The HALO Compact system is designed to fulfil requirements for a wide range of professional audio applications. At 17kg (37.4lbs) in weight and only 492mm wide (19.4”), HALO Compact is a truly compact solution but, as it is capable of continuous sound pressure levels in excess of 120dB, it is an ideal solution for small to medium theatres, houses of worship, conferences and corporate A/V, and even small to medium-scale live sound reinforcement. Any application where size and weight are critical concerns, yet high SPLs are required, is a perfect fit for the HALO Compact system. HALO Compact contains a 197mm (7.8”) AMT high frequency drive unit on an EM Acoustics-designed 95-degree dispersion waveguide. This HF device is linked via a signature EM Acoustics passive crossover to a high power neodymium 8” (203mm) LF drive unit. Exact drive unit placement, coupled with the crossover topology and waveguide design, extends the horizontal coverage pattern to below 1kHz. The true plane wave output of the AMT drive unit and waveguide combination yields a precise, well-behaved vertical pattern, allowing seamless array integration and minimising destructive interference between adjacent elements. The HALO Compact enclosure is constructed from premium 12mm and 18mm (1/2” & 3/4”) multi-laminate birch plywood that has been rebated, screwed and glued together. Intelligent bracing design minimises panel flexure, thereby reducing unwanted resonance whilst still keeping the enclosure weight low. The flying hardware is manufactured from ultra-high-tensile Domex steel, finished in a polyester powder coat with aircraft-grade ball lock pins to ensure swift, yet safe array assembly. A perforated steel grille backed with acoustically transparent black fabric finishes the enclosure with a sleek but stylish appearance. Two NLT4MP tour-grade connectors are provided on the rear of the enclosure for input and link through. The enclosure is finished in black or white semi-matt textured paint as standard. However, weather-protection options and custom RAL code colours are also available. For optimal results, either the DQ Series Advanced System Amplifiers, or the AQ or AD Series amplifiers combined with DSC48 processors should be used.
