With the CHAUVET DJ D-FI XLR pack, you can make any DMX-compatible light wireless. The wonders of wireless DMX control have arrived to previously non-wireless lights with D-Fi XLR. This cutting-edge technology provides instant wireless communication through compact battery-powered wireless D-Fi receiver or transmitter units that plug directly into the XLR port of DMX-compatible lights. Contact pins charge all D-Fi XLRs without the need for any cables. The D-Fi XLR Pack includes 1 transmitter, 3 receivers and 1 multi-charger. The multi-charger simultaneously charges up to 8 D-Fi XLRs (additional units sold separately). D-Fi XLR Pack even has 2 additional USB ports to charge additional devices.
