VHD2000
System Control and Amplification
The VHD2000 is the control and amplification unit for the VHD2.0. It is a three-way, rack-mounted unit containing high-frequency, mid-frequency, and mid-bass amplifiers. It also houses all processing and control electronics for the subwoofer system. Our own hybrid signal processing utilizes the very best technology available from both the analog and digital worlds to offer complete audio system control, equalization, overdrive protection, thermal protection, and user-adjustable setup parameters. Time alignment and phase correction are done via KV2’s new 20MHz digital delay line, boasting the highest sampling rate of any digital speaker processor available. Once the set-up process is completed, the VHD2000 manages all system functions and assures optimal performance.
Features
Three-way modular, 2900W Control and Amplification System for use specifically with VHD series modules
