Read The ProFire Lightbridge User's Manual (1.75 MB PDF)

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, 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 SMUX 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.

Main Features

	indicators for sample rate, Lightpipe I/O, MIDI I/O, sync source and power
	Kensington lock slot
	half-space rack chassis, optional mounting tray
	compatible with most major DAWs

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.

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.
