The D.A.S. HQ-112.43 is a high-performance externally powered mid­high point source unit.

The HQ-112.43 system is intended as a flyable point source system
where very high sound pressure levels are in order, such as indoor or
outdoor sport venues, stadiums, arenas etc. It can be flown in the
same array in conjunction with other units as the HQ-112.64, HQ-

112.95 and the HQ-218.

The system comprises two frequency sections that are easily accessed
through NL-4 connectors or covered barrier strip terminals.

Mid frequency reproduction is handled by a 12HQ, 12” cone
loudspeaker coupled to a large horn and a phase plug combination.
This compression arrangement develops the high sensitivity and a polar
pattern control required for this type of systems. The 12HQ utilizes a
3” coil, massive magnetic structure specially designed to deliver high
efficiency in the speaker working range.

The transducer handling high frequency reproduction incorporates the

latest compression driver technology. The M-78N driver utilizes a
neodymium magnet structure, 1.5” exit and a 3” titanium diaphragm.
The compression driver has been specially designed to increase the
efficiency in the vocal range, between 1kHz and 8kHz. A dedicated
phase plug combined with the use of ferrofluid allows to obtain the
desired results.

The high-Q horns provide a precise coverage pattern and high SPL
over long distances.

The enclosure is manufactured from multi layer birch plywood and it
is finished as a standard version (CX) with black ISO-flex polyurea
paint. Totally exposed systems can be finished in fiber-glass. System
IP rating is IP-54.

The cabinet includes 20 x M10 rigging points that are intended to fix
stainless steel plates to create clusters.
