Toshiba : 4CHVOUT 4 Channel Analog Out Card to be used with Toshiba Surveillix DVR'S

Notebook pro audio recording has never sounded so good, or been this convenient and affordable. Indigo IO offers one stereo 1/8 inch analog input and output on a Type II Cardbus card powered by your notebook computer. It combines this with 24-bit/96kHz converters for the quality you deserve. Also included is a 6 foot audio cable for RCA or 1/4 inch connections. A unique feature of the Indigo IO is the use of virtual outputs. Indigo IO appears to software as if it has eight separate outputs, which are digitally mixed down to the physical outputs using Indigo IO's console software and its on-board DSP. This makes Indigo IO compatible with all popular multi-track software. And, with Echo's multi-client drivers, more than one application (such as an editor and a software synth) can be playing back through Indigo IO at the same time.Minimize
