SRM150
The SRM150 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 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, 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.
APPLICATIONS
Small club/band PA systems, boardrooms,
A/V presentations, classrooms, personal monitor for
practice or performance, PA system expansion and many,
many more.
