Theory Professional is launching a new line of amplified loudspeaker controllers at InfoComm 2025. The PLC series, comprised of two 8-channel and two 4-channel models, leverages Powersoft’s patented Class-D amplification topologies, SmartRail energy-management power supplies, Power Factor Correction, and advanced DSP architecture to bring Theory’s premium sound into complex professional, large venue, and live sound applications.
“Theory’s small format products have received a very strong, positive reaction in the commercial market since being introduced at InfoComm in 2023. Integrators, specifiers, consultants, and end users have been asking us to bring Theory’s high-fidelity and high-output sound to their larger projects,” said Paul Hales, Theory CEO. “With our recently introduced SR Series loudspeakers and manifold subwoofers, paired with the new PLC loudspeaker controllers, we are going after that segment head on with a small catalog of immensely capable, innovative, and flexible products. If you’re a fan of the small format Theory products, wait until you hear what Theory can do for your live sound applications.”
Powersoft’s technology is widely recognized by the audio industry for its reliability, energy efficiency, and sonic transparency achieved through ultra-low noise converters, linear phase FIR filters, and Active Damping Control. Combining high-quality amplification with advanced DSP capabilities, plus PoE give PLC users exceptional sound reproduction and precise control. PLC 4 and 8 channel loudspeaker controllers are compact (only 1RU) but extremely power-dense. They are reliable, scalable, provide exceptional sound reproduction, and offer advanced DSP capabilities.
