[Big Ben](https://knowledge.apogeedigital.com/legacy-products?hsLang=en#big-ben) # What is the purpose of the WC OUT/TERMINATION LEDs on the front panel of Big Ben? ## When connecting word clock cables, it is essential that the receiving device be terminated at the word clock input. If word clock connections are chained (not recommended but possible with un-terminated inputs), a termination plug should be connected to the word clock input of the last device in the chain. The WCOUT/TERMINATION LEDs indicate whether each word clock output is under-terminated, over-terminated or properly terminated. For more information on the subject of word clock termination, please see the document[Big Ben Termination: How and Why](http://www.apogeedigital.com/pdf/bigben_termination.pdf) - [BOOM](https://knowledge.apogeedigital.com/boom?hsLang=en#main-content) -
