11. Power Supply Connector – Connect the 12V DC 1A power supply here. Use only the power supply
provided with the interface or an equivalent power supply with the same rating and polarity.
If you are using the six-pin-to-six-pin FireWire cable to attach ProFire Lightbridge to your computer, the
interface will draw power from your host computer. It is recommend that you leave the power supply
disconnected while operating ProFire Lightbridge on a bus-powered 6-pin FireWire port.
NOTE: Your computer’s 6-pin FireWire port may not be able to supply adequate power to ProFire
Lightbridge if additional devices, such as external FireWire harddisks, are powered through the same
FireWire port. Also, 6-pin FireWire ports on PCMCIA FireWire expansion cards for laptops are generally
not bus powered. Use the power supply or connect the ProFire Lightbridge to a different FireWire port
to remedy potential low power problems you may encounter.
12. Kensington Lock Connector – Connect a standard laptop-style locking security cable here to protect
your ProFire Lightbridge from theft or accidental breakage.
13 FireWire Port – Connect ProFire Lightbridge to your computer using one of the supplied FireWire
cables.
14. MIDI, S/PDIF, Word Clock Multi-Pin Connector – Connect the included breakout cable to this
multi-pin connector. The breakout cable provides the following connections:
• S/PDIF coaxial (RCA) digital input and output
• MIDI input and output connectors
• Word clock BNC input and output connectors
15. Optical Inputs and Outputs – Each of these optical inputs and outputs can support eight channels of
digital audio at 44.1 or 48kHz, or four channels of digital audio at 88.2 or 96kHz.
NOTE: These inputs and outputs do not support the two-channel S/PDIF optical format.
16. Line Outputs – These 1/4” TRS connectors output a balanced, line-level analog signal.
By default, these outputs mirror the S/PDIF digital output, but can be configured in the control panel to
appear as an independent set of outputs for your DAW. The analog line outputs’ signal level is controlled
by the front-panel Output Level Control knob (3).
NOTE: The Headphone Output (1) always mirrors the signal that is coming out of the Line Outputs.
