Active 3-Way Sound
Reinforcement Speaker System
The SA1232 is a high-efficiency, extreme-output,
active 3-way, wide dispersion, sound reinforcement
speaker system. The SA1232 benefits from the inte-
gration of 1300 watts of amplifier power, complete
active control electronics, and precision components
into a speaker system with 103 dB of sensitivity (1 watt/
1 meter). The result is unprecedented output, resolu-
tion, and clarity as well as mid-range reproduction
previously available only from high end, esoteric PA
speaker systems.
The SA1232 features the same horn assembly as
introduced in the Mackie SR1530 active 3-way speaker.
The horn is a one-piece design with 90° x 40° disper-
sion that integrates both the mid-range and high-

frequency sections. This allows for the horn loading
of the mid-range transducer and seamless coupling
