PMC MB3S-A-C

PMC MB3S-A-C — active 3-way centre channel monitor with ATL™ technology, a frequency response from 20 Hz to 25 kHz, and a total amplifier power of 3225 W. Equipped with a 12-inch Radial™ bass driver, this model is designed for high-end multi-channel monitoring setups in post-production, film, broadcast, and mastering studios.

The MB3S-A-C is a low-profile centre monitor specifically designed to integrate seamlessly with the MB3S-A or MB3 XBD-A systems. Its Advanced Transmission Line (ATL™) design ensures deep, tight, and accurate low-end extension down to 20 Hz without additional subwoofers. Capable of delivering up to 126 dB SPL without distortion or fatigue, the MB3S-A-C excels in demanding environments where clarity, dynamics, and long listening sessions are critical.

Each frequency band is powered by dedicated Class-D amplifiers: 1200 W for low frequencies, 550 W for mids, and 275 W for highs. Input is handled via AES3 digital connection at 24-bit/96 kHz resolution, with full compatibility for modern digital workflows. Its wide frequency range allows it to function independently of subwoofers, with optional LFE input supported through the Control 1200 unit, making it an ideal choice for immersive and surround audio formats.
