Main Features

  • Provides 20 logic connections
  • Programmable in any combination as logic inputs and logic outputs
  • Presets, mutes, ducking, combining through external contact closures
  • Logic outputs provide control of external circuitry
  • Indicator panels, speaker relays, camera presets through open collector transistors
  • Allows system control of external support equipment


Logic Box is a natural extension of Audia® and Nexia® products. This device provides both logic inputs and outputs, as a programmable control interface. Logic inputs allow creation of custom control panels, with completely programmable functions.  Logic outputs allow the system to provide programmable triggers to external circuits, such as status indicators and speaker relays. Innovative design allows 20 available connections on the Logic Box to be configured in any combination of inputs and outputs. This extends true flexibility for a variety of applications, using the same hardware. The Logic 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 Logic Boxes, and Control Panels, can be connected on one bus, over a large physical distance.

Product Features

  • 20 logic connections - any combination of inputs/outputs
  • Logic inputs - control system actions from external switches
  • Actions are any individual or grouped system operation 
  • Actions include presets, mutes, ducking, combining, etc.
  • Logic outputs - trigger external control circuits from system  
  • External circuits can be indicators, speaker relays, etc.
  • Logic functions programmed within system software design
  • Logic functions can be made to change along with presets
  • Various Audia/Nexia controls allowed on same system bus
  • 1000' cable length per Audia/Nexia device control bus
  • Convenient key-hole mounting (local power not required)
