HDMI audio extractor can come in handy when building a large home theater system with a Blu-ray player, projector, and a 5.1 surround sound speaker system (or a powered stereo speaker system). Since most projectors don’t have audio extractors or, in some cases, they have only AUX or RCA audio outputs, you need an audio extractor to separate the signal coming from the Blu-ray player, and then send video to the projector and send audio to your AV receiver (or to your powered stereo speakers). The extractor can pull stereo or 5.1 sound. The supported surround sound formats in 5.1 mode are PCM/LPCM, Dolby Digital 5.1, and DTS 5.1. Other, more advanced formats, are not supported. If you want DD+ support or DTS-HD support, you need to set the EDID switch to ‘’pass’’ and use the HDMI output.
These signals are HDMI-specific and hence require digital conversion for other formats. For audio, an HDMI audio extractor would be necessary for conversion to other formats. Why Would You Use an HDMI Audio Extractor?An HDMI audio extractor makes sense for any instance where you would need to convert HDMI to an audio-only source. Although there are times when an HDMI audio extractor may be your only solution (like when using an analog sound system), in some cases there may be alternative solutions that don’t involve an HDMI audio extractor. Example of Using an HDMI Audio Extractor Most systems will cover Dolby Digital 5.1 and DTS 5.1, while some will also support Dolby Digital Plus.
iArkPower A0301 is a little bit different than the previously mentioned extractors. It’s a little bit more capable, it can serve as an HDMI switch (multiple HDMI inputs), it supports ARC (only optical port) and, just like the previous extractors, it can output stereo and 5.1 surround sound. It’s slightly pricier than the previous HDMI audio extractors, but it’s worth it. What’s in the box? The crucial point is to ensure that any HDMI extractor device will allow these to pass through. If not, then you may be disappointed with the results. This LVY HDMI audio extractor doesn’t look like much, and come to think of it: this device doesn’t offer much in terms of features and high-quality materials.
The RCA L/R and SPDIF output can support both 2CH audio or 5.1CH audio including Dolby Digital 5.1CH and DTS 5.1CH(NOT support Dolby Digital Plus)
Tendak began integrating hardware connectivity solutions for audio & video connectivity, home theatre, structured cabling, and multimedia converters, among other things, in 2007 to meet the needs of customers. Tendak HDMI Audio Extractor is one of the best audio extractors with a 3.5 mm stereo output. However, keep in mind that this HDMI audio extractor does not work with Astro headsets. What’s in the box? The biggest advantage of the Kinivo 450BNT switch is 4K support (at 60Hz). The max supported color format is 48bit while the max bandwidth is 18Gbps. The switch also supports 3D videos and HDR.The inputs are all HDMI 1.4b (not 2.0). HDMI ports support 4K resolution (at 30Hz, not 60Hz) and 3D videos. The max supported bandwidth rate is 10.2Gbps and the color format is 48bit.
