Apollo Software Manual Chapter 10: Multi-Unit Cascading 172
Multi-Unit Wiring
This page explains how to interconnect multiple Apollo units and the Mac computer.
Device wiring example with Apollo 8, Apollo 16, and Apollo Twin
Cables Required
One Thunderbolt cable for each Apollo unit
Important: All original (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 Mac and one cable between Apollo units.
Thunderbolt 1 or Thunderbolt 2 ports may be mixed and used for any/all connec-
tions.
The Mac 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 Mac, 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.
