Good afternoon,
does the nanoAVR-HD or DL has an I2S out connection on the board?
if yes, is it possible to convert that signal to ADAT 8ch with the streamer board?
if yes, there is a delay during this conversion? the i2s output is before or after minidsp processor?
Can I have all channels (7.1)? ...of course using a PCM 7.1 decoded by the source.


My goal is to have a bridge between an home device (i.e. xbox) and a professional device (audio/mixer interface) without a double conversion and without using a preamp ht.

Thanks
Elia

@Elia

Unfortunately we don't have such product in our line up. (HDMI to ADAT) I'm afraid.. :-( Sorry we're not able to help..

I'm aware that the products doesn't exist in your catalog, for this reason I'm asking to you if I can create this solution using the nanoAVR "board" + minidsp.

Thanks,
Elia

Hello,
the nanoAVR HDA's DSP at least does deliver I2S internally to the 8-channel-DAC AK4440.
Cheers, Timo

Thanks Timo!
I compared your image with the only one I found on web about nanoHD

www.avsforum.com/photopost/data/2362538/...3d12d9_DSC04321.jpeg

and it seems different.

The I2S connector, that on your image is near the power, is not present.

Anyway, I think my solution could be feasible using the streamer to convert audio to adat.

Hello,
in my opinion the boards are the same. In the AVSForum you see the nanoAVR, not the nanoAVR-HDA (which I use). So the housing is lower, the DAC board is not present and the related connectors are not needed/assembled.
The firmware may be different also, of course. But I would be surprised, if the I2S data from the DAC would not be routed to the connector anyway.
Cheers, Timo
