We just put another 100 PI2AES in the web store.

 

Does the I2s on PI2AES 2.0 output work with Audio-gd?
If yes, what budget cable is recommended? Would Supra HDMI for example work?
Thanks

 

yes. There is a jumper on the board that switches between audio-GD and PS-audio pin outs. The hardware reference manual on the website, defines the usage

 

PI2AES 2.0 jitter plots from our new APX555 have been posted along with Mercury V3.

Hi all,
Glad I found this forum since considering getting the Mercury. My current streamer doesn’t have i2s outputs.
Basically just need something to stream tidal connect.

 

I've been using an AMB S11 LRPS with the 5V mod for my Pi2 for a while. No issues. Today I built a Noise Nuke to try. Everything is wired correctly and there is 24VDC coming from the Nuke. When I fire it up the lights on the Pi2 flash. Anyone here know what's up with that?

I'm using the stock Meanwell brick.

 

If you used a 5v supply before you needed to remove a jumper to enable external power.

Did you put the jumper back?

 

Without putting that jumper back in you might have fried the MOSFET regulators on the Pi.

 

I went back to the 5V mod and it works fine. I've been searching this thread for the 5V mod post but haven't found it yet.

I just tried the Meanwell by itself and no flashing. ?????

 

I think I need to clear this up. I'm using 5V to power both the RPi and Pi2 together. Simply added a DC jack and connected it to the 5V and G pins (2nd and 3rd pins from the left at the top of the Pi2). I'm not powering the two units separately.

 

probably not

 

Using a Noise Nuke after the cheap Jameco 24V/500mA linear wall-wart, no flashing lights.

Never tried the Meanwell PS, only ever done this configuration, same without Noise Nuke, and 24V to the HAT and 5V to the Pi with jumper removed; no issues with any.

Forgive me, but sometimes it happens to even the most technically proficient... Choke on the input side, caps on the output side, right?

 

I think I've discovered the issue. I connected my meter to the Nuke to measure voltage. When I plug into the Pi2, the flashing begins, and the voltage constantly and quickly fluctuates between 8 and 13 volts. It never stabilizes or gets close to 24 volts.

My take is that the stock Meanwell doesn't have enough current to 'charge' the 6800uF caps in the Nuke and start up the Pi2.

However, if I 'charge' the Nuke first, then plug into the Pi2, all is well. I think I saw a post where someone put a switch in their Nuke. That would solve the issue so long as it was between the cap's and the output jack.

Yep.

 

AtomicBob mentioned an issue with the power supply and the Liquid Platinum.

Basically you want the power supply + noise nuke on first before you power the device. Adding an in-line on/off switch would fix it

Thanks. That confirms what I experienced. I Have a switch coming in today. At least I didn't fry anything.

 

FWIW I tried replicating @TheloniuSnoop 's issue by making the connections in the problematic order - my (half-amp) PS going in last - and couldn't. The HAT & Pi powered up fine, connected to the network, etc., no flashing lights.

Something to do with the way the entire chain presents to the PS 'tricking' the Meanwell's very efficient power management into supplying less current than the Pi actually needs to power up, maybe...?

 

Of course you couldn't duplicate it. Weird sh*t only happens to me. I have the market cornered.

 

Question, perhaps about AES standard / capabilities, perhaps about Pi2AES, perhaps about Byggy AES implementation (which we can only know when we know).

Currently am sending HQPlayer upsampled 192 to an NAA attached to a Pi2AES into my Yggdrasil OG. When Byggy comes along, it will be able to take 384. But can AES handle that kind of throughput reliably or am I going to be going back to USB (which I don't want to do)?
