What is it?A multi-channel amplification system in a single, road-ready, plug-and-play rack, said to provide a versatile, turnkey solution for tour, rental, and installed sound applications.DetailsThe VRack 4x3500HD incorporates three of Crown’s flagship I-Tech 4x3500HD DriveCore Series four-channel power amplifiers, analogue and digital connections and a power distribution system that can be set to meet all international power standards. All components are housed in a wheeled rack with a captive suspension system that enables it to be flown in the same way as a line array speaker enclosure. The VRack 4x3500HD utilizes Harman HiQnet System Architect 3.2 control functionality and Version 5 DSP preset support for JBL Professional’s new VTX Series V25 plus VERTEC Series line array speakers with upcoming support planned for JBL VRX and STX models. System Architect provides control through monitoring and adjustment on a rack-by-rack basis and the ability to make changes to all three amps in the VRack through a single interface. The VRack 4x3500HD is also compatible with JBL HiQnet Performance Manager sound reinforcement system design software for enhanced control and monitoring capabilities.And another thing…Multiple VRacks can be linked together for integrated operation in larger systems.
