The theater where I just closed a show had a cable I’ve not seen before. A well respected community theater company near Philadelphia has a Leviton 7xxx system. The cables running to the dimmer packs looked like mike cables, but one end had a second XLR connector coming out, a Y connection. The cannon plug on the end with only one XLR had five pins. The documentation specifies five and three pin connections. Standard coax ran between the connectors. The spice had a lot of electrical tape. I couldn’t get close enough to inspect thoroughly. Things seem to work OK but they want to add a sixth dimmer pack. They’ll need to connect the new pack to the dimmer. Does Leviton make this coax Y cable? Some one else? Or was it home made?
