The LED corresponding to the active port glowsgreen; if all four LEDs are off, the HD I/O is disabled. Port A is thedefault, B is optional and the other two are not currently supported.• Dual AES Input & Output — These two LEDs indicate the input andoutput AES clock speed. The indicator glows green if you are using 1xAES, and is off if you are using double-speed.• Clock Source — The indicator which is lit denotes the source fromwhich digital clock is derived. If the indicated clock source is not themaster, then the DS (digital sync) indicator will light. The last two LEDsat the right glow green for channels 1-2/3-4 and amber for 5-6/7-8.• JA — When the jitter attenuation circuit is locked to the clock source,this indicator glows green. If it is red, the circuit is not locked and audiooutputs will mute.• Word Sync Lock — This indicator glows green if the HD I/O is lockedto an input word sync signal, and amber if it is not locked. If there is nosignal at the word sync input, the indicator is off.
