Insignia- HDMI Audio Extractor NS-HZ340 (NO
POWER ADAPTER) T22
An Insignia HDMI audio extractor, such as the NS-HZ340 model, is a device that separates the audio signal from an HDMI video source and allows you to output that audio to a separate audio device like headphones or a soundbar. It passes the video signal through to a display without degradation while simultaneously providing analog (3.5mm jack) or digital (optical) audio outputs. This is useful for modern displays or projectors that lack specific audio outputs or for sending audio to a dedicated sound system while the video goes to a monitor.
