Introduction
The VHD2000 is the amplifier control unit for processing and powering one VHD2.0 mid-high enclosure. It also houses all
processing and control electronics for the associated VHD subwoofer systems.
The VHD2000 is a three-way, rack-mounted unit containing high frequency, mid frequency and mid-bass amplifiers. The unit
features Class AB mosfet amplifiers for the high frequencies, with transformer-balanced outputs, and Class H mosfet amplifiers
for the mid frequencies. The midbass amplifier is a new version of KV2 Audio's high efficiency, analogue switch-mode amplifier
delivering 1600 Watts.
The VHD2000 is the world's first loudspeaker control system with proprietary digital signal delay technology using Super Digital
pulse density modulation components providing a 20 MHz sampling rate. The unit provides complete audio system control
including equalisation, overdrive protection, thermal protection and user adjustable set up parameters. Once the set-up process
is completed, the VHD 2000 manages all system functions and assures optimal performance.
The VHD2000 is "Line Driver Ready" and has its own input impedance selector on the front panel to accurately match up
the input impedance to the output of any mixer used. In most cases it would be advisable to use a VHD LD4 line driver in
addition at the mixer end to ensure that the line to the amplifier is driven correctly and the signal integrity maintained.
