Motu, 8456, Audio Express 6x6 Half-Rack Hybrid FireWire/USB2 Audio Interface FireWire has long been recognized as a reliable, high-performance connectivity standard for professional audio interfaces. Meanwhile, high-speed USB 2.0 has also developed into a widely adopted standard for connecting audio devices to personal computers. To fully support both formats, the Audio Express hybrid audio interface is equipped with a FireWire jack (400 Mbit/sec) and a high-speed USB 2.0 jack (480 Mbit/sec). This gives you maximum flexibility and compatibility when connecting to today's ever-expanding universe of Mac and Windows computers. If your computer doesn't have FireWire, you can use USB. If it has both, then the choice is yours and may depend mostly on other peripherals you have. The Audio Express combo mic/guitar inputs are equipped with pristine, transparent preamps and offer individually adjustable 48V phantom power and -20 dB pad. The quarter-inch guitar jack provides high-impedance load characteristics suitable for passive and active pickups alike. For even more authentic feel and response when using virtual guitar amp and cabinet plug-ins, use a ZBox guitar impedance adapter. The Audio Express's analog trim circuits deliver clean sound, combined with the precision of digital control. Trim is adjusted at the input, before the mixer, so it applies to all mixes. Mix levels are controlled separately from trim, so you never sacrifice sound quality for a balanced mix. The Audio Express provides MIDI input and output featuring sample-accurate timing with supporting software. Connect a MIDI keyboard, sound module or control surface, and you are ready to go. The FireWire or USB connection to the computer carries both MIDI and audio so you don't need to connect an additional USB cable for MIDI.
