Clean QSC power that runs quiet and cool.

The PLX1802 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 PLX1802 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.

Professional lightweight amp

I bought this about 18 mos ago. I use it to drive up to three x 350W (prog)/ 700W (peak) 12" cabs. Sound reproduction is very clear & accurate. It's also lightweight & runs cool.

I marked down quality only because the faceplate is cast aluminum. Under normal use, this is fine. But, I broke a rack ear off when the amp (in the rack) accidentally fell off my truck. (I was able to buy another faceplate from QSC tech support).

Other than that, awesome amp. I use it several times/week & haven't had even the slightest glitch in function. I just purchased my second amp - it was another PLX2 series.
