AFAIK there are no jumpers to set. Maybe it’s the wrong stationpi. Anyhoo, I’m done reading the manuals. If there are any secrets in there I’m not finding them.
Hello,
I remember asking Doede( dddac designer) about power supply chokes being close to HIS circuit. He told because it is a low impedance circuit the influence of a choke at close distance would be very small. Don't remember his exact words but this is pretty close.
When i first saw the picture i told myself finally someone who decides to reduce cable length between supercaps and consumer.
If the cap is spreading " garbage" why not cover the cap? If the caps are mounted in this " direction " radiation will be in the ok area and if current being consumed is low there won't be that much garbage or not?
Usually carefully designed circuit boards are not that sensitive they say. BUT what about all those wires with different functions all kind of randomly dumped into an enclosure or not even an enclosure creating aerials all over the place. I see them now every day in Ho chi min city.
Greetings,Eduard
P.s WHO told us digital audio is easy???

Hi,
I posted on this thread a bit earlier and have now almost completed my DAC/Streamer project. I ran into one problem related to the LinearPi power:
The setup: Linearpi1 delivers +5VDC and the -5VDC is connected to the +5VDC of the LinearPi2. LinearPi2 delivers -5VDC and, together with LinearPi1 should create 0VDC.
Either LinearPi1 or 2 refuse to light up (power out LED) if the 0VDC cables are connected. Or: If I turn of one LinearPi the other lights up immediately.
Am I thinking something the wrong way? @iancanada is this some kind of electrical short protection?
Thanks for any help, an excellent community, here!

- STATIONPI PRO as a board
- RP 4b
- FifoPi q7
- DUAL MONO MKII DAC ES9038Q2M
- OPA861
- 1x LinearPI (5VDC)for the dirty side and the screen.
- 1x LinearPi (5VDC) for the reclocker and the DAC
- 2x LinearPi (5VDC) for the OPA861

The McFifo / XO clock is in the mail from Audiophonics and I'm trying to figure this out before it arrives.
Today it's, MCH / DAC:
MCK / MCK
BCLK / DCLK
LRCK / D1
data out 1&2 / D2
data out 3&4 / D3
data out 5&6 / D4
data out 7&8 / D5

Looking at your streamer buildup in post 10702. On what platform or basis did you built it?

Searching the article does not find the word 'radiate.' Moreover, inductance can't radiate. Magnetic flux might radiate, but not inductance.
So, what is it you guys read in the article that has you thinking there is a radiation problem?

Hello,
Of course there are also people who are not native English speakers so perhaps they will use the wrong word .
Déjà vu, most Americans cant even pronounce this in a way that a French man will understand it.

Understood. However, the question remains as to whether people should be adding shielding for some reason? If there is no reason, then I guess we should forget the whole thing.
Hello,
Of course it would be nicer if 95 % of the Canadian boards users only encounter minor issues but it seems like there are more than 5,% ending up in trouble.
Some things will be more important than others, as always, but " paying attention" to ten things that could be beneficial while not requiring a financial investment will in the end make you move forward. Maybe just autosuggestion but a lot of high end audio is all about illusion. If you see a pair of coke can caps the proces has already started . Let us just face it.

Yes Edouard,I will also remove the Molex connector from the UcBalancer,So I could weld a cable of 16AWG in place,I have not found any information on the resistance value of the molex connector.
Markw,I had the same reaction as you.But that came from a good feeling from zabloc.
🙂
Hello,
Usually it is not the wire but the connector that is the weakest point. If you check the inside of such a connector you will wonder why you invested this much in a small piece of cable. I think skipping some stages and just solder at least at one side directly at the copper track should be better. Usually a bare solid wire or a multi stranded wite with same diameter could already require a different method of connecting in order to be called a durable,/reliable connection.

Yes, remove the male connector on the UcBalancer board,A solid cable through the hole properly weld will be judicious.
Hi Pete,
I have a good news for you.
Last night, I did a test myself with the same configuration and figured out the issue.
Reason: TransportPi Digi works in master clock mode which needs two additional hardware connections for the clock selection, but the StationPi doesn't provide such connections.
Solution: Solder two wires at back side of the StationPi PCB to connect both pin29 and pin31 between GPIO socket J1 and connector J7, please see the picture.
Result: Works like a charm no longer has any issue
Thank you so much for reporting the issue. Sorry for my late solution. Good luck to your project.
Ian

I am also interested in help regarding this issue. Had identical symptoms when setting up LinearPi Duo for a symmetrical power supply. Then, after a few rounds of trying to get them to work properly and powering up and down, the position of the ON-OFF switches stopped making any difference. Both LinearPi are turned on permanently regardless of the ON-OFF switch position. Power out LED light on one LinearPi is permanently light up, the second one not, but both constantly provide correct voltages at their outputs.
So I have been going over this some more and as far as i2s connections go, I belive I got it right. Please correct me if I'm not, someone.
You can tell me if I'm right as well 🙂

From the McFifo manual I got this:
MCH streamer is also supposed to run as master so I belive this would be the way to do it.
One problem though, it might just as well have been in Latin 😕
