| VHD2000 System Control and Amplification |
|
|
The VHD 2000 is the control and amplification unit for the VHD 2.0. 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 brings together the very best technology available from both the analogue and digital worlds to offer complete audio system control, equalization, 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 VHD 2000 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.
Additional features include a Full Range setting for running a VHD 2.0 down to 60Hz, useful for many speech and playback applications where subwoofers are not needed, and an electronic ‘Tilt’ function which will electronically tilt the VHD 2.0 Mid high cabinet down by 10°. This is particularly useful where the physical placement of the boxes is restricted relative to the intended area of coverage. |
