Apollo Expanded: Multi-Unit Wiring
The diagram below illustrates how to interconnect multiple Apollo units and the host
computer via Thunderbolt.
Important: For complete details about system operation when multi-unit
cascading, see the Apollo Software Manual.
Cables Required
• One Thunderbolt cable for each Apollo unit
Note: All Apollo rack units require Thunderbolt connections.
Apollo Expanded Wiring Notes
• A single Thunderbolt cable is required for all device interconnections. Connect one
cable to the host computer and one cable between Apollo units.
• Thunderbolt 1 or 2 ports may be mixed and used for any/all connections.
• The computer and all Apollo units must be connected to the same Thunderbolt bus.
• The Apollo device ordering and the Thunderbolt ports used (second port on Apollo
vs. second port on computer, placement in daisy chain, etc) is not important.
• In the wiring example diagram, the lower Apollo 8 is designated as the monitor
(master) unit. Connect speakers (including ALT speakers) to the monitor unit only.
• Do not connect more than one Thunderbolt cable between thev same two devices
(the Thunderbolt protocol is bidirectional).
• Do not interconnect any Word Clock, FireWire, ADAT, or MADI ports between any
Apollo units.
