Surrey, UK (June 13, 2018)—EM Acoustics has debuted its new HALO Arena large-format line array system.
Following the same core design as the compact HALO-C line, the HALO-A has a 14.3 x 40.2 x 24.4-inch enclosure and weighs 145.2 lbs. The loudspeaker utilizes a proprietary patent-pending emulation manifold, setting four 3.4-inch diaphragm, 1.4-inch exit compressions drivers into a plane-wave array.
The HF section is flanked by a pair of 3.5-inch voice coil, 12-inch neodymium low frequency transducers.
A single HALO-A is said to offer a flat, free-field frequency response from 48 Hz to 19 kHz (+/-3 dB) and a phase response which is +/- 20 degrees between 150 Hz and 18 kHz.The dispersion pattern control is maintained down to 250Hz.
HALO-A requires two amplifier channels and makes use of the FIR DSP technology in the EM Acoustics DQ20 advanced system amplifier. The enclosure is constructed from 15 mm and 30 mm multi-laminate Baltic birch plywood and is finished in a weather-resistant polyurethane coating. Each box has a 3-point flying system, using steel parts coated with Zylan.
