@ Thermio

This is my setup, just for you to reference.
Mine is BIII SE ES9018 DAC.

Just hope it helps.

Ian

What a beautiful video. I am trying to build a media player for Jellyfin (see video below) and wondered which parts I would need?

What does the Shield Pi do?

Using your video, I have made a layout using the Transport, FiFo, Station, Linear with Uc Conditioners, and an RPi4 and keeping the height to less than 50mm (moved the capacitors off the Uc Conditioner boards).

Default Thank you Ian.

Thank you Ian,

Is this a synchronized setup? I saw your post previously:

Asynchronous I2S FIFO project, an ultimate weapon to fight the jitter

Which shows your synchronized setup which I used in the previous post indicating:

Sync mode for BIII is:
SW1 (X os off, 0 is on)
X000000X
SW2 (X os off, 0 is on)
X000X000

Can you please confirm that this new picture is for async (or for both asynch and sync)

SW1
0000X000 (X os off, 0 is on)
SW2
00000000 (X os off, 0 is on)

Other than the connections and dip switch settings is there anything else that needs to be done with the conventional BIII and it strident regulators and clock for async mode?

For Sync mode is there any modification other than unpowering the clock on the BIII?

Once I have this understood and working in both modes I will put together a FifoPi/BIII step by step for everyone to be able to refer to.

Many Thanks!

Default One more thing...

Ian, I forgot to ask:

I have observed in both pictures something connected to VDD 1.2v on the BIII. Can you please let us know what this is?

Default BIII SW2 inversion

ON configuring the DIP switches on the BII board according to Ian's photo it turns out our SW2 on the respective BIII boards are mounted differently. I suppose the function is the same despite the different numerical orientation. On is still On etc... Perhaps Russ could weigh in on this. If anyone has a comprehensive connection guide for these two devices assistance would be appreciated.

Hi,

What DAC must I select for Volumio? I use the FIFOPI Q3 and the TRANSPORTPI over HDMI i2s out.

I would also like to know if I need to do something special to connect my Audio-GD R8 DAC with the TransportPi HDMI i2s out.

Default RJ45 in FifoPi I2S out

My goal is to use RJ45 input for Roon Bridge on the RPIII/FifoPi and I2S out to the Buffalo.

Your draft looks great! You did good job. Looking forward to your update.

Good weekend.
