If a Pro Tools|HD I/O audio interface is to be the clock source:
1. Connect a BNC cable between the LOOP SYNC OUT of one of the Pro Tools interfaces to the
LOOP SYNC IN of one RedNet 5. No daisy-chaining is required, as any other RedNet 5s will
be synchronised via their Ethernet connections.
2. In RedNet Control, set the RedNet 5 in Step 1 as the network master.
3. Also in RedNet Control, set the clock source for this same unit to “Loop Sync”.
Situation 3 – Single Pro Tools system with RedNet 5s (other Pro Tools interfaces optional), where
another RedNet unit is the clock master

In this system, another RedNet interface on the RedNet network is the clock master (i.e., not a
RedNet 5). For example, this situation might arise if there is also a RedNet 3 resolving its clock from
an audio input or word clock input.
1. In RedNet Control, set the relevant RedNet unit as the clock master in the Tools menu.
2. A RedNet 5 unit must be selected as the Pro Tools clock source. In the Pro Tools Hardware
Setup window, set Clock Source to Internal for one RedNet 5.
3. If there are also non RedNet 5 Pro Tools interfaces in the system, connect LOOP SYNC OUT
on one RedNet 5 to LOOP SYNC IN of a Pro Tools interface, and daisy-chain any subsequent
units in the usual manner.
Situation 4 – Multiple Pro Tools systems, each with RedNet 5s
The guiding rule here is:
• one of the Pro Tools systems may be configured as described for any of Situations 1, 2 or 3
above;
• all other Pro Tools systems must be set up as described in Situation 2, with one of the
RedNet 5s on each being assigned as the clock master.
It is important to note that when more than one Pro Tools system is connected to the RedNet network,
all audio routing must be conducted using Dante Controller instead of RedNet Control. For audio to
be transferred between Pro Tools systems, all the systems must be set to run at the same sample
rate.
