recording setups. This four-channel USB device for Mac and PC-based systems

four out) in 16-bit mode or four channels (two in, two out) in 24-bit mode. The iO4

yet contains high-quality components and circuitry suitable for the studio.
PROFESSIONAL I/O
The iO4 has four input channels, each having an XLR microphone input, a 1/4-inch
TRS insert for external effects units and a 1/4-inch TS jack that works with linelevel sources and can accommodate direct connection of guitars. The iO4 features
discrete-design preampliers and 48-volt phantom power on each of its four input
channels as well for use with virtually all microphones and audio sources.
Producers and musicians will appreciate the ability to connect a second
pair of reference monitors or route audio to external effects processors
using iO4’s four available output channels. For remote tracking and
alternative playback, the iO4 has a 1/4-inch TRS headphone output.
