Voltage Control Box calibration

When potentiometers are connected to the analog inputs of a Voltage Control Box, each analog input must be properly calibrated so that the volume is adjusted throughout the full range of the potentiometer's motion.  This article describes the calibration procedure for a Voltage Control Box.

Get connected

Once connected to the network, go to the Device Maintenance screen.  You can do this by clicking the "Device Maintenance" button in the System Connect window, or by going to the File menu --> Network --> Perform Audia/Nexia Device Maintenance.

In Device Maintenance, click the "RCB Devices" button.  Your Voltage Control Box(es) should appear in the RCB Devices window.  Select the Voltage Control Box that you're currently working on, and click the "Calibrate" button.

Calibration

Once the Channel has been selected, the next few screens will prompt you to set the potentiometer to its maximum and minimum positions.  At the end of the process, click "Finish" to complete the calibration.
