The Mackie MCK-2042789-00 SRM350v3 is a high-definition, portable powered loudspeaker designed for professional musicians, DJs, and live sound engineers who require a versatile, high-output solution for a wide range of applications. This loudspeaker integrates a custom-designed 10-inch low-frequency driver and a 1.75-inch titanium compression high-frequency driver, each powered by its own dedicated Class-D amplifier within a total peak power system of 1000 watts. The SRM350v3 is engineered to deliver a powerful, full-range sound with exceptional clarity and extended bass response, making it suitable for use as a main PA speaker, a floor monitor, or a high-fidelity playback system for music and speech in venues such as clubs, houses of worship, and mobile events.

A key feature of the SRM350v3 is its comprehensive onboard digital signal processing (DSP) and mixing capabilities. The rear panel houses a flexible two-channel mixer with combination XLR/TRS inputs for microphones, instruments, or line-level sources, each with individual gain and 2-band EQ controls. Additional RCA inputs allow for easy connection of media players, and the mixer includes selectable DSP presets optimized for different applications, such as Main, Monitor, or Subwoofer modes. This allows users to tailor the speaker's response to its specific role in the system. The speaker's advanced waveguide ensures controlled 90° x 60° dispersion for even coverage, while its rugged, injection-molded polypropylene cabinet is built to withstand the physical demands of touring.

Designed for both portability and durability, the SRM350v3 includes integrated handles, a pole mount socket, and M10 threaded rigging points for versatile placement. Its efficient thermal management and protection circuitry ensure reliable performance even during extended, high-volume use. By combining powerful amplification, intelligent processing, robust construction, and flexible I/O, the Mackie SRM350v3 serves as a reliable and high-performance loudspeaker for professionals who need a single-cabinet solution capable of delivering clear, impactful sound in a variety of live sound scenarios.
