Description

Details

The VT4887ADP Powered Compact Bi-amplified 3-Way High Directivity Line Array Element. Array Element is designed to deliver high-quality reinforcement of music and speech in a variety of applications including concert audio, corporate A/V and theatrical presentations of all types for both portable users and performance venues.

The VT4887ADP is a compact, powered lightweight 3-Way Line Array Element housing two 8" woofers, four 4" midrange radiators, and two 1" exit high frequency drivers. Designed in cooperation with Crown and dbx, the JBL DP2 DrivePack features 2200 watts peak output power and comprehensive digital signal processing, including patented high efficiency “Class-I” power amplifier technology from Crown and onboard DSP functionality that communicates readiness and operational status and monitors fault detection of components and electronics. Advanced VERTEC-class component transducers provide a high power-to-weight ratio. Enclosure features foam-backed low frequency grilles, dense protective foam inserts for midrange apertures, and fine steel mesh grille to protect high-frequency apertures. Speaker cones are treated with weather-resistant compounds. The VT4887ADP’s suspension hardware relies on quick-release pins and end-mounted metal tubes to couple adjacent VT4887ADP’s together. Enclosure ships with integral front and rear hinge bar set.
