Could you post a picture of the dip switches at the BIII? |

Looks fine. Have you disabled the spdif autodetect function when switching to I2S, by connecting GND to pin 14 (EXT_IO)? |

I checked the Sidecar with B3 with other I2S source (Amanero USB-I2S) a both LEDs (clock & mute) don't lit so no sound, USB-I2S works because F2K see the device & play.

At the end Sidecar plays I2S with Amanero USB-I2S interface, the issue was that Sidecar need the ground of Amanero PSU to works, now I will try to do the same with Teleporters: connect the PSU gnd from Teleporter to GND of the Sidecar & do the same in the transmiter Teleporter

That makes sense. Without a ground reference, the digital signals have an unknown voltage, but almost guaranteed to be too low.

I tried same configuration like the pics posted for Corpius Corpius setupWhen the volume pot of my preamp goes to the maximum I ear a lot of noise but a little bit of music. I tried disconnecting the BIII ground to ground chassis (BIII floating gnd), not fixed still the same issue: I ear a lot of noise but a little bit of music. Transport side the teleporter is grounded with the servo PSU where is coming the I2S signals (2nd file where is connected the input I2S signal to Teleporter emitter) & the Teleporter is powered with is own separate +5VDC PSU mot mixed with servo PSU.

I tested Teleporters switches to know if are configured as transmiter or receiver and both are configured OK.

There is a way to test the Teleporters, measuring voltages or something else?

I supposed that way to see if signals are arriving to Metronome, right?

Thanks, that's a good idea, once measuring why not check the Metronome also.
