This HDMI® audio extractor lets you separate stereo audio from your HDMI video signal and connect it to a 3.5mm audio device, such as your stereo sound system or desktop speakers. You can also extract the audio from the HDMI signal and integrate it into an optical TOSLINK® application, using the included digital SPDIF adapter. Your latest consumer A/V equipment probably only offers an HDMI output. This can make it difficult to integrate devices, such as your new Blu-ray™ player or computer system, with your existing audio equipment or desktop speakers. The HDMI audio extractor is USB powered using the included power cable, for easy integration with your computer systems. The adapter also features a small footprint that discreetly blends into your hardware setup, for a uniform look.
