Apollo 16 Hardware Manual Rear Panel 16
Host I/O
Important: Connect only one Apollo 16 FireWire or Thunderbolt port to the host computer.
(9) Expansion Bay
The expansion bay is where the Universal Audio Thunderbolt Option Card is installed, providing access to all of
Apollo 16’s features and functionality via Thunderbolt-enabled computers.
Refer to the Installation & Setup Guide included in the Thunderbolt Option Card package and our website for
complete details about installation, configuration, and use of Thunderbolt with Apollo 16.
(10) FireWire 800 Ports
Apollo 16 uses FireWire to communicate with the host computer system when the Thunderbolt Option Card is
not in use. When Apollo 16 is properly connected and configured, the HOST indicator (#2 on front panel) is il-
luminated.
Apollo 16 has two FireWire 800 ports. Only one port is used to connect to the host computer; the second port
can be used for daisy-chaining multiple FireWire devices such as external FireWire hard drives. For more
FireWire information and recommended interconnections, see ““FireWire Basics” on page 22.
Note: Apollo 16 cannot be bus powered and it does not supply bus power from its FireWire ports to
other devices.
(11) MADI Optical Ports
The MADI I/O ports use the MADI (Multichannel Audio Digital Interface) optical protocol for Apollo 16 intercon-
nections. The MADI ports relay the Monitor, Cue, and Auxiliary buses between two Apollo 16 units when multi-
unit cascading via FireWire for increased simultaneous I/O.
Note: The MADI ports support Apollo 16 interconnections when multi-unit cascading via FireWire only.
Connections to other MADI devices is not supported.
