Review: Needed to connect a new tv to an old stereo receiver. It was very easy to setup. No issues getting 5.1 vs 2 channel as some noted. I thought this would be the best connection method, take advantage of the 6 channel input on my stereo. There is one aspect I didn’t think of. there is no method to tune or balance the frequencies of each channel. The cut off to the center and fronts is quite high and thus without a subwoofer connected there is very little bass. Perhaps the alternate method to buy a digital to analog converter and use the stereo’s surround options and settings to get the best sound is a better option for my scenario. But I can’t reduce the rating based that.
Review: The SOUTHSKY 5.1/2.1 Audio Rush Digital Sound Decoder works great for connecting my stereo Sennheiser headphones. I'm taking 5.1 surround sound from a gofanco extractor and decoding to analog RCA outs. This unit has a switch that combines the 5 surround channels making left front and right front mixed stereo outputs plus subwoofer out. I am finally able to keep surround sound playback in the room and provide headphone audio for my wife. Other splitters I have tried always switched my Receiver from 5.1 surround encoding to PCM stereo when I connected to use the left and right RCA outputs. This unit connected to a gofanco HDMI to HDMI extractor set to 5.1 surround makes my Receiver stay in surround mode so all my devices ( Firetv, Blu-ray player & Dish TV) play out surround sound.

*by B***N on 8 May 2023*

Was trying to use a set of computer speakers for my home theatre setup. The sound floor is awful, the speakers buzz quite a bit at anything more than half volume and they’ll be there a lot because it made the speakers really quiet. While the surround sound effect was really good with great locational audio (sound stage)
