Convert Optical (spdif) audio to analog RCA
Is there an inexpensive way to convert optical audio plug to RCA analog
jacks? My PC sound card is optical output only that I can use. I googled it, but there seems to be more analog to optical than vise versa and the ones I found are quite expensive. |

Radio Shack sells one, but their new website is useless for finding anything anymore :-( |

It's called a DAC (digital-to-analog converter). They run from $50 (mostly used) and all the way up. BTW, what do you want to plug it into? Most modern audio devices will handle optical digital input. Kal, even though he mentioned "analog" I read the post to mean an RCA S/PDIF port. |

Convert Optical (spdif) audio to analog RCA
I want to feed mp3s from my PC into my whole house audio system. My
distribution amp (Xantech ZPR68) does not have an optical input. It only has RCA jack inputs. I have a couple of receivers that have optical inputs, but routing through one of those would problem cause issues as those are used for surround sound in 2 of my zones. |

I'll add that though my sound card can feed RCA jacks, the sound is
horrible as there is a lot of interference (when hard drive is spinning, you hear noise, etc.). I was told using the optical connector would avoid this. |

I use my DVD player as a CD/HDCD/MP3 transport and pipe the digital output into my aging Audio Alchemy DITB (modified as per your tweaks plus upgraded op-amp)... works just fine. Really? I stand corrected. I guess I was too influenced by the inability of 'regular' audio DACs to handle DD or DTS. Thanks for the instruction. Kal (who never uses MP3) |

Kal (who never uses MP3) I don't understand why anyone who could buy a good-quality CD or, even better, HDCD, would spend the equivilent amount of money on 128kbps-encoded MP3. The quality just IS NOT THERE. You could buy the CD, rip it to MP3 (for free, at any bitrate you like) to listen to when you're out jogging or whatever you're doing with your mp3 player, and still have the original to listen to in your livingroom. It's a question of quality over quantity I guess... I only used MP3 as an illustration of just another digital bitstream.... that and the fact that my LP walkman keeps skipping when I run ;-) I would put MP3 in the same category with DT and DTS, they all require additional decoding prior to d/a conversion. Does a DD decoder output a 5.1 signal, i.e. do you then need 6 DACs downstream to process? I know zero about home theatre and will probably never have more than two channels.

Does a DD decoder output a 5.1 signal, i.e. do you then need 6 DACs downstream to process? Generally, no, the output is 6 channels of analog signals. However, there are exceptions. Some Meridian processors will output 3xS/PDIF outputs from DD/DTS and a Swiss company will modify some players to do similar. I know zero about home theatre and will probably never have more than two channels. If you live long enough, you might. ;-) Kal |

I googled it, but there seems to be more analog to optical than vise versa and the ones I found are quite expensive. Assuming that you really want to convert S/PDIF optical to stereo analog, Radio Shack used to stock a low cost D-to-A converter, their stock number 15-1242 for under $40. I use it occasionally to convert digital sources to cassette. If you want to convert S/PDIF optical (using Toslink or optical miniplug connectors) to S/PDIF coaxial (using a single RCA connector), the M-Audio CO2 will do the job. It's bit-for-bit accurate, while other similar devices may not be. http://www.core-sound.com/co2/1.php -- Len Moskowitz PDAudio, Binaural Mics, Cables, DPA, M-Audio Core Sound http://www.core-sound.com Teaneck, New Jersey USA Tel: 201-801-0812, FAX: 201-801-0912 |
