13. Unplug this apparatus during lightning storms or when unused for long periods of time. 14. Do not connect a VHD2000 output in parallel or series with any other VHD2000’s output. Do not connect the VHD2000 output to any other voltage source, such as battery, mains source, or power supply, regardless of whether the VHD2000 is turned on or off. -

Page 5: Introduction, Warranty
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. -

GETTING STARTED 2.1 UNPACKING Unpack the VHD2000 and check to see if there is any damage to it. If you find any damage notify your supplier immediately. Only the consignee may institute a claim with the carrier for damage incurred during shipping. Be sure to save the carton and all packing materials for the carrier's inspection. -

Always isolate your AC supply before disconnecting the PowerCon connector. Your VHD2000 will be supplied pre set to the voltage used in your area. The table below provides typical current draw figures for the VHD2000. -

This is a dual colour LED, when green it indicates that the audio limiter has been activated. When red it indicates that the thermal limit of the VHD2000 has been exceeded and the unit has shut down because of this. - Page 9 VHD2.0 and both switches should be set to ‘Double’ . 8) Input Impedance This rotary switch sets the Input Impedance of the VHD2000 to match that of the mixer or other device supplying the audio signal to the VHD2000’s input. This is especially important when driving longer cable runs and it enables the line to be driven correctly without any losses or other interference.

2) Mid/High In / Pre Control Out This is an insert point for the Mid/High section of the VHD2000, the signal sent to the VHD2.0 cabinet. It enables you to ‘insert’ an external device (a delay line for example) into the signal that is being sent to the VHD2.0. -
Page 11: Normal Set Up
VHD2000 should be set to 50Ω. If when using the LD4 you are feeding more than one VHD2000 then they should all be set to 10kΩ with the last one in the signal chain set to 50Ω. Should you find that once the Input Impedance control has been set there is not enough input signal going into the VHD2000 (by looking at the Input metering) then there are two settings that give you +6dB extra gain on the input. -

4.2 FULL RANGE VOCAL MODE If the VHD2.0 is being used solely for vocal reinforcement & light music playback then the VHD2000 is used with the associated ‘Full Range Vocal’ switch depressed. A 60Hz roll-off is added to the system to protect the VHD2.0. - Page 13 MANUFACTURED IN THE EUROPEAN UNION MANUFACTURED IN THE EUROPEAN UNION VHD1.21 VHD1.21 The table below shows the various combinations of the Sub A/B switches and their effect on the signal routing in the VHD2000: Sub-A Switch Sub-B Switch Sub-A Out Signal Sub-B Out Signal...
