The VT4888 is an articulating line array element designed for use in vertically oriented, multi-box systems. A nominal horizontal coverage pattern of 90° is maintained, while setting the individual box angles allows the creation of arrays with varying vertical coverage angles. Vertical coverage of an array is a function of the number of boxes used and the splay angles chosen. Up to 18 of the VT4888 enclosures can be suspended from the available VT4888-AF or VT4888-SF array frames with a 7:1 design factor. Due to the use of JBL’s S.A.F.E. suspension hardware system, rigid arrays can be constructed that can be tilted either upwards or downwards at radical angles. Front hinge bars are tightly coupled, while rear hinge bars are used to set angles from zero to ten degrees for adjacent enclosures. JBL VT4888 Features : - Advanced technology components: Differential Drive¨, neodymium magnet, dual voice coil, Direct Cooled cone transducers for low weight and high output.
- Direct Cooledª cone transducers for low weight and high output.
- HF Waveguide units couple to create precision vertical slot aperture.
- Radiation Boundary Integrator¨ (RBI): Patented technology integrates output of individual bandpass elements.
- Advanced construction techniques using PlyMax¨ provide exceptionally rigid, lightweight enclosure construction.
- Rugged DuraFlexª exterior finish; weatherized components.
- Patented, integrated S.A.F.E.ª suspension system: premium heat-treated alloys provide high-strength, reliable hanging arrays.
- Pre-engineered to accept optional JBL DrivePack¨ amplified electronics package. Rear-panel mechanical attachments and electrical connections ensure upgrade path to self-powered system.
- For use in stand-alone arrays or in combination with other VERTEC¨ system models.
