ProFire Lightbridge - 34-in/36-out FireWire Lightpipe Interface
Top Features
| 32-channel Lightpipe I/O via FireWire > use digital mixers, preamps, AD/DA converters and ADATs with computer-based DAWs
|
 |
| up to 24-bit/96kHz SMUX operation > professional sound quality
|
|
| S/PDIF I/O > 2-channel transfers, submixes and monitoring
|
|
| ¼” headphone and balanced 2-channel outputs > flexible monitoring
|
|
| word clock and MIDI I/O > total synchronization and control |
The ProFire Lightbridge interfaces up to four Lightpipe devices with a PC or Mac via FireWire—perfect for integrating digital mixers, AD/DA converters and/or ADATs with most popular DAW software. The unit is capable of 32 channels of Lightpipe I/O, two channels of S/PDIF I/O and two-channel analog output for a total of 34 x 36 concurrent channels at 44.1 or 48kHz sample rates. (It also supports 16-channel Lightpipe operation at 88.2 and 96kHz sample rates via the S/MUX protocol.) The ProFire Lightbridge can output word clock as a master, or slave to external sync on any input, and MIDI I/O also accommodates MIDI Time Code and MIDI Machine Control. Independent volume controls are provided for the ¼” balanced outputs and front panel ¼” headphone jack. The ProFire Lightbridge is compatible with most DAW software including Pro Tools M-Powered 7 and higher*.
* Pro Tools M-Powered currently supports a maximum of 18 simultaneous inputs and outputs.

The Perfect Companion for Digital Mixers
The ProFire Lightbridge is designed with today’s digital mixers and workflow in mind. Record up to 32 Lightpipe tracks to your computer-based DAW simultaneously from a digital mixer. Or use your digital mixer to submix up to 32 DAW tracks while sending the submix back to the DAW via S/PDIF. Using a mixer’s built-in processing and automation leaves more CPU power for specific tracks that require CPU-intensive plug-ins.
Live Multitrack Recording
Combine the ProFire Lightbridge with up to four award-winning M-Audio Octane 8-channel preamps and you have a compact system ready to record up to 32 channels of input for live shows.
Pro Tools M-Powered Compatible
The ProFire Lightbridge is designed to work with Pro Tools M-Powered 7.3 and higher*. It’s never been easier or more affordable to integrate Lightpipe devices—digital mixers and ADATs—with the industry-standard digital audio workstation.

Transfers
Need to transfer tracks between an ADAT system and your computer? The ProFire Lightbridge does it with ease. Send up to 32 channels of Lightpipe simultaneously at 44.1 or 48kHz—or transfer up to 16 channels at 88.2 or 96kHz using the S/MUX protocol.
Build a Custom I/O Setup with the AD/DA Converters of Your Choice
ProFire Lightbridge plays nice with others too. Pick any ADAT Lightpipe-compatible A/D or D/A converter and utilize our fast and reliable FireWire driver technology to get the most out of your DAW.
