Product Description
Doug Fleenor Design's DMX512 isolators with amplifiers are considered some of the best products available for the distribution of lighting control signals. Isolators are used to eliminate ground loops and to provide protection from electrical storms, mis-connections, and equipment failures. With the exception of our Inline Isolator, all Doug Fleenor Design isolators with amplifiers may be used as line amplifiers to boost the signal from as little as 0.2 volts to full DMX output levels. Portable, rack, and wall mount units are available.
Available connector types: 5 pin XLR, 3 pin XLR, terminal block, RJ-45 (ESTA or Color Kinetics pinout), or mounted in a JBOX enclosure.
