1 OPERATION INTRODUCTION Congratulations on choosing this Clear-Com product. Clear-Com was established in 1968 and remains the market leader in providing intercoms for entertainment, broadcast and industrial applications. The ruggedness and high build-quality of Clear-Com products defines the industry standard. In fact, many of our original beltpacks and main stations are still in daily use around the world.
TWC-701 AND TWC-704 SYSTEM The TWC-701 is a stand-alone adaptor that combines two standard Clear-Com intercom channels (on two separate cables) onto a single standard 3-pin microphone cable. It does this by combining one channel of intercom audio with the 30 volts DC operating power. The TWC-704 adaptor is four channels of the TWC-701 in a single 19-inch rack mount chassis. Clear-Com intercom products with TW functionality accept two individual channels of intercom from one single 3-pin cable.
TWC-701 CONNECTORS AND CONTROLS The TWC-701 has no operating controls. Figure 1-2: TWC-701 Rear Connectors The TWC-701 panel contains: 1. 3-pin male XLR type output connector, labeled “TW.” 2. 3-pin female XLR type input connectors, labeled “CH B” . 3. 3-pin female XLR type input connectors, labeled “CH A”. 4. One circuit breaker reset button. 5. One red LED “short” indicator. TWC-701 CONNECTION AND OPERATION 1.
Note: 1-4 Only Clear-Com intercom stations equipped with a TW option should be connected to the output of the TWC-701. If a station not equipped with the “TW” option is connected to the TW intercom line, the studio portion of channel A will be loaded down, reducing volume level and changing sidetone characteristics on that channel. (However, if a non-TW equipped station is accidentally connected to the TW line, no damage will be caused to the TWC-701/TWC-704 or any system component.
TWC-704 CONNECTORS AND CONTROLS The TWC-704 has no operating controls. The TWC-704 panel contains: Figure 1-3: TWC-704 Rear Connectors 1. Four 3-pin female XLR type input connectors labeled “CH B”. 2. Four 3-pin female XLR type input connectors labeled “CH A”. 3. Four 3-pin male XLR type output connectors, labeled “TW.” 4. Four green LED “power good” indicators, labeled “PWR.” TWC-704 CONNECTION AND OPERATION 1.
