Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Powered PA Loudspeaker: The Mackie TH-12A is a full-range, portable,
powered loudspeaker providing high-output, ultra-wide dispersion and
low-distortion performance in a compact, lightweight design. An ultra-wide
frequency response makes them ideal as a keyboard, vocal, or even bass guitar
400W Ultra-Efficient Fast Recovery Amplification: Class-D Fast
Recovery amplification pushes unmatched power to the high-frequency compression
driver and bass-pounding high-output woofer. Two Fast Recovery amplifiers
independently power the 12" low-frequency woofer and 1" high-frequency
High-Output Transducers: The Mackie TH-12A houses a 1" high-frequency
compression driver for smooth, wide dispersion, and a 12" low-frequency woofer
for chest-pounding bass.
Mackie Active Processing: Mackie Active processing, including a
precision crossover and driver time-alignment provides total optimization for
maximum system efficiency.
- Electronic Crossover: Featuring separate Linkwitz-Reilly
24dB-per-octave crossover circuits for the LF woofer and HF compression
driver, Mackie's electronic crossover circuitry effectively splits input
signal frequencies into highs and lows for the transducers, and eliminates
unwanted phasing issues. As a result, you get optimum imaging, depth of
field and definition.
- Time Correction: Time Correction technology effectively times the
arrival of electrical impulses to each transducer, to ensure both highs and
lows arrive at the listeners' ears simultaneously.
3-Band Contour EQ: A 3-band equalizer gives you tonal control, with an
available 15dB boost or cut at 80Hz (low shelf), 100Hz to 8kHz (sweepable mids),
and 12kHz (high shelf).
Mic/Line Input/Output: The Mackie TH-12A is fitted with a Mic/Line
XLR balanced input for direct connection of a microphone or
mixer output. There is also a XLR balanced output to daisy chain another Mackie
TH-12A powered speaker.
Impact-Resistance Enclosure: The cabinet is constructed of
high-pressure injected polypropylene. The enclosure features reinforcement
ribbing and structural strengthening resulting in a strong, super-rigid design
provide ideal acoustical characteristics.
Portable Design: The ultra-lightweight and ergonomically-minded
cabinet design means easy setup and transport.
Mounting Options: There is an integrated pole mount cup for use with
an optional pole mount system (sold separately). The trapezoidal cabinet has
also been designed to provide an ideal floor monitor position.
Protection Circuitry: Each driver has its own transparent compression
circuit, which helps protect them from damaging transient peaks. An
over-excursion filter, inserted just before the low frequency amplifier,
protects the woofer from bottoming-out when the low-end is driven to the
maximum. Separate thermal switches activate and shut down the high and/or low
frequency amplifiers until they cool down. These safeguards ensure long life and
great-sounding loudspeakers you can always count on.
