The adapter connects via a 1m USB cable to any available USB 2.0 connection on a laptop or desktop. It provides analog and digital audio output including SPDIF optical for home theater systems. Installation uses plug-and-play support in Windows 7, 8.1 and 10 with included software for output selection. It avoids the need for an internal PCIe sound card.

Sustained playback at 48 KHz with 120 dB SNR

The sound card supports 44.1 KHz and 48 KHz sampling rates for analog playback and recording. SPDIF digital output operates at 48 KHz while optical input passthrough handles two-channel audio at 48 KHz. Volume controls and mute buttons allow real-time adjustment during extended sessions. Buyers needing higher sample rates or more input channels should consider other solutions.

Questions about this item

Does the 48 KHz sample rate limit audio quality during long recording sessions?

The device supports 48 KHz for analog playback and recording, and SPDIF digital output is also fixed at 48 KHz.

How much heat or noise does the silver aluminium chassis produce when powered continuously?

The bus-powered adapter has no fan and draws power only from the USB 2.0 port, so it runs silently with negligible heat.

Which Windows version must already be installed for the plug-and-play driver to load?

Windows 7, 8.1 or 10 provides native driver support; no separate download is required.
