12VDC Power Adaptor Input. This is where you plug the provided power supply into
the FIREBOX. Please check the power supply to ensure that it is the correct voltage
and plug type for your country. Note that you can also power your FIREBOX with a six-
pin FireWire port from your computer instead of using the external power supply.
FireWire Ports. There are two firewire ports on the back of the FIREBOX. Both
FireWire ports are standard 6 pin firewire jacks. If your computer has a six-pin FireWire
port you can power your FIREBOX from the FireWire connector. If your computer has
a 4 pin connector, then you will need to get a 4 to 6 pin connector to connect your
FIREBOX to your computer, and use the external power supply. Either port can be
used to connect the FIREBOX to a FireWire port on your computer.
MIDI and S/PDIF IN and OUT.
MIDI and SPDIF I/O can be connected to this DB-9 connector breakout cable
(included). The S/PDIF I/O allows the FIREBOX to receive and transmit audio from/to
other digital audio devices. The S/PDIF standard allows for two channels of audio to
be transmitted at up to rates of 24bit/96Khz. Word clock is the synchronizing signal
that indicates the sampling frequency or rate of sample words over a digital audio
interface. Note: When using SPDIF In, you must select SPDIF in your FIREBOX
Hardware Control Panel.
