Congure Ensemble as Clock Slave
1� Set the external device as the clock master�
2� Connect a digital audio cable (optical or coaxial) out of the external device and into Ensemble� Or connect a
BNC Word Clock cable out of the external gear to Ensemble’s BNC IN port�
3� Open Apogee Control and click the System button to reveal the System Sidebar�
4� Click the button under Clock Source and select the appropriate external connection from the drop-down
menu�
Set the Clock Source to “ADAT”, “SMUX”, or “SPDIF OPTICAL”
when using an optical cable� Ensemble’s front panel will also
reect the source.
Set the Clock Source to “SPDIF Coax” when using a coaxial
audio cable. Ensemble’s front panel will also reect the source.
Set the Clock Source to “Word Clock” when using a BNC word
clock cable. Ensemble’s front panel will also reect the source.
• BNC is the preferred method of transferring digital clock. Use this connection whenever
possible.
If Ensemble doesn’t receive or is unable to lock to an external clock source, the display’s clock
source indication will turn red, and the sample rate will blink�
When this happens, check your connections for a bad or miscongured cable, and make sure
the sample rate of the master and slave devices are set to the same value�
