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.
