Mackie 400F Appendix C: Technical Info, FireWire Connection, Onyx 400F Specifications

FireWire Connection

The Onyx 400F is equipped with two 6-pin FireWire connectors and comes with a 6-pin to 6-pin FireWire cable. This works with Macintosh laptops and desktops, and most PC desktops with a built-in FireWire connector or with a PCI or PCMCIA FireWire card added.

Many laptop PCs have a 4-pin FireWire connector. If this is the case, you will need to purchase a 6-pin to 4- pin FireWire adapter cable. These are readily available at computer stores or online.
