| Post subject: | Cheap AC3 to RCA Decoders on eBay |
Seeing some devices on eBay listed as AC3 to RCA decoders. Are these AC3 demodulators? It looks to have the right inputs, but clearly are a new device. Just wanting to know if these are cheaper options than vintage demodulators. |

Please provide the link for the product. They are most likely not RF input. |

Ah good point on the RF. https://www.ebay.com/itm/AC3-DTS-Digital-Optical-Audio-To-5-1-Channel-Stereo-Analog-6-RCA-Converter-120dB/264172057434 https://www.ebay.com/itm/MOCHA-DTS-AC3-5-1CH-Audio-Digital-Sound-Decoder-Optical-SPDIF-Coaxial-to-6RCA-US/254844586085 |

Wow, these would be cool if they do work. The second one looks it but for 110 why not just get a tried and true decoder or AV with AC3 built in. |

In China “AC-3” means DD 5.1. Also “SD” and “CRT” are often used interchangeably even though there are VGA CRTs and sub-VGA LCDs... I’d be extremely surprised if these worked with RF. This is honestly more of a pro device, despite its puny price. Unless you’re throwing a full sized theater together on the cheap or building a tube state home cinema I don’t know why anyone these days would want to convert a digital signal to six line level ones. There is no affordable home gear that accepts analog surround from direct inputs anymore. This is like the HK ADP-303 with the RF demod (the important part) missing. |

What purpose would these serve? it seems unnecessary if you have an AVR. |

If you want 5.1 in a church, for example, you could run each line out to a powered PA. Theater equipment is probably still made this way since amps can be separate then. In the home they’ve been out of date since the early 2000s. |
