I have a Helix DSP.3, which only has an optical input and not a coax input. I have a CD player with coax output, and DAP's mostly have coax output (I think), so I'm looking to see if there's such thing as a coax to optical converter? Or, are there any other ideas out there? I want to get a source to provide the bitstream into the optical input of the DSP.3.

coax to toslink adapter - Google Search

Wish it was as easy as a simple google search. However, the adapters provided in the results require 120V receptacle - these are not for the car. Anything for the car?

Thanks DaveG. I saw those, but they are usb powered to a usb AC power adapter that plugs in the wall. This would be put in the trunk of the car. I guess I could get something like the USB outlet in the below link?

Let me know if this is what you were thinking.

That would work or get a usb hub.

You want a digital bridge not a converter. There are a bunch of them but they don't exactly state that they are for what you want. Topping D10s and Douk Audio U2 both duplicate the digital signal in both directions.

Douk Audio U2 USB Converter XMOS XU208 Digital Interface TOSLINK COAX DSD 192KHz

U2 is a USB to Toslink optical and coaxial converter, suitable for PC computer, notebook, android phone(OTG), set-top box, rock 64, raspberry pi and so on, it can bring better listening experience than PC own sound card

Can't speak for the Douk but the Topping only has usb input and @zak has coax output. How would that work?

True. And the same goes with the Douk Audio unit in the link that was provided. I bought one of the $15 converters from Amazon and will try it out. Should arrive in time for the Holiday weekend, so that I can hook it up and try it out.

My apologies - I misunderstood what was needed. But there's plenty of coax to optical converters on Amazon.
