Product description is a passive column array loudspeaker with a complement of 7 3.5 (89 mm) LF transducers mounted in vertical array with an assembly of densely spaced 8 1 (25 mm) HF transducers mounted co-axially over a section of the LF (in an intuitively engineered, super-imposed chassis). VLS Series is the first range of products to incorporate FAST (Focussed Asymmetrical Shaping Technology), delivering unique acoustic performance benefits including asymmetrical vertical dispersion, gently shaping the coverage towards the lower quadrant of the vertical axis. packages this performance in a slender and narrow profile, aesthetically refined, powder-coated aluminium chassis with curved aluminium grille; ensuring a sleek and ultra-discrete appearance. Like the other 2 models in the range, can be ordered in either black or white as standard, with custom RAL colours available. The device is IP65 rated for dust and water ingress, salt spray and UV resistant and subject to rigourous high/low operational temperature and humidity testing making suitable for both indoor and outdoor use. Mounting is made easy via supplied flying and mounting brackets. Features 7 3.5 (89 mm) LF driver array FAST (Focussed Asymmetrical Shaping Technology) delivers improved intelligibility in typical listening plane and greater flexibility in mounting location Asymmetrical vertical dispersion: +6 degrees / -22 degrees (-8 degree bias) Highly consistent coverage pattern Peak output 12 db Sleek architecturally-sensitive profile Easy to install, mounting brackets included Easily accessible transformer tapping switch IP65 rated for water and dust ingress protection Available in black or white Integrated low insertion loss transformer for 1 V / 7 V operation Applications Houses of Worship Transportation hubs Retail spaces and concourses Conference rooms Lecture theatres Auditoria Gymnasiums Convention centers Museums Stadium concourses Multipurpose venues Challenging acoustic spaces Architecturally sensitive spaces Specification and design is aided by the use of Ease Focus v2. software, a generic, intuitive and easy to use three-dimensional acoustic simulation software. The software and relevant tutorials are free to download from the Tannoy website. features an integrated low insertion loss line transformer, configurable to various tappings via rotary switch, for use in high voltage distributed audio systems (1 V / 7 V).
