Why We Love This Product!

Amazing Audio Interface Value!

The Alesis iO4 compact USB audio interface is your studio problem solver. Regardless of how much great gear you have, you've still got to get audio into, and back from your computer. The Alesis iO4 comes to the rescue with top-shelf converters and mic preamps, up to eight channels (4-in, 4-out) of ultra-clean audio, and a truckload of I/O. You can even plug your guitar straight in, and route signals out to external effects processors. If your old audio interface isn't making the grade, the Alesis iO4 will float your boat.
