Setup guide

Powering up the Delta-Link and Pro Tools System
At this point you can start up the Delta-Link and Pro Tools computer and the Pro Tools software. However, do not load a
s
ession with a different sample rate from the one received by the Alpha-Links and Delta-Link. The Delta-Link expects to
receive a clock signal at the sample rate determined by the session. If a session is opened at a different sample rate from
the current one, the Delta-Link Clock LED will flash until a clock signal at the appropriate sample rate is received. The
clock source in Pro Tools must also be set to ‘Internal’ for the first 192 unit (more about this later).
The settings and/or descriptions in this setup guide are applicable for a session at 44.1 or 48kHz only.

Pro Tools Menu: Setup | Hardware
Click ‘Hardware’ in the Pro Tools Setup menu to make the settings described in the following diagrams. First, check that
the Delta-Link is recognized as four Digidesign 192 units and set the Clock Source as described below.

. The ‘Clock Source’ must be the first 192 unit (indicated by the dot in
front of its name), and must always be set to ‘Internal’ (indicated by the
tick), even though you may be using an external clock master device. In
reality the Delta-Link is always clocked externally, but the Pro Tools
software has no ‘knowledge’ of the Delta-Link.

. Make sure you see four
192 peripherals. If not, check
the Digilink connections.
