6) Sub A & B Set Up
These switches are set according to which combination of subwoofers is being used with the
system - see Operation Modes.
7) System Single / Double
This switch sets the controller for use when either a single VHD2.0 is being used or a double
system using 2 VHD2.0’s are being used. In this mode another VHD2000 would be required to
power the second 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. Ideally an LD4 line driver should be used. See Using the System.
9) Tilt
This switch when depressed electronically ‘tilts’ the dispersion of the VHD2.0 down vertically by
10°. The Tilt switch should only be used when a single VHD2.0 system is being used.
10) Master Level
This is the master level control for the system and will affect both the VHD2.0 and the subwoofer
outputs.
11) Sub A / B Level
These are the level controls for the Sub A and B outputs; they are ‘post’ the Master Level control
12) Full Range Vocal
When this switch is activated it enables the VHD2.0 to be used as a full range system without the
need for subwoofers, ideally suited to vocal reproduction and light music applications. The
VHD2.0 will run full range with a 60Hz roll-off added to the system for protection. Note in this
mode the subwoofer outputs will be muted to prevent incorrect use of the system.
