"Y" Not Have it Both Ways?

Are you a longtime Mac user? If so, you've probably purchased a few peripherals along the way—devices like DV camcorders, external drives, and even an old iPod® or two—and some of them probably have FireWire 400 interfaces (a.k.a. IEEE 1394a and iLink®). Your older Mac probably had at least two FireWire ports, so connecting more than one of those devices at the same time was easy. But, if you've purchased a new iMac, Mac mini, or MacBook Pro in the last couple of years, you may have run into a couple of problems when you tried to connect those great devices—there's only one FireWire port, and the connectors didn't match! Sonnet's Yin•Yang FireWire 800 to FireWire 400/800 mini hub solves both problems.

Fusion Enclosure Back PanelYin•Yang plugs into the single FireWire 800 (IEEE 1394b) port found on most new Mac computers and enables you to connect and use a FireWire 400 device (the Yin) and a FireWire 800 device (the Yang) at the same time. Yin•Yang doesn't need one power adapter, yet it will support a bus-powered 2.5" drive on either port. Fully IEEE 1394 compliant, this mini hub requires no drivers, supports all industry standard FireWire peripherals, and allows you to plug in and disconnect devices without shutting off your computer.
