Lewis CaliburnTheory Audio Design will be introducing a new line of amplified loudspeaker controllers at CEDIA Expo 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 residential, professional, large venue and live sound applications.
“Theory’s DLC series of loudspeaker controllers are very popular in the residential segment. However, integrators, specifiers, consultants and end users have been asking us to bring Theory’s high-fidelity and high-output sound to their larger and more complex projects,” says 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 catalogue 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 large format projects.”
Powersoft’s technology is recognised 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 enhanced sound reproduction and precise control. PLC 4 and 8 channel loudspeaker controllers are compact (only 1RU) but extremely power dense. They are reliable, scalable and offer advanced DSP capabilities.
The four Theory PLC loudspeaker controller models:
PLC-4K8: 8 channels x 500W per channel
PLC-8K8: 8 channels x 1,000W per channel
PLC-9K4: 4 channels x 2,250W per channel
PLC-16K4: 4 channels x 4,000W per channel
“Partnering with Powersoft to create Theory’s PLC loudspeaker controller platform was a no-brainer,” says Marc Bertrand, Theory CSO. “Feedback directly from the field is that for large, complex installations, Powersoft’s patented amplification and processing technology delivers the best sounding, most powerful and reliable solution, especially for those deploying elaborate Dante or AES67 systems.”
“We are proud to embark on this close partnership with Theory, which places Powersoft’s patented amplification and DSP technologies at the heart of the new PLC line,” adds Luca Lastrucci, CEO of Powersoft. “Their decision to align with us validates our commitment to being the reference technology partner for power, efficiency and pristine audio in large-venue, live-sound and complex networked applications. Together, we will set a new benchmark for performance and reliability.”
Key features of Theory’s PLC Loudspeaker Controller platform include proprietary theory loudspeaker presets, native Dante & AES67 Audio over IP networking, all-channel power sharing, three configurable 1Gb network ports with 1x PoE, easy swap USB key amplifier restore and maritime compliance.
At CEDIA Expo 2025, Theory will show the PLC loudspeaker controllers in Booth 2933. The four models will be available in Q4 2025.
