INTRODUCTION
A male XLR Thru jack is provided for daisy-chaining the
signal to additional SA1232z cabinets.
Three built-in power ampliers provide 100 watts rms
each for the mid-frequency and high-frequency drivers,
and 1100 watts rms for the low-frequency driver. The
amplier modules sit on a mammoth aluminum heatsink
that eliminates the need for fans. A tremendous benet
of having the ampliers located within the loudspeaker
cabinet is that the SA1232z functions as a system, opti-
mizing acoustic, electronic, and mechanical designs to
achieve the highest level of performance and value.
The rear mounted amplier 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.
Thank you for choosing Mackie’s active sound reinforce-
ment loudspeaker systems.
The SA1232z is a high-efciency, 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 re 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 12-inch
woofers.
Connecting and setting up the SA1232z is a breeze. It
accepts a line-level signal via a female XLR input jack.
