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

  • High Frequency, 300W, Class AB, push-pull low intermodulation amplifier with transformer-balanced outputs

  • Mid Frequency, 1000W, high efficiency, wide power bandwidth amplifier

  • Mid Bass, 1600W, high efficiency, current enhancing switching amplifier

  • The setup provides two channel selection and control of different VHD subwoofer combinations, or full range mode, with level control +/- 6dB and two rear-mounted line-level subwoofer outputs to feed a VHD 3200 subwoofer amplifier

  • Complete onboard speaker management system, including equalization, time alignment, crossover filters, amplifier overdrive protection, system set-up, and output level controls

  • Newly developed PDM 20MHz sampling, digital delay alignment system sets new standards for audio performance and dramatically increasing phase response precision and definition

  • AC soft-start circuitry with ON/OFF AC breaker switch provides thorough power protection

  • Comprehensive front-to-back cooling system features chassis sealed pcb’s for improved reliability

  • Two per side switch engages a specific set of filters and operating parameters for larger scale events when using an extra VHD2000 and VHD2.0 per side

  • Individual signal inserts for Mid/High, Subwoofer A, and Subwoofer B providing flexibility for insertion of signal processing or feeding from auxiliary sources as required

  • Front panel Input Impedance selector provides a selection of optimal input impedance when used with a KV2 Audio LD4 Line Driver
