Digital Output Monitoring
When hardware monitoring is enabled, the analogue outputs are unavailable for monitor mixing. This is because the input signals
are not converted to digital and simply pass directly from the preamp to the analogue output. However, any digital output can still
be used as a monitor mix. This allows you to hear a monitor mix created with SaffireControl PRO, whilst still routing all 8 analogue
inputs directly to the analogue outputs with zero latency; a perfect solution for live recording situations.
The S/PDIF Output is probably the most suitable for this application as this output has a 'I/P Mix - S/W' crossfader (allowing the
blending of Inputs, created using the faders in the top left of the window, with a stereo backing track from the sequencer).
Digital Inputs and Sync Source Selection
As of Saffire PRO 2.0, S/PDIF and ADAT digital inputs are always 'ON' (unless you have disabled the ADATs for better CPU
performance). This means that you no longer have to turn the digital inputs 'ON' or 'OFF'.
The functionality of the sync source status LEDs has also changed. 'Desired' sync source and 'active' sync source are now
indicated as follows:
GREEN LED: 'Active' sync source
RED LED: 'Desired' sync source
For example, when you select a digital input as the Saffire PRO sync source, this digital input becomes the 'desired' sync source
until a different sync source is selected. If the digital input for the 'desired' sync source is physically connected and valid, the
'desired' sync source becomes 'active' (indicated by a GREEN LED).
If a sync source is selected while the digital cable is disconnected or invalid, the sync source will be set as the 'desired' source
(indicated by a RED LED). If the 'desired' digital input is then physically connected, the 'desired' sync source will then become
'active' and the LED will turn GREEN. Similarly, if the digital cable of the 'active' sync source is disconnected (or if the source
becomes invalid), the 'active' source will be reset to 'desired' (turning from GREEN to RED), and the 'active' sync source will be
reset to internal.
Please note that the 'desired' sync source functionality works differently for word clock sync. If word clock is selected as the sync
source and no digital word clock cable is connected, Saffire PRO detects this and automatically switches back to internal sync (as
with other sources). However, the 'desired' state is not remembered and when a valid word clock is connected again, word clock
must be manually selected as the source once again to sync to it.
Changes to Version 1
Using Multiple Units on a PC
In the Saffire PRO version 1 User Guide, it is stated that the Saffire PRO installer must be run individually for every unit being used
in a multiple device setup. For example, the first unit must be connected and the installer run, then the unit disconnected and the
next one connected then the installer run again, and so on for each unit. This is not the case for Saffire PRO version 2.
The Windows installer for Saffire PRO version 2 uses a coinstaller that automatically detects when an additional unit is connected
and updates accordingly. So, the installer only needs to be run once, not multiple times.
