Alesis iO|26

AUDIO/MIDI 24-BIT/192KHZ FIREWIRE INTERFACE

Utilizing state of the art FireWire technology, Alesis' iO|26 offers professional–level features such as Alesis High Definition Microphone Preamps, Cirrus audiophile converters and jitter elimination technology, with high–quality 24-bit/192kHz audio input for PC or Mac. The iO|26 houses 2 headphone outputs, line-level inserts on the mic preamps, 48V phantom power, 5-segment signal/clip meters, and full MIDI and S/PDIF I/O in a convenient, portable tabletop design.

With ADAT lightpipe inputs for additional connectivity, the iO|26 gives you forward-thinking expansion potential, no matter what your recording sessions may demand. Flexible, routable Hardware Direct Monitoring allows you to send a customized, latency-free mix to each output pair. An AC adapter is also included, for computer users that don’t supply FireWire power.

Whether you find yourself on the road or in your own studio, the iO|26 gives you the Alesis performance that professionals have depended on for decades.
