About Williams Sound SoundPlus T3

The SoundPlus T3 continues Williams AV's legacy of audio innovation. Featuring cutting-edge LED technology, it delivers a stronger, more consistent audio signal over a wider range than previous models, ensuring comprehensive coverage and minimizing dropouts.

The new LEDs offer increased power and efficiency, providing complete coverage of up to 32,000sq ft (2,972sq m), overcoming background noise, reverberations, and distance from the sound source. With its expanded coverage pattern and more robust audio signal, there's no need for the additional cost of a secondary unit.

Engineered for AV professionals, the T3 offers a two-channel infrared transmitter with an integrated modulator and emitter. It operates on switchable carrier frequencies and includes optional Power-over-Ethernet (PoE) capability, allowing remote power delivery up to 100 feet, and remote RS-232 commands provide convenient control.

The T3's compact form factor allows for discreet placement, ensuring it integrates seamlessly into any room's aesthetics. It accommodates adjacent rooms without signal spillover, maintaining clear, high-quality audio within a single space. Ideal for environments requiring privacy or confidentiality, such as corporate boardrooms or spaces with sensitive information.
