For the receiving end of long control runs we recommend the DMX512 Isolation Amplifier. It contains separate input and output power supplies. This allows the input circuitry to receive signals as low as 0.2 volts. These are optionally available in any number of configurations for systems with more than one DMX512 universe. Input and output circuitry and specifications are identical to that of our standard splitters.


  • Input circuit: EIA-485 receiver with 120 ohm Termination resistor between +Data and -Data (Units with optional feed through connectors do not have internal termination)
  • Input signal: 0.2 volts minimum, 12 volts maximum
  • Output circuit: EIA-485 driver
  • Connectors: Gold plated 5 pin Neutrik D-1 Series
  • Feed through: A non-isolated feed through connector is optional
  • Isolation: 2500 volt optical coupler, 1500 volt split bobbin transformer
  • Power input: 100 - 120 volts, 50/60 hertz, 12 watts (208 - 240 volt optional)
  • Color:
    • Top, bottom and sides: Silver hammer tone
    • Front and back: Black
  • Size: 6.5" deep, 1.7" high, 6.5" wide
