If the active reference source is lost, the unit will select the next option in the
sequence.
If the Auto-Slave option in the “Function Menu” is turned On the unit will
automatically slave when a suitable reference is connected. If both AES
Reference and Word Clock are connected, AES Reference takes priority. Word
Clock may be selected by pressing the 
Master/Slave 
button – it moves down
the priority list.
Once slaved, the unit can internally multiply the reference input sample rate by 2
or 4, if required, by pressing the 
Multiplier
 button. The Master Clock must be
set to a suitable sample rate:

Output Format
Menu 
Up
The 
Output Format
 button is dual function – on its own (
blue
 type on the front
panel) it sets the output format (single, dual, quad AES, etc). With the other
menu buttons ( 
white
 type on the front panel) it is the 
Up
 button.
Pressing the 
Output Format
 button repeatedly causes the output format to
cycle through the allowed options from the sequence:
Single AES
 ... 
Dual AES
 ... 
Quad AES
 ... 
Single AES
 ... etc.
If any format is not available at that sample rate, it is skipped from the
sequence.

The single digit LED mode display to the right of the Format button shows the
output format:
