7.1-Channel USB Sound Card 0478

The Ruth's sister 0478 is an external USB sound card that adds 7.1-channel analogue audio to any computer with a free USB port. It is built from aluminium alloy and weighs 50 g, measuring 4.3 × 2.9 × 1.1 cm. The device is powered entirely from the USB bus and requires no external supply. It suits users who need a compact replacement for a failed or missing onboard audio interface.

For laptops and desktops with a broken audio jack

This adapter works for anyone who wants plug-and-play stereo input and output on Windows, macOS or Linux without installing drivers. It is not for users who require hardware-accelerated surround processing, optical S/PDIF connectivity or professional-grade sample-rate conversion. Buyers needing more than two physical analogue connectors should look at a different class of interface.

Single USB Type-A interface

The only connection is a standard USB Type-A plug that carries both power and digital audio data. No additional cables, driver discs or configuration utilities are included in the package. Compatibility depends entirely on the host operating system's built-in USB audio class support.
