Cumberland, RI (January 25, 2012)—Alesis has started shipping its iO4 USB audio interface for Mac, PC and iOS devices.
The iO4 is a compact audio-recording interface for home and mobile recording setups—a 4-channel device spec'd to record and monitor up to eight channels of audio (4-in, 4-out) at 16-bit resolution, or four channels (2-in, 2-out) at 24-bit.
The iO4 has four input channels, each with an XLR microphone input, a 1/4-inch TRS insert for external effects units, and a 1/4-inch TS jack that works with line-level sources and can accommodate direct connection of guitars.
Discrete-design preamplifiers and 48-volt phantom power are provided on each channel, which is said to allow musicians to connect any microphone or audio source to their computer. Analog-to-digital and digital-to-analog converters are also included, along with Steinberg Cubase LE music software.
