VHD2000 · Using the system
Normal Set up
The VHD2000 is designed to actively power one VHD2.0 cabinet and to provide signal processing for associated subwoofer
systems when used. For Normal Mode operation signal is applied to the 'Main Input' connector and all the 'Insert' switches
would be in the 'Disengage' position.
The Input Impedance control should be set to match the output impedance of the device feeding the VHD2000. If you are
using a 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. 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.
Six different combinations of sub woofers are accommodated for when using the VHD2000. The associated 'Sub-A Set Up'
and 'Sub-B Set Up' switches are set according to which combination is being utilised on the Sub-A and Sub-B outputs. Both
switches must be set to the same setting. These outputs are then fed from the 'Sub-A Out' and 'Sub-B Out' connectors into
VHD3200 amplifiers that power the subwoofers themselves. The six different combinations are as follows:
Amplifier / Controller Setting Sub-A Out Sub-B Out
Setting 1 2 x VHD2.16 (1x2.15) 2 x VHD2.16 (1x2.15)
Setting 1B 2 x VHD2.16 (1x2.15) 1 x VHD2.21
Setting 2 2 x VHD4.18 2 x VHD4.18
Setting 3 2 x VHD2.16 (1x2.15) 2 x VHD1.21
Setting 4 2 x VHD2.16 (1x2.15) 2 x VHD4.18
Setting 5 (Double System) 4 x VHD2.16 (2x2.15) 4 x VHD4.18
Setting 6 (Double System) 4 x VHD2.16 (2x2.15) 4 x VHD1.21
Settings 5&6 require 2 x VHD3200 amps
