VS Preamps

Two XLR/TRS combo inputs are provided for the preamps, plus independent phantom power for each channel.
Low-Noise Power Supply

Designed to deliver a clean, balanced input and output, it provides a reliable foundation for any professional audio application or environment. When powered by the computer’s USB bus, the DUO-CAPTURE EX internally regenerates the incoming power, ensuring the ideal voltage for optimal sound quality and efficiency in mobile environments.
For Home Recording

The DUO-CAPTURE EX is compatible with all major computer platforms, including WDM/ASIO (Windows), Core Audio (Mac), and even iOS for the iPad.
For Mobile Musicians

For the ultimate in mobile convenience, the DUO-CAPTURE EX can be powered via your computer’s USB bus, three AA batteries, or an AC adapter (sold separately). Its premium preamps and low-noise design enable pro-quality results anywhere you record, indoors or out.
For iPad

Record vocals, guitar, keyboard, or other instruments with superb quality through the DUO-CAPTURE EX into the iPad using your favorite iOS apps.
