Apollo Thunderbolt Software Manual Multi-Unit Cascading 196
Multi-Unit Wiring
This page explains how to interconnect multiple Apollo units and the computer.
Device wiring example with Apollo 8, Apollo 16, and Apollo Twin
Cables Required
• One Thunderbolt cable for each Apollo unit
• (Windows) Qualified Thunderbolt 3 to Thunderbolt adapter for computer connection
Important: All connected first-generation (silver) Apollo and Apollo 16 units require the
Thunderbolt Option Card.
Apollo Expanded Wiring Notes
• A single Thunderbolt cable is required for all Apollo unit interconnections. Connect one
cable to the host computer and one cable between Apollo units.
• (Mac) Thunderbolt 1 or Thunderbolt 2 ports may be mixed and used for any/all
connections.
• (Windows) Windows 10 and built-in Thunderbolt 3 (via USB-C port) are required.
Connections to Thunderbolt 1 and Thunderbolt 2 ports are not supported.
• 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 versus
second port on computer, placement in daisy chain, etc) is not important.
• In the wiring example diagram, the Apollo 8 in the center 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 the same two devices (the
Thunderbolt protocol is bi-directional).
• Do not interconnect any Word Clock, FireWire, ADAT, or MADI ports between any Apollo
units.
