The SRM150 combines Mackie's proven mixer and SRM Active loudspeaker technologies to create a powerful, great-sounding 3-channel PA system that is ultra-compact, versatile and expandable. The Mackie SRM150 Compact Active PA System is ideal for a wide variety of applications ranging from boardroom A/V to live musical performance in coffee houses, piano bars, or rehearsals, or for use as an onstage monitor, to name a few.

Don't be fooled by its small size; the SRM150 is big on features and sound quality. The built-in three-channel mixer features two combo XLR/line inputs (with switchable true 48V phantom power for XLR), a stereo channel for CD/MP3 players, and Mackie's powerful 3-band Active EQ. The first channel also has a Hi-Z switch so you can connect your guitar, bass, or other instrument-level signal directly into the mixer. The SRM150 can even be mounted on a mic stand, making it the ideal personal monitor. Put simply, with its tremendous feature set and 150-watts of world-class sound, the Mackie SRM150 is the perfect solution for many applications - even PA system expansions for "Cry" or "Green" rooms.

All the "bells and whistles" in the world are completely worthless if you can't crank the sound. That's why Mackie matched the SRM150's powerful 150-Watt Class-D amplifier with an impressive 5.25" full range, weather-resistant neodymium driver, which was developed by the tried-and-true EAW. The SRM150 puts out a blistering 120dB SPL @ 1 meter, far more than the competition offers.

Not only is the SRM150 an excellent loudspeaker system for compact PA applications, but it also offers unparalleled performance as a personal monitor. The onboard 3-band EQ facilitates feedback suppression and offers the same great tone-shaping capabilities as their legendary compact mixers. Mic stand ready with an included boom arm adapter, the SRM150 puts total control right at your fingertips. In addition to stand mounting, the SRM150 was designed to provide the proper monitoring angle when used in traditional floor wedge and tabletop placement.
