Synchronising Saffire PRO
The SYNC window within Saffire PRO is the means by which to synchronise the hardware to an external source input on the rear panel:
The options are as follows:
S/PDIF – synchronises the hardware to the S/PDIF In
ADAT 1 – synchronises the hardware to ADAT In 1-8
ADAT 2 – synchronises the hardware to ADAT In 9-16
W/CLK – synchronises the hardware to BNC Word Clock Input
INT – synchronises the hardware to Saffire PRO’s Internal clock
Simply click the small LED alongside the desired source to attempt to lock to it. If you wish to lock to any of the digital audio inputs,
they must first be activated by clicking the ENABLE buttons to the right. Once enabled, they will appear as clickable options in the
SYNC list. After selecting a source with which to synchronise, (the small LED will illuminate to indicate selection), the words SYNC
LOCK will illuminate to inform you that Saffire PRO is successfully locked to the incoming signal.
It is often a good idea to synchronise to a digital signal when it is being input to ensure the most successful conversion. The clock
is embedded within its digital audio data stream and will ensure that no unwanted artefacts (normally clicks or dropouts) occur.
When two or more devices are both transmitting digital audio streams to the inputs of the Saffire PRO, they must be synchronised
with each other by 'locking' to an external device's clock. This can come from a separate word clock generator or the word clock
output of one of the digital devices (eg, DAT machine or digital mixing console). The master Word Clock must be connected to the
Word Clock input of all slaved devices using BNC cable. With the Saffire PRO, in addition to connecting a cable to the EXT WCLK
INPUT, the W/CLK SYNC button on SaffireControl PRO must be selected in order to establish Word Clock sync. All devices which
share a master clock should be set to identical sample rates and bit depths.

Click on the LED next to a source
to select it as the clock source - the
LED will light to indicate selection
and SYNC LOCK will light when a
lock has been achieved. Note that
the top three sources will only be
available when the corresponding
ENABLE switch is active
