Harman Professional VLA Compact Series
The Variable Line Array (VLA) Compact Series is a line array loudspeaker solution. It is designed to fill the needs of system designers for installations requiring the long-throw capabilities of the VLA in a more compact line array solution. The modular design concept of the VLA Compact Series offers additional flexibility to vary the horizontal pattern within a vertical array by incorporating different modules with wider or narrower coverage patterns while still maintaining the vertical directivity.
The full-range speakers include dual 2261 10” Differential Drive 3” voice coil low frequency drivers, with 65° and 100° horizontal coverage options available. The VLA-C125S subwoofer has dual 2267H 15” Differential Drive woofers. Enclosures feature multi-layer reinforced fiberglass and steel end-panels. Grilles are zinc plated, powder coated 14-gauge perforated steel with acoustically transparent black grill cloth backing and a hydrophobic mesh underlayer, waterproof rail system.
Main Features (VLA-C2100) include:
• Line array module designed for permanent outdoor install applications
• Standard version featuring 3 HF drivers and 2 LF drivers featuring patented Differential Drive® technology
• Patent-pending horn design maintains very tight coverage pattern
• Mix and match coverage patterns with other VLA Compact Series line array modules
• Horn-loaded for great directional performance.
