AES/EBU Indicates that AES/EBU is being used
as the clock source for the MADI ports when us-
ing Sample Rate Conversion (SRC). If AES/EBU is
selected as the Clock Source for Sample Rate
Conversion in the Hardware Setup dialog, but
no valid word clock is detected, the AES/EBU
LED blinks on and off until a valid clock source
is selected.
Word Clock Indicates that the dedicated (SRC)
Word Clock ports are being used as the clock
source for the MADI ports when using Sample

vert in the Hardware Setup dialog, but no valid
word clock is detected, the AES/EBU LED blinks
on and off until a valid clock source is selected.
