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. -

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. -

If the VHD 2000 is connected improperly then this LED will light and the unit will shut down. An example of this is if a full range signal is applied to the 'Mid/Hi In' rather than the 'Main Input' , the VHD2000 will sense this and shut down to further protect any damage occurring to loudspeakers that are connected to it. -

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. With the associated switch in the 'Engage' setting the Pre Control Out connector would send the signal to the external device, and its output would be returned into the Mid/High In connector. -
Page 9: Using The System
KV2 Audio LD4 Line Driver then the Input Impedance control on the 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. - Page 10 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.
