JBL's VT4887ADP three-way line array element and VT4881ADP powered subwoofer are compact, powered models designed to deliver high-quality sound reinforcement of music and speech in a variety of applications, including concert audio, corporate A/V and theatrical presentations.

The VT4887ADP (pictured) houses two 8-inch woofers, four 4-inch midrange radiators and two 1-inch exit high-frequency drivers. Designed in cooperation with Crown and dbx, the JBL DP2 DrivePack features 2,200 watts peak (1,100W continuous) 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. The enclosure features foam-backed LF grilles, dense protective foam inserts for midrange apertures and a fine steel-mesh grille to protect HF apertures. Speaker cones are treated with weather-resistant compounds. Including all onboard electronics, system weight is only 87.5 pounds.

The VT4881ADP houses JBL’s new 2269G Ultra-Long-Excursion 460mm (18-inch) woofer and a JBL DrivePack DP1 fully integrated power and DSP electronics package. The DP1 provides 3,600W peak (1,800W continuous) output power. Including all onboard electronics, system weight is 137 pounds.

The VT4887ADP and VT4881ADP both feature rigging hardware that relies on quick-release pins and end-mounted metal frames to couple adjacent units together in rigid but flexible arrays. The VT4887ADP’s suspension hardware features quick-release pins and end-mounted metal tubes to couple adjacent VT4887ADPs together. The enclosure ships with an integral front and rear hinge bar set.

The VT4887ADP and VT4881ADP feature dbx input modules to implement crossovers, equalization, time alignment and protection for the attached speaker system. The standard DPIP input module features analog audio inputs and onboard digital signal processing technology. Precision bandpass limiting, pre-equalization filters and automatic self-test functions ensure optimized performance.

In addition to all of the features included on the standard input module, the optional DPAN (DrivePack Analog) module adds 100MB Ethernet networking functionality and HiQnet compatibility. Additionally, the optional DPCN (CobraNet™-compatible) input module offers the ability to direct up to 64 audio channels on one network, with digital audio and remote control and monitoring via Ethernet combined on a single cable.
