USB Stereo Audio Adapter External Sound Card with SPDIF Digital Audio

StarTech ID: ICUSBAUDIO2D

The ICUSBAUDIO2D External USB Sound Card lets you add an S/PDIF digital audio output and standard 3.5mm
analog audio/microphone connections to your system through USB - a convenient way to bypass or replace an
internal sound card without having to open the computer case.

For home-theater quality sound, the USB DAC (digital-to-analog converter) offers 96KHz / 24-bit sampling rates for
both playback and recording, and a 3.5mm S/PDIF port with support for Dolby® Digital 5.1 surround sound (AC3)
and DTS® pass-through (Note: 5.1 surround sound is supported in Windows® only).

This versatile USB audio adapter features an integrated 3.5mm 4-position TRRS connection for your headphones
or combination headset/microphone. Also a convenient external volume control for quick adjustments, a hardware
EQ switch for Bass or Treble boosting, and an LED status bar to display the current sampling rate.

Backed by a StarTech.com 2-year warranty and free lifetime technical support.
