Optical-to-RCA Converter
Hello, all. As this is my first post to the ng I apologize if my gear
is not quite high-end enough. I have a 20-year old Adcom GTP-500 II/GFA-545 II tuner/preamp/amp combination feeding a pair of Allison AL-120 speakers (recently had the woofers refoamed). I would like to connect the optical audio output from a Panasonic TCL32X5 TV to the Adcom tuner/preamp. There appears to be many devices in varying price ranges ($20 and up) to accomplish this. Can anyone provide some experience and recommendations in order that I get the highest quality digital-analog-conversion possible? I'm not looking for overkill, just to match things up to my existing components. Thanks for your time and comment. Sincerely, -- J. B. Wood e-mail: |

Wood e-mail: Before I can answer that, I need some clarification. Is this optical output analog or digital? If it's digital, any number of DACs on the market, in all price ranges are likely to have an optical digital input and RCA analog left and right stereo out. OTOH, if that TV optical output is analog, I don't know what to tell you. There were some products in the late 80's that tried to replace regular audio interconnects with fiber optical, but it didn't take. I haven't seen any equipment with that capability for decades and I've certainly seen no converter boxes that would turn the optical stereo back into electrical stereo. |

Thanks for the quick reply, Empire. Clarification(?) from the Panasonic TC32X5 manual: When an ATSC channel is selected, the output from the DIGITAL AUDIO OUT jack will be Dolby Digital. When an NTSC channel is selected, the output will be PCM. When playing a movie on SD Card Movie player, when the sound has been recorded in Dolby Digital, the output from the DIGITAL AUDIO OUT terminal will be Dolby Digital. When the sound is recorded in other formats, the output will be PCM. Sincerely, -- J. B. Wood e-mail: |

Here's a=20 link to one on E-Bay: http://tinyurl.com/bs2g2jl It is more than adequate for your purposes, has an Optical TosLink input (which is what your Panasonic most likely is) and electronic stereo audio out and, it's less that $22.=20 Do you also need a TosLink cable to go betwen the TV and your new DAC? Try these folks: http://www.mycablemart.com/store/car...ct_list&c=3D11 Their Toslink Cables are excellent and cheap (I use 'em myself). Just buy t= he length you need. Good luck on your project. |

I don't know what I was thinking when I posted that. Because of the several different audio-for-video formats that the Panasonic will handle, you need to understand that the DAC i pointed you to will only decode PCM. It won't work for Dolby Digital, DTS, or other formats. What you need to ensure that the DAC will handle any digital format thrown at it, you would need an audio-for-video decoder. Now, most ver-the air TV sound is PCM (and even analog Dolby pro-logic is broadcast as PCM) so you should be fine, but I wanted to warn you that if you do encounter broadcast (or cable/satellite) in one of the other formats, this $22 DAC will not be able to parse them. |
