Clear-Com YC-36

The YC-36 is a two-channel beltpack adapter that lets a two-channel beltpack ride on a pair of single-channel intercom lines. It combines two single-channel three-pin cables into one two-channel six-pin connector, so an RS-602 or RS-702 beltpack can pull both channels from infrastructure that was wired one channel at a time. It saves rewiring a facility to six-pin when you add two-channel packs.

The adapter is passive and inline: two 3-pin XLR inputs on one end, a single 6-pin XLR output on the other. Drop it at the beltpack position and both partyline channels land on the pack through one connector.
