Hello,
I reciently added a Apogee big ben to my setup and on the interface of the unit i notice that the indication lights our not lit up

does this mean that the word generator is not feeding the motu unit?
or that the motu has an issue with "termination" light not idicating proper termination even though it is ok??
Anyone

For the sake of anyone else clocking from Apogee Big Ben:
Mark of the Unicorn Hardware
When a MOTU interface is connected without termination, Big Ben's
Termination LEDs light correctly when the MOTU interface is powered
off, but indicate under termination when the interface is powered on.
When a MOTU input is terminated with a 75 ohm load, Big Ben's red
(over-terminated) LED lights. Thus, do not terminate MOTU inputs; this
does not affect clock performance.
