Alesis in Cumberland, R.I., announces that it is now shipping the iO4 USB audio interface ($149 estimated street price) for Mac, PC, and iOS devices to musical instrument and pro audio retailers. Connection to iOS devices requires the Apple iPad USB adapter, sold separately as part of the Apple iPad Camera Connection Kit.
The iO4 is a compact audio-recording interface for home and mobile recording setups. This 4-channel USB device for Mac, PC and iOS systems 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. The iO4 is compact enough to comfortably fit into laptop bag or backpack, yet contains high-quality components and circuitry suitable for the studio.
The iO4 has four input channels, each having an XLR microphone input, a ¼-inch TRS insert for external effects units and a ¼-inch TS jack that works with line-level sources and can accommodate direct connection of guitars. The iO4 features discrete-design preamplifiers and 48-volt phantom power on each of its four input channels, as well, for use with virtually all microphones and audio sources. The iO4 also has 5-pin MIDI in and out jacks.
The iO4 can connect to a second pair of reference monitors or route audio to external effects processors using its four available output channels. For remote tracking and alternative playback, the iO4 has a ¼-inch TRS headphone output. The iO4 features traditional 5-pin MIDI in and out jacks 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 for composing, recording, editing and mixing. Alesis states that the iO4 is compatible with "virtually all music software and apps."
