Beocreate, Toslink passthru between two boards

Hi Daniel,

I am trying to connect two beocreate boards via the Toslink passthru connector, no sound on the slave board. When changing the optical links around and putting the boards in revers order, same happens: first board plays, second silent.

Is there something simple that I miss here, a passthru jumper or SW setting perhaps? It seems to me that both Toslink terminals on the board are connected back to back without any signal processing, correct? 

The configuration I am using is: foobar on windows 10 laptop, usb to X-SPDIF convertor (Matrix) to Koax-Opto Wandler (Goobay/Wentronic) to Beocreate via Toslink to right beocreate and to left beocreate via Toslink passthru..

Probably a simple issue, but I am out off focus it seems :-)

best regards, Ernest

  Hi,

  the connectors are not directly connected. They are onl connected to the DSP. Therefore you need to create a DSP program that routes the input to the output. Our standard programs don't do this. YOu have to create your own program for this.

  Best regards,

  Thanks Daniel,

  I knew it was too late last night, so I fixed it today in 30 minutes :-). In Sigma Studio go to tab "Hardware Configuration" and sub-tab "IC1 - ADAU145x Register Controls". Then click on S/PDIF TX button in right top corner and select "from SPDIF receiver" in this pop-up window called SPDIFTX INPUT. Then go through the normal "save, link compile download" procedure and store result in the EEPROM of the beocreate board (take off boot jumper, write registers, power off, replace boot jumper and power on again).

  Cheers,
  Ernest

  Thanks for sharing this with us, Ernest. Will order a second Beocreate bord and try it out.
  Cheers,
  Raju

  Am I right assuming, that you get all the audio data through toslink input?

  @ Chris, yes all data is passed transparently this way, no processing by DSP, it is a bit perfect bypass, so you could daisy-chain several speakers in theory, the optical signal is regenerated at every BC.

  sorry for delay, hadn't seen this.
