optical Toslink to ST conversion

[Nounours18200]

Hi,

My source has an optical Toslink sound output.
My DAC has ONLY optical ST inputs.

Do you know good Toslink to ST adapters or interfaces ?

Thank you very much

Straight-tip optical uses a completely different transmitter and receiver than optical s/pdif. And I can't find a converter.

It sounds like you have an old DAC - maybe Jadis? But this DAC also has coaxial s/pdif input? If so, get a toslink-coaxial s/pdif converter -
Optical Toslink to Coaxial SPDIF Digital Adapter - Audiophonics
and go from toslink at your source to coaxial s/pdif at the DAC.

It is an old DAC but not a Jadis: it is a beloved WADIA (fully upgraded), which has only ST inputs

so I cannot use a BNC converter...

Do you have another solution ?

Which model Wadia?

Sorry for my late reply, but the reply notification went in my "spams" folder...

It is a Wadia 9 fully upgraded

 

[linuxfan]

Well I just downloaded the manual for the Wadia 9, and I see the officially sanctioned way of connecting s/pdif to the glass optical input of the Wadia 9 is with the addition of a Wadia 10 Glass Optical Interface.
I imagine a Wadia 10 is quite expensive.

Alternatively if you have no further use for an ST optical input, you might consider modifying the Wadia 9 to replace the ST receiver circuit with a conventional s/pdif receiver circuit, such as -

....My source has an optical Toslink sound output.

1. What is this source?


2. What do you use now for the ST input for the ? Wadia 9

 

[Nounours18200]

Sorry for m late reply, but for an unknown reason, I never received a notification of replies...
I am still looking for a solution, or... for a Wadia 10....

Whats the problem....

 

[Nounours18200]

The problem is that my Wadia has only ST inputs, whereas the modern sources have only BNC or Toslink or I2S outputs.
So I cannot connect modern sources to my Wadia 9. A Wadia 10 or a Genesis Digital Lens would be a solution but are very rare.

1. What is this source?

The sources can be Homecinema front channels, a Bluetoofh receiver or anything else. I have found a well designed Switch that has both:

• 3 BNC inputs + 4 Toslink inputs
• 1 BNC output + 1 Toslink output

and I connect all the "non ST" sources to this high quality switch, and therefore the problem is reduced to "how to convert the BNC switch output (*) to ST", in order to use the Wadia.

(*) BNC is obviously better than Toslink, but if I find a solution to convert Toslink to ST, it would be an acceptable approach too.

The "AK4113 Digital Receiver Board SPDIF Optical/Coaxial/I2S Input To I2S Output | eBay", does not seem to be a solution to my eyes, because I still don't see how to feed the Wadia with I2S ? And its RCA inputs of this AK4113 are totally without any interest for me, because I try to build a high quality solution, so RCA should be avoided or replaced by BNC. If they could be replaced by BNC, then OK, but the problem to feed the Wadia remains.

I hope to have clarified the problem, if not please ask.

Would you mod the Wadia DAC internally by removing the ST receiver?

Hi Nounours, there is Wadia 10 which accepts 5 bncs and one tosslink input and output one ST to Wadia 9! problem solved :]
Wadia 10 looks basically the same as Wadia 9’s power supply, and it’s exactly the same size. I have posted a photo of my setup here.

Regards from Germany,

Wadia 9 DAC has 3 high quality ST link inputs, there are DDCs like M2TECH hiFace Evo with ST link output for a cheaper and cleaner solution.
