The I/O and audio quality necessary for critical project studio work at an unbelievable price!

Utilizing DICE II FireWire technology for big bandwidth, fast signal handling, and lots of digital headroom, the Alesis io|26 is a professional”level computer recording interface in an easy-to-use tabletop design. You get 8 analog channels and 18 digital channels; Alesis high definition microphone preamps; Cirrus audiophile converters and jitter elimination technology; and high”quality 24-bit/192kHz audio conversion circuitry.

The io|26 audio interface has line-level inserts on analog channels, 48V phantom power, 5-segment signal/clip meters, 2 headphone outputs, 8 line-level outputs, turntable inputs, S/PDIF I/O, dual MIDI/O, and includes Cubase LE recording software. Dual ADAT lightpipe inputs give you forward-thinking, professional expansion potential for your recording setup. Flexible, routable Hardware Direct Monitoring allows you to send a customized, latency-free mix to each output pair. The io|26 interface runs on FireWire bus power or AC power with the included adapter.
