Introduction
Voltage Control Box
The Voltage Control Box (VCB) is an external control
device, which provides four analog potentiometer
inputs and four logic inputs/outputs. When a VCB is
placed, an Initialization Properties dialog box appears
for assigning the quantities of logic inputs/outputs (4
total). Although the quantity of logic connections on a
Voltage Control Box (4) is different from those on a
Logic Box (20), their operation and behavior are
identical. (See
Logic Box for further explanation of
logic inputs/outputs).
Once a VCB block has been placed, double-clicking it will produce a dialog for assigning Analog
(potentiometer) controls.
A single VCB allows potentiometer adjustment of up to four selectable
Nexia levels. Levels can be individual or ganged levels within Nexia. This includes Level Control
blocks, as well as levels within other component blocks (such as Inputs & Outputs, Mixers ,
Equalizers , etc.). Object Code selects from a list of blocks found in the layout, and Instance ID is
entered automatically, but both can be found easily using Object ID Inspector . Control ID selects
from a list of available levels within the chosen block. Identifier provides a custom label for the
assigned control.
External controls must be identified (see Device Maintenance ) and associated with their
corresponding component blocks within the layout (see Equipment Table ). The VCB will assume
a full range of 0~5 Volts returning from connected potentiometers, unless the VCB Calibration
procedure is followed (see Device Maintenance ). Please refer to the 'Installation Guide'
(included with controls), or see Remote Control Bus for more information.
