Mackie SRM150 Compact 150W Powered PA and Personal Monitor with 3-Ch Mixer

Mackie SRM150: Big Sound From a Mic-Stand-Mountable PA

The Mackie SRM150 is a compact powered PA and personal stage monitor that pairs a 150-watt Class-D amplifier with a 5.25-inch full-range neodymium driver and a built-in three-channel Mackie mixer, all in an enclosure small enough to thread onto a mic stand. It marries Mackie's proven mixer technology with the company's SRM speaker heritage to deliver high output and real fidelity from a box you can carry in one hand. For the performer who needs a full sound system that disappears into a backpack, it is proof that small can still fill a room.

150 Watts and a Neodymium Driver in One Hand

At the heart of the SRM150 is a 150-watt Class-D amplifier driving a premium 5.25-inch full-range neodymium transducer, a combination tuned for extremely high output and clarity relative to its size. The neodymium magnet keeps the driver light without sacrificing power, and the design reaches a usable 100 Hz to 17.5 kHz with up to 120 dB of maximum SPL at one meter - enough to serve as a personal monitor on a loud stage or a compact main for a small room. An integral aluminum heat sink keeps the amplifier running cool through long sets.

A Full Mackie Mixer Built In

Unlike a passive wedge, the SRM150 carries a complete three-channel Mackie mixer with the company's powerful 3-band active EQ for full tonal control of the output. Two Mackie mic/line preamps with switchable 48V phantom power handle dynamic or condenser microphones, an instrument-ready input takes a guitar or bass directly with no separate DI box, and a dedicated stereo channel brings in keyboards, a media player, or backing tracks. Everything mixes internally, so a singer-guitarist or presenter runs a whole show from one unit without a separate console.

Plug In Anything, Then Link and Expand

The SRM150 is built to grow with the gig. A combo line-in lets you link units or add more sources, while an XLR thru with a mic/line switch either chains additional SRM150s together or sends a direct feed to a larger main PA. That routing turns a single personal monitor into the front end of a scalable system: use one on a keyboard rig, add a second for stereo, or tap the thru output to drive the house. Complete system protection from a built-in limiter guards the driver no matter how hard you push it.

Built-Like-A-Tank and Ready to Travel

Mackie wrapped the SRM150 in a tough, impact-resistant polypropylene enclosure with a built-in top carry handle, so it shrugs off the knocks of load-in and stays easy to grab. The standout trick is its mic-stand integration system: the cabinet threads directly onto a standard stand or boom, putting a personal monitor right at ear level beside a vocalist, a drummer, or a lectern without eating floor space. It sets up in seconds and breaks down just as fast.

Who the SRM150 Is For

Solo performers, singer-songwriters, keyboard players, houses of worship, presenters, and mobile musicians who need clean amplified sound in a tiny footprint reach for the SRM150 as an all-in-one personal PA. Mount it on a stand as a monitor, set it on a table as a lectern speaker, or link a pair for a compact stereo rig - whenever the job calls for a real Mackie mixer and speaker in something you can carry with one hand, the SRM150 delivers.
