SPDIF to Analog converter.

This isn't a repair question how ever, I need a SPDIF to analog converter because My LCD TV only has SPDIF for audio output, my new Home theater only has LINE inputs (stereo) but does have digital output? (go figure). I would like one that passes the 5.1 signal, so that my surround system will process it. Those I have found, seem to indicate this 5.1 signal is filtered out? What? Huh? If you want 5.1 signal then you need a Dolby Digital decoder built into the receiver itself. They have SPDIF to analog converters but those faggots will only covert a uncompressed stereo stream into line level but will probably ingore the dolby digital stream if your lucky. Since your Home Theater is new, take the dicksucker back and exchange it for something that has a Dolby Digital input. Also you didn't specify if the digital output is Optical or Coaxial. SPDIF is the data flowing through the mother****er, not the connector itself. SPDIF does not support 5.1 surround sound, it only supports stereo sound. |

That COAX digital programmable output is probably to hook up the system to a real surround system to play the USB and SD Card through it. it just does not have a SPDIF input on it. and the TV does not have the analog line output.. It does have how ever, a head jack (stereo) output which I am wondering if that carries the 5.1 signal ? No, and neither will the SPDIF because SPDIF is stereo only. You're confusing SPDIF with Dolby Digital. They are not the same thing. admittedly, it's a cheap system.. 1000Watts Colby. But, since it was free, I'd like to get the TV piped into it. Then you have nothing to lose by taking the faggot out to the back yard and beating it to death with a sledgehammer. You can use the headphone jack but you're only going to get stereo sound, not surround. It sounds like you would only get stereo out the digital output because like I said, SPDIF is stereo, not surround sound. SPDIF is the protocol flowing through the cable, not the connectors on the cable. |

The solution is that he needs to buy an entirely new surround sound system. |

Since Jamie has broken the cardinal rule of not supplying model numbers we haven't a clue what on earth he has.

Should that TV have a standard analog stereo output which will include the original Dolby Surround information from the transmitted film soundtracks. Maybe there might be smarts inside the surround system to process that as Pro Logic. Dunno. No model number. If the system Pro Logic capable, and line level analog stereo audio is not available on the TV, I think Jamie should be capable, as someone who has an FCC radio ticket, of wielding a soldering iron and sorting that out. Or padding down the headphone output. Or buying a better (and 5.1/7.1) home theatre system based around a separate amplifier/receiver, and using the digital connection. -- Adrian C |

The solution is that he needs to buy an entirely new surround sound system. I already have an existing system that uses LINE input from my 61"LCD into the surround. It properly decodes the 5.1 just fine.. !. I don't know where you're getting this idea from. The line inputs of my new home Theater does decode properly when I use a smaller LCD TV I have that just happens to have analog line out on it. So I know the system works as it should. I just need to convert this signal from the coax digital with out great pain. |

I'm not trying to defend a piece of junk, but a system *can* be designed to handle that peak power without drawing that same amount of power from the mains. Back in the days of just regular stereo, I was always amazed that I could play my system at an almost painful level and with the average power to the speakers remaining below 5 watts. Of course, the peaks were many many times higher. A good system would put out 5 watts with 200 watt peaks. A cheap system would put out 5 watts with 10 watt peaks. The difference in sound quality was very obvious. Anyway, my only point is the peak power output of any system can be a lot more than multiplying the mains volatage by the mains current. Large power supply capacitors provide the energy for the short peaks. |

Large power supply capacitors provide the energy for the short peaks. The actual output wattage vs the computed instentanious peak wattage is the key to wattage measurements. Every manufacturer uses their own formulas but most actually include the wasted current used by the output stages as actual effective wattage. I had a Fisher unit that was rated at only 8 watts from 8 to 20,000 cycles and it was far superior to the then current 2-300 watt peak stereos because the rating on the Fisher was 8 watts continuous across an 8 ohm speaker for an actual output current of 1 amp across the speaker. This was actually higher than the rated peak output on others. As far as I know Fisher was the only maker that ever used actual power output in their ratings. They generated a very stiff power supply by using 65,000 MF filter caps on the positive and negative supplies with a very heavy power transformer. The total voltage across the output IC pacs was around 120V total and the power supply was fused at 5 amps max. So yes it is possible to build a quality system but cheap usually wins out over quality. Gnack |

These unrealistic sounding figures are not always an out and out lie - as such. More the way that they are marketed to the public. For a start, they always use some proprietry "backpedalling peak music with a good following wind into 1 ohm" type power measurement, which results in a figure of 180 watts for a channel based on a car radio output IC, that can actually do about 5 watts RMS on a good day, if you're lucky. Then, they add all the channels together. So if you have an eight channel amplifier, it becomes very easy to reach figures like "1000 watts" ... I recall back in the day, Sir Clive Sinclair bringing out a small IC based power amp, before the public really understood what a chip was. The power output for this thing was claimed at some ridiculous figure like 30 watts. The story goes that this figure had been achieved for 1 second with the thing cooled in liquid nitrogen, or some such nonsense :-) Probably the stuff of urban myth, but the actual amp was, I suspect, capable of no more realistically, than 2 watts RMS.
