Make your home theater perfect. With this converter, you can connect the audio signal from your existing HDMI signal. This allows you to send the HDMI video signal to up to two devices such as a TV, projector, or monitor, while outputting the HDMI audio signal to a sound system, amplifier, or headphones. There are three options: 1. Pass: The HDMI signal (audio + video) is simply passed through the device without separating audio and video. 2. 2CH: Here, the HDMI audio signal is converted to Toslink and RCA (stereo, R/L). 3. 5.1CH: Conversion to Toslink 5.1 (Dolby Digital 5.1). This provides solutions for digital entertainment centers, HDTVs, set-top boxes, DVDs, projectors, and much more.
