INTRODUCTION
Connecting and setting up the SR150z is a breeze. It
accepts a line-level signal via a female XLR input jack.
A male XLR Thru jack is provided for daisy-chaining the
signal to additional SR150z cabinets.
Three built-in power amplifiers provide 100 watts rms
each for the mid-frequency and high-frequency driv-
ers, and 00 watts rms for the low-frequency driver. The
amplifier modules sit on a mammoth aluminum heatsink
that eliminates the need for fans. A tremendous benefit
of having the amplifiers located within the loudspeaker
cabinet is that the SR150z functions as a system, opti-
mizing acoustic, electronic, and mechanical designs to
achieve the highest level of performance and value.
The rear mounted amplifier assembly features:
• an input XLR and loop-through XLR
• Power ON indicator
• Protection indicator
The cabinet is constructed using both 18 mm multi-
layered plywood and pressure injected structural resin.
A carrying handle is integrated into each side for easy
loading and transport.
Thank you for choosing Mackie’s active sound reinforce-
ment loudspeaker systems.
The SR150z is a high-efficiency, extreme output,
horn-loaded, -way, wide-dispersion, active sound
reinforcement system. It features a one-piece 90º x 40º
horn, which includes both the mid- and high-frequency
sections in a proprietary optimized Wavefront™ design.
Unlike typical mid/high horn designs, the high-frequency
section is positioned to fire down into the 6-inch mid-
range’s dispersion pattern. This creates a focused, single
wave front with excellent phase and power response
characteristics. The resulting 90º x 40º dispersion pat-
tern provides a very open, natural sound at extreme
output levels.
The 6-inch neodymium mid-range transducer oper-
ates between 700 Hz and 000 Hz, eliminating the place-
ment of a crossover point in the middle of critical voice
frequencies. Frequencies above 000 Hz are reproduced
by a 1-inch neodymium compression driver. The low fre-
quencies are produced by a high-output 15-inch woofer
with a X-inch high-temperature voice coil.
