TH-12A

The Mackie TH-12A is a full-range, portable, powered

loudspeaker system providing high-output, ultra-wide

dispersion and low-distortion performance in a compact,

lightweight design. Two Fast Recovery™ ampliﬁers

independently power a 12-inch neodymium woofer and a

precision 1-inch compression driver. Mackie’s sophisticated

Active electronics provide phase correction, crossover, time

correction, equalization and protection circuitry.

Mackie-designed Active electronics provide a host of

processing designed to enhance the performance of the

TH-12A. Equalization, crossover, and time alignment

are working at all times to improve sonic performance.

Protective circuitry includes over-excursion protection,

thermal protection shutdown, auto reset, and driver

protection, including independent HF and LF compressors.

The TH-12A features a number of dedicated controls

including an EQ on/off switch, a 3-band EQ/contour section,

and a single microphone and line input level control.

The center of gravity, handle locations, handle design, and

ease of use have been ergonomically designed. There is also

an integrated pole mount cup and a weather-resistant steel

grille. The trapezoidal cabinet has been designed to provide

an ideal ﬂoor monitoring position.

The cabinet is constructed of high-pressure injected

polypropylene. The enclosure features reinforcement ribbing

and structural strengthening resulting in a strong, super-rigid

design providing ideal acoustical characteristics.

APPLICATIONS

Small club/band PA systems, houses of worship, DJs,

vocal/band monitor wedges, gymnasiums, banquet halls,

conference rooms and many, many more.
