crossover distortion, precision bias tracking makes minute adjustments as amplifier temperature changes. The benefit is cleaner high-frequency and more consistent sound no matter how hard the amplifier is driven.
