Alesis has announced that the iO4 USB audio interface for Mac, PC, and iOS devices, is now shipping.
The iO4 enables users to record and monitor up to eight channels of audio (four in, four out) at 16-bit resolution, or four channels (two in, two out) at 24-bit. It is compact enough to comfortably fit into laptop bag or backpack.
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, allowing the connection of nearly any microphone or audio source to a computer. High-quality analog-to-digital and digital-to-analog converters ensure that every detail of each session is captured and played back faithfully.
The iO4 also fosters the ability to connect a second pair of reference monitors or route audio to external effects processors using the iO4’s four available output channels.
For remote tracking and alternative playback, the iO4 has a 1/4-inch TRS headphone output. It also has traditional 5-pin MIDI in and out jacks, making it a suitable interface for connecting MIDI controllers with music software and iOS apps.
The iO4 is class compliant for plug-and-play operation with Mac OS X and Windows XP, Vista and 7. It is compatible with ASIO4ALL drivers, available for free download, for enhanced Windows performance.
Steinberg Cubase LE music software is also included, and the iO4 is compatible with virtually all music software and apps.
The iO4 is now available from pro audio and MI retailers with an estimated street price of $149.
