USB Stereo Audio Adapter External Sound Card with SPDIF Digital Audio and Built-in Microphone
StarTech ID: ICUSBAUDIOMH
The ICUSBAUDIOMH External USB Card lets you add an S/PDIF digital audio output or a standard 3.5mm analog
audio connection to your system through USB. By converting a single USB port into an external sound card with
microphone connectivity, you can conveniently bypass or replace an internal sound card without having to open your
computer case.
The USB DAC (digital-to-analog converter) provides a built-in microphone, allowing you to add audio recording
capability to your system without the need for additional hardware. This integrated microphone can also be placed
further away from your computer's speakers, reducing or eliminating feedback that is often problematic with laptops
that utilize an on-board microphone.
For home-theater quality sound, the external sound card 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). By implementing 3.5mm stereo microphone
connection the USB audio adapter equips you with the ability to attach an external stereo microphone as needed.
For added versatility this USB-powered sound adapter features a 15in attached USB cable, volume control, mute,
and microphone mute buttons for quick adjustments, a 3.5mm stereo microphone input, and a convenient LED
status bar to display the current sampling rate.
Backed by a StarTech.com 2-year warranty and free lifetime technical support.
