Main Features

  • Allows creation of custom control panels
  • Completely programmable functions
  • Provides 4 analog potentiometer inputs, plus 4 logic connections
  • Logic inputs provide control of system actions
  • Logic outputs provide control of external circuitry
  • Allows system control of external support equipment


Voltage Control Box is a natural extension of Audia® and Nexia® products. It provides four inputs for analog potentiometers plus four logic input/output connections, as a programmable control interface. Voltage Control Box allows creation of custom control panels, with completely programmable functions. Potentiometers may be assigned to control various system levels. Logic connections may be assigned individually as either inputs or outputs, for switch control of internal functions such as preset selection or for triggering external circuits such as status indicators. The Voltage Control Box is connected to a system on a 5-wire daisy-chain, eliminating the need for local power sources. This connection also provides the serial communication to the Audia or Nexia system. Multiple Voltage Control Boxes, as well as other Audia/Nexia controls, can be connected on a single bus, over a large physical distance.
