toslink to xlr??
I've got an optical output on my USB sound card. I want to connect it to
two Behringer DCX-2496 crossovers, that have "AES/EBU" inputs which have an XLR connection. So the problem is threefold: 1) I have to "convert" the optical output to a coaxial 2) I have to adapt the coaxial to an XLR connection 3) I have to split it to two pieces Are there any devices that do this for me? I need to keep the USB sound card because my application calls for the sound card being powered off the USB port. |

If you want to make something yourself, you can go directly from Toslink optical to AES/EBU. The info needed to do this is here... http://www.epanorama.net/documents/audio/spdif.html I'd guess that it would cost much less than $20 Dunno if you can buy something off the shelf to do this, but if you can, I'd expect it to cost significantly more than your sound card. |

They need power though, which maybe makes your requirement for a USB-powered audio interface irrelevant? Have you tried an analogue audio connection? Can you REALLY hear the difference? |

which maybe makes your requirement for a USB-powered audio interface irrelevant? Have you tried an analogue audio connection? Can you REALLY hear the difference? I don't know. I'm guessing the difference would probably be negligible. But I wanted to stick with the digital output because I'll basically have 4 pieces in the chain, and remaining digital through three of them will make it more immune to noise and ground loops and whatever else in a noisy car. It'll also allow me to skip an extra stage of D/A - A/D conversion. |

As I said, the difference is probably negligible. That is, until you have to start competing with ground loops and the like between the different devices, which by necessity are all powered and grounded at different spots. I have, in fact, tested this notion by running the unbalanced analog output directly from the sound blaster device (powered by the USB port) to the amplifiers, and voila, alternator whine. With this setup, eliminating the noise isn't trivial. So, sticking with the digital output, routing it to a pair of crossovers (run off a power inverter) while staying digital until the last moment - running balanced analog outputs to the amplifiers - gives me no noise at all. Basically, all the pieces involved are capable of digital in/out, so I figured the car would be the ideal place to make use of the capability. |

With this setup, eliminating the noise isn't trivial. How about putting some good quality audio signal isolation transformers on the line... Those break the ground loop nicely. Or using balanced interface. So, sticking with the digital output, routing it to a pair of crossovers (run off a power inverter) while staying digital until the last moment - running balanced analog outputs to the amplifiers - gives me no noise at all. This is a good approach.
