Part of QSC's PLX Series, the QSC PLX3602 power amp is a premium-quality, high-power amplifier designed for the most demanding live performance uses. Built on the third generation of QSC Power Light technology, the PLX3602 amplifier combines light weight, superlative audio quality and proven QSC reliability. The PLX3602 is the right choice for users who need to drive up to four loudspeakers from each amplifier channel (2 ohm loading), or when extremely high power bridge mono operation is required. This models features built-in subwoofer processing, filter switches, and front panel indications of bridge mono status. The audio power circuitry inside the PLX3602 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. The higher power models use QSC-exclusive class H output circuitry, a form of audio "turbocharging" that increases maximum power without affecting the basic audio quality.
