Doug Fleenor DMX512 Dual Isolation Amp w/ Junction Box 4Uni. 4 In/4Out
Details
For the receiving end of long control runs, Doug Fleenor recommends the DMX512 Isolation Amplifier. It contains separate input and output power supplies. This allows the input circuitry to receive signals as low as 0.2V. 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.
The model 121Q has four isolators ideally suited for use with control consoles, which have multiple DMX outputs. Includes junction box mounting option.
