Compact 7.1 USB Audio Adapter

This Corn Electronics USB sound card adds a 7.1 channel audio environment to any desktop or laptop through a standard USB Type-A port. It draws power directly from the bus, so no external supply is needed, and the tiny 45 x 25 x 14 mm body weighs only 14 g.

Suits stereo headset owners wanting virtual surround

The adapter upgrades existing stereo speakers or earphones to a 7.1 channel experience and provides dedicated microphone and speaker mute keys plus volume controls. It is not for buyers who need native 7.1 analogue outputs or hardware-accelerated DSP features beyond the USB Audio Class 1.0 implementation.

Driverless USB Audio Class 1.0 compliance

The device follows the USB 2.0 Full-Speed 12 Mbps specification and the USB Audio Device Class 1.0 standard, enabling plug-and-play operation on Windows 98SE through 7 32-bit, Server 2003, Vista, Linux and MacOS without installing separate drivers.
