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

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.

Mode Display

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