This 2CH 3-pin XLR cable adapter combines two intercom channels on a single 3-pin cable for beltpacks with the TW option. All TW beltpacks requires a Clear-Com TWC-701 or TWC-704 circuit for two-channel operation. The adapter allows the connection of TW beltpacks to two-channels of a multichannel Clear-Com system. The TWC-701 combines the channels (A and B) from two separate cables onto a single standard microphone cable. Each TWC-701 or TWC-704 module can drive up to 15 RS-603 series beltpacks.
