    I have found several converters that convert a toslink(optical) signal to Coax .............

    What I need is a converter transitions a signal from optical to L/R RCAs for use in a modulator.
    Does this thing exist?

    Yes, it's called a "Dolby Digital Decoder". Some DVD players have them built-in, and most AV receivers have them as well.

    It's more than a simple signal-conversion. That optical data is encoded (kind of like a zip file on your computer). You need some processor to decode the bit-stream into the component 5.1 channels. Then other processing needs to happen to merge the 5.1 channels of sound into simple 2-channel L/R, then more processing needs to convert all this (still in digital form) to analog.

    So you are really looking for a stand-alone Dolby Digital Decoder.

    Some units that do this (without being a full-fledged AV receiver) are:

    Adcom GDD-1
    Pioneer DEQ-P7000 : $336
    Sony SDP-E800 : $1 on EBAY
    Technics SH-AC300 : $85 on EBAY

    And if you hunt around on eBay, you could find a few-years old DD receiver used with L/R pre-outs.

    Good Luck.

    PS: Take a look at the back of your DVD player. Most of these units are DVD/CD players and have ordinary L/R audio jacks for 2-channel music. I think these jacks carry the DVD audio as well.

    Thanks Bob!

    I knew it would be more of a box solution (converter) as opposed to an adapter plug, i.e. toslink on one end and RCAs on the other.
