JBL’s VT4880ADP ultra-long-excursion, arrayable subwoofer.Northridge, CA (May 7, 2008)–Rounding out its VerTec Series line-array family of powered and passive loudspeaker models for the professional tour/rental and performance-venue markets, JBL Professional has introduced its VT4889ADP, a full-range, high-directivity, line-array element; and the companion VT4880ADP ultra-long-excursion, arrayable subwoofer.
Both models are integrated audio systems featuring JBL DrivePack technology. Co-developed with Harman Pro Group sister companies Crown International and dbx Professional, the DrivePack electronics modules with integral digital signal processing couple with VerTec loudspeakers.
The available DrivePack DP-3 module features Crown’s exclusive BCA (Balanced Current Amplification) technology, incorporating Class I circuitry with temperature-compensated modulation. Feedback circuits reportedly enable the DrivePack to offer lower noise and distortion specifications. The units include an auto-sensing Universal Power Supply and a fan-free, passive, cooling design. The 3-channel DP-3 offers a full-rated output power of 6,000 watts peak, 3,000 watts continuous (at load) for the VT4889ADP; and 6,900W peak, 3,500W continuous for the VT4880ADP subwoofer.
The standard input module from dbx features analog audio inputs, dbx’s Type IV analog-to-digital conversion circuitry and onboard digital signal processing technology. Precision bandpass limiting, pre-equalization filters and automatic self-test functions optimize performance. The modular input bay design allows for insertion of optional networked modules.
