Lend Me Your Ears
Exposure to extremely
high noise levels may cause
permanent hearing loss. Individuals vary considerably
in susceptibility to noise-
induced hearing loss, but nearly everyone
will lose some hearing if exposed to sufficiently intense noise for a period of time.
The U.S. Government’s Occupational
Safety and Health Administration (OSHA)
has specified the permissible noise level exposures shown in this chart.
Duration Per Day Sound Level dBA, Typical
In Hours Slow Response Example
8 90 Duo in small club
692
4 95 Subway Train
397
2 100 Very loud classical music
1.5 102
1 105 Patrice screaming at Ron about deadlines
0.5 110
0.25 or less 115 Loudest parts at a rock concert
According to OSHA, any exposure in excess of these permissible limits could result
in some hearing loss. To ensure against potentially dangerous exposure to high
sound-pressure levels, it is recommended
that all persons exposed to equipment capable of producing these levels use hearing
protectors while this unit is in operation.
Ear plugs or protectors in the ear canals or
over the ears must be worn when operating
this amplification system in order to prevent a permanent hearing loss if exposure is
in excess of the limits set forth here.
The SA1232
can produce a
maximum SPL of
136 dB @ 1m

INTRODUCTION
Thank you for choosing Mackie Designs’
active sound reinforcement speaker systems.
The SA1232 is a high-efficiency, extreme
output, active 3-way, wide dispersion,
sound reinforcement speaker system. The
SA1232 benefits from
the integration of 1300
watts of amplifier
power, complete active
control electronics, and
RCF Precision components. These elements
together form a

The SA1232 features the same horn
assembly we introduced in the Mackie
Designs SR1530 active
3-way speaker. The horn is a one piece design with 90º x 40º dispersion that
integrates both the mid-range and highfrequency sections. This provides seamless
coupling between the MF and HF sections.
The 6-inch mid-range’s basket assembly is designed as part of the horn assembly and is
also designed to function as an optimized
compression chamber, dramatically simplifying the mid-range assembly. The SA1232
features an “Optimized Wavefront” horn design. Unlike typical mid/high horns where
the mid- and high-frequency horns are
physically pointing to a different location in
front of the box, the SA1232’s high-frequency
section is positioned to fire down into the
six-inch mid-range’s dispersion pattern.
This creates a focused, single wave front
with excellent phase and power response
characteristics. With the resulting 90º x 40º
dispersion pattern, the SA1232 provides
very open, natural sound reproduction at
extreme output levels.
The SA1232 Mid/High Section is designed
to deliver over 136 dB of acoustic output.
In order to achieve this, the SA1232 incorporates several state of the art advancements in
transducer technology, which were developed
over a two year period. The compression
driver is a new 1.75-inch titanium diaphragm
design. It features a 3-slot, low-distortion
geometry phase plug.

The motor structure uses a high-grade
neodymium magnet providing extraordinarily high BL (gauss) and performance.

weight reduction, and
higher BL (force) in the

in better control of the

linearity.
MANUFACTURING DATE
The amplifiers for the
compression driver and
mid-range driver incorporate a Class AB topology
renowned for its clarity
and warmth, and for its
ability to produce the high-
voltage output required to generate extreme
SPL levels.
By using two 12-inch woofers, we provide a cone surface area larger than a single
18-inch device, yet we are able to move it by
an order of magnitude faster. This results in
an extremely tight, deep bottom end, while
efficiently reaching the mid-frequency
crossover point. The low-frequency amplifier features an innovative Class G hybrid
topology, which features two power supplies for improved efficiency that delivers
1100 watts rms (continuous), and 1400
watts peak at 100 Hz.
The rear mounted amplifier assembly
features separate signal and AC power panels separated by a large aluminum 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 system accepts a standard line-level
signal via an XLR input connector.
The SA1232 cabinet is constructed using
both multi-layered Baltic birch plywood and
pressure-injected structural resin caps. The
handles on each side are placed at the speaker’s
center of gravity for easy carrying and setup.
The top and bottom sections both have
handles for easy movement and relocation.
