150W Portable Powered Loudspeaker
The SRM-150 combines Mackie’s proven mixer and SRM Series Active loudspeaker technologies to create a powerful, great-sounding 3-channel PA system that is ultra-compact, versatile and expandable. The Mackie SRM 150 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, just to name a few.

The built-in Mackie mixer provides two mic/line channels that accept XLR or ¼-inch connectors, with switchable 48V phantom power on the mic inputs. Channel 1 can also accept an instrument input directly from a guitar or bass with the press of a switch. A third stereo channel can be used for playing back MP3s, CDs, or tapes. A 3-band EQ is included to adjust the tone and minimize feedback, and a Thru connector provides a line-level output for connecting to a mixer or another powered loudspeaker.

The 5.25-inch full-range weather-resistant neodymium driver was specified by EAW to handle the 150 available watts delivered by the internal Class D amp. The SRM150 can deliver 120 dB SPL @ 1 meter, which is incredible for its size. The cabinet is constructed of high-pressure injected polypropylene. An insert is provided on the bottom of the cabinet for mounting on a mic stand, using the included mic stand adapter. In addition, a threaded insert is provided on the top of the cabinet for mounting a microphone, using the included mic boom extender.
