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 23.
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
These ports use the MADI (Multichannel Audio Digital Interface) optical protocol for interconnecting with other
audio hardware devices in the digital domain. MADI input and output ports are provided.
The MADI ports relay the Monitor, Cue, and Auxiliary busses between multiple Apollo 16’s when they are con-
nected in a multi-unit configuration for increased simultaneous I/O. For details about MADI features with Apollo
16, refer to the Apollo Software Manual (see “About Apollo 16 Documentation” on page 8).
