The LINDY HDMI 4K Audio Extractor allows you to extract audio from an HDMI while sending the video signal to your HD display or projector. The extracted audio can be sent to an AV receiver, speakers or sound bar in analogue and digital audio formats, allowing you to enjoy superior sound delivery.\n\nThe Audio Extractor is small enough to be easily located within an existing AV installation, and can be powered directly from a USB port on either an AV source or display device, reducing the need for additional sockets and power supplied to be used. If a USB port is not available then the Audio Extractor can be powered using the supplied USB DC cable in conjunction with a standard USB power supply or charger.
