Overview: The Mackie Thump12A is a portable powered loudspeaker,
designed for DJs and live performances; featuring a durable, lightweight molded enclosure, a rugged powder coated steel grill, and two full-grip side handles, plus top and bottom lift pockets. The
2-way speaker design is comprised of a 12" low frequency driver and a 1.4"
titanium dome compression driver, with up to 1300 Watts peak power available. A
built-in 2 channel mixer, with level adjustments for each input, can handle both
mic and line inputs and includes an XLR pass-through to daisy-chain multiple
speakers. Other useful features include a 4-positon Speaker Mode
switch, which provides four preset Eq curves, and a built-in limiting circuit to
help protect the speaker from distortion and over-excursion of the drivers.
Inputs/Outputs: The Thump12A has two input jacks that can accommodate
either balanced XLR's or unbalanced 1/4" TRS connections. A balanced XLR Mix out
jack is provided to send the mixed signal, of inputs 1 and 2, out to another
amp/amplified speaker. Both inputs have their own rotary gain control, that can
accept a wide range of signal levels, and include marked settings for both Line
and Mic inputs. A Main level control adjusts the overall volume.
Speaker Modes: Four Speaker Modes are available to tailor the sound for the room or application.
Music: This is a full range Eq curve with boosted levels in the
high and low frequency ranges.
Live: This mode features a low frequency roll-off, to get rid of
unwanted thumps, and adds boost to mid-range and high frequencies.
Monitor: This setting has low frequency roll-off and a reduction
around 2 kHz to ensure maximum gain before feedback when using the speaker
as a monitor.
Sub: This mode rolls off the low end to the Thump12A drivers, but
still outputs low frequencies from the Mix Out jack to run to a subwoofer.
Power: Total output power is 1300 Watts divided between the two driver amps,
with the low frequency amp providing up
to 1000 Watts to the woofer and the high frequency amp providing up to 300 Watts
to the tweeter.
Placement: The Thump12A's flexible design allows it to sit upright or on its side at
a 45˚ angle, as a stage monitor. It also includes a built-in
socket on the bottom of the cabinet allowing the speaker to be pole/tripod
mounted. When sitting upright, the speaker provides a coverage angle of 90˚ horizontally
and 60˚ vertically.
Note: These speakers are not designed for rigging or
"flying" and have no rigging points installed.
Protection Circuitry: All of the Thump line loudspeakers include
various protection features. These include; a dynamic bass response circuit,
which provides optimal low frequency response regardless of overall output
level, a limiting circuit to protect it from damaging transient signal peaks,
and a sub-sonic filter, prior to the amplifier, that prevents ultra-low
frequencies from being amplified. An LED on the rear panel will light when
limiting takes place.
