INTRODUCTION

Thank you for choosing Mackie's active sound reinforce-
ment loudspeaker systems.
The SA1532z is a high-efficiency, extreme output,
horn-loaded, 3-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 3000 Hz, eliminating the place-
ment of a crossover point in the middle of critical voice
frequencies. Frequencies above 3000 Hz are reproduced
by a 1.75-inch neodymium compression driver. The low
frequencies are produced by two high-output 15-inch
woofers.
Connecting and setting up the SA1532z 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 SA1532z cabinets.
Three built-in power amplifiers provide 100 watts rms
each for the mid-frequency and high-frequency drivers,
and 1100 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 SA1532z 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
separate signal and AC power panels separated by the
heatsink. The signal input panel contains:
• an input XLR and loop-through XLR
• a volume level control
• Power ON indicator
• Signal Present indicator
• Limit indicator
• Thermal 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.
