Have you had any issues using a transformer with 9VAC secondary going to LinearPis? What xformer are you using that gives you 3 x 9VAC sec. ?
Hi @weust
What is Position of the S1 switch at each of the linearPi?
Can you control each of linearPi’s individually using the external switch and with the master/slave control cable removed?
Regards Mikkel

@miklau All S1 are in the off position.
Each LinearPi works individually.
When it's not stupidly hot here anymore (it was 32C here today) I will test again.
I have placed the switch wire in J3 of the left LinearPi, the one with open J1.
I also saw I forgot to hook up wires to the HdmiPi Pro, so need to take care of that as well.
AWG15 wire is too thick to have two of them in one connector, so will solder it to the bottom of the FifoPi Q7.
I will feed the HdmiPi Pro with it's own 3.3V wires instead of using the passthrough.

On the MC Dual XO there is a "mute". If I'm reading the manual right it
activates an "auto-mute" function when shorted to ground, is this correct ?

Hello,
I have tested the FemtoMck clocks that come with Q7 II on my transport digi v1 and am pretty happy with the results. Since they are not on sale, I am looking for a third-party equivalent. Has anybody compared them with Crystek or Accusilicon ones? Or any other suggestion except SC-Pure.
Thank you!

Hi @weust
You wrote that the external switch is connected to the left linearPi. Is this correct? If that is the case then you have connected the input control cable to the output of the next linearPi.
You must connect the external switch to the master of the linearPi and then connect the control cable from the output j1 to the input of j4 at the next linearPi.
Or in you case, according to your last picture, move the external switch to the J3 at linearPi at the far right side, since this is the master.
Trying to understand how you connected everything but a bit difficult without a picture with updated connections.
If the above suggestions doesn’t work please upload a new picture?🙂
Thanks for the response! So this effectively says that the default setting of the HdmiPiPro matches the default setting of the Denafrips (Mode 0), which is great as no additional configuration would be needed. I had read somewhere earlier in this thread that someone had co that this was not the case and the settings would need to be changed. This document confirms otherwise n
Just curious about the NOS setting on the DAC: I’m assuming this means that the Denafrips will not (or cannot) do oversampling when connected to the HdmiPiPro. Why would this be? sorry if the answer is obvious, I’m still learning my way.
Interesting, I’ll need to read up on this. So what does the NOS/OS toggle button do, and does it matter what setting it’s on when connected to HdmiPi or do I need to make sure it’s in NOS?
@iancanada, I'm trying to use some older boards of yours, and I can't seem to get them to play nice together. This got me wondering if there might be some electrical incompatible with different combination of different generations of PCBs. My current objective (that doesn't seem to be working) is using the 90348MPi Dual Mono Plus dac, and the latest Transformer IV output stage PCB. I've got data showing up on the MonitorPi Pro, but no audible output.
Are there any compatibility issues with using these two boards?
My testing stack is the following;
PurePI II -> RPi 3 -> Dual Mono Plus -> Transformer IV -> MonitorPi Pro
I'll wait for a response to this question, as the answer might enlighten other issues (maybe compatibility) with combination of older and newer boards. 🙂 I'm trying to reduce my testing stack to the bare minimum to help troubleshoot.

Edit: I just tried this combo with the older ESS control (skinny one) and I have audio. Maybe I'm confused. I thought the MonitorPi Pro supported ESS control functionality? I had ESS Controller enabled on the MonitorPi Pro. Is there another option setting that I'm missing?

yes, been there done that., no joy, sound is "shouty" I'm thinking that the Lifepo batteries that I sourced at retail here in Canada were wrong, they are marked 3.2V 3300Mah....and it seems the ANR26650 is rated #.#v 2500Mah.....I've ordered the recommended ones from China, and now I wait. Ian makes no mention on how difficult these batteries are to source. He should !
Hi Team,
Need clarification being new…
On a Q7 why for stock clocks pin1 bending is not given but for other replacement clocks they are doing so?
Is this mandatory to bend pin 1? If not done what are the challenges or limitations we will be having.
Also do we have any functional difference the way streaming/DAC option works because of this.
Please guide.

I know I'm trying to mix-n-match some of Ian's older and newer generation of boards. Some of which may not be compatible. I seem to be proving that to myself. What I've found... It seems newer generation of boards are not compatible with the original FiFoPi Ultimate. Ian states that in the documentation. It also seems that the MonitorPi Pro will not recognize Ian's 9038MPi Dual Mono Plus dac. Can this be confirmed? The manual states it works with an ESS dac (page 6, #2) of the current docs, but does not call out any incompatible with the Dual Mono Plus specifically. This should work sans any FifoPi. It would be nice to have confirmed that the MonitorPi Pro does not have the same ESS controller electrical(or software) compatibility as the original did and therefore does not support the Dual Mono Plus dac.
@iancanada, can you provide further insight on this topic?
Ian users the same output/input footprint on all his DAC’s and analog stages. So this will work.
Regarding the build in ess controller. Do you get the white dot in the top right corner at the MonitorPi pro? This will indicate that the controller can see the ES9038.
I you don’t have this, try powering your different boards in a different order. Yes this doesn’t make sense but many have had this issue and can sometimes simply be solved by changing some wires. You don’t necessary have to go to the same lengths as Gabster did…

When building my new and 2nd IanCanada DAC I think I tested the MonitorPi pro on the first edition dual mono DAC and I worked. I also believe I tested the dual mono mkii DAC on the old fifopi ultimate; also worked.
I was trying to compare the new and old board to hear any improvement in sound quality and therefore quite sure I came across similar configurations.
