Control Voltage
Control Voltage blocks allow analog potentiometers to adjust levels within a Tesira configuration file. Control Voltage blocks require supporting hardware to operate, such as an EX-LOGIC, IDH-1, OH-1, SNC-1 or TesiraFORTÉ.

| Channel Count | The number of logic inputs to be added |
| Equipment Type | Specifies what type of hardware the Compiler should allocate the block to. Review the Equipment Type section for more details |
DSP Block Representation
Control Dialog
| Name | Description |
Identifier |
Provides for a custom text label for the channel |
| Object Code / Instance Tag | Specifies the DSP object to be controlled. The text box will expand when selected and will give a list of available blocks found in the layout. If the Object Code is selected the Instance Tag is automatically entered. If the Instance Tag is selected the Object Code is automatically entered. The Object Code is assigned by the Tesira Compiler at compilation and is not user adjustable. The Instance Tag is User adjustable and must be unique. Control Voltage object code/instance tags will only display objects that are controllable within the same partition |
| Control ID | the channel number to be controlled |
Operation
Each channel in Control Voltage block represents a single analog potentiometer, and must be mapped to an existing level control in the Tesira configuration file. Control is not limited to Level Control blocks; any component block which supports level control can be adjusted, including Input blocks, Mixers, Equalizers, AV Inputs, etc.
External controls must be calibrated and associated with their corresponding component blocks within the layout (see Equipment Table ). The Control Voltage block will assume a full range of 0-5 Volts from connected potentiometers unless the VCB Calibration procedure is followed (see Device Maintenance).
