ERROR
The Error LED indicates a serious system or setup error,
for instance the lack of selected digital input or the lack
of selected input clock.
AES, SPDIF and ADAT/TOS
Indicates which digital input source that is currently
selected in the I/O menu.
48 kHz and 44.1
A steady LED indicates the current sample rate. If a
digital input is the audio source and Clock Select is set
to internal 44.1 or 48 kHz the LED’s show the incoming
clock rate - not the selected internal rate.
48 kHz lock is indicated with a green LED
44.1 kHz lock is indicated with a yellow LED, - as this is
not standard sample rate in broadcast.
If a digital input is selected and not available, 48 and
44.1 kHz LEDs start blinking. This also happens if the
selected input clock is lost.
COM/REM
The LED is lit when commands are received through the
remote COM port.
EDITED
Indicates that settings have been changed compared to
the currently recalled preset.
