Product Description
Doug Fleenor Design MARCONI-SP Wireless DMX Receiver - 3 Isolated Outputs
The Marconi wireless system from Doug Fleenor Design allows DMX512 distribution where cabling is not practical. Doug Fleenor believes cable is more reliable than wireless, but recognizes the advantages of wireless systems such as quicker setup, building top to building top (or cross river) communications, fewer wires to tape down, as a backup to a cable link, for troubleshooting, for focusing before the FOH cables are installed, and so on.
Marconi components are 100% compatible with W -DMX products from Wireless Solution as well as from other W -DMX partners.
The Marconi splitter (Marconi SP) receives all 512 channels (one universe) of DMX wirelessly through the W-DMX technology and provides three isolated DMX512 outputs. Outputs are isolated from each other using 2500 volt optical couplers and 600 volt DC/DC converters.
Indicators include POWER, ASSIGNED (lights when the unit is assigned to a transmitter), RF LINK (lights when the assigned transmitter is on and within range), and DMX512 (lights when DMX512 is available at the outputs). A 2 dB rubber whip antenna is standard. Gain antennas are available to increase reception range. The attached power supply operates from 100 to 240 volts AC.
