You have to solder several wires to the right edge of the HiFi Shield 2 PCB to use the XLR connector.

Hi Sirs, I'm very happy with the sound of your products: C2 and HiFi Shield 2, but I'd like to install the XLR outputs. For this reason I've 3 questions: first do you sell something that I can buy about these balanced outputs, second with this configuration will I have a real balanced output with double the volts of the single ended outputs, I mean 4V, and third can I power separately my HiFi shield 2.
My best regards
Have a nice week
Alberto

I thought the RCA outputs were 4V.

Hi Sirs,
I appreciated very much your kind reply. I know the j8 7pin on the Shield 2 is the balanced output, sorry but my questions are very clear and precise. Would you be so kind to help me with the right answers or I have to get by on my own.
You wrote in the HiFi Shield 2 description:
6. Balanced(differential signal) audio output soldering pads are available ... which ones ???
I'm looking forward to hearing from you
My best regards
Alberto

Dear Droid, I've understood that you don't want to answer to my simple questions and I don't bore you anymore ...
just let me know if it's possible to power the HiFi Shield 2 separately from the Odroid 2. Do you think it was possible to give me some infos
about this question ???
Sorry again if I bothered you with my 2 posts.
Anyway the items that I own are good sounding products
Have a nice day
Alberto

I don't understand why you felt like that.
I answered for the question about the balanced output sincerely.

I'm guessing he hasn't answered because he can't say since they have never tried to power it externally.

I don't see why it couldn't be assuming you match the power requirement of the device.

Hi Rooted,
I appreciate very much your comment.
You've clearly understood my simple questions and Odroid's empty replies.
In the meantime we wait for one of his exhaustive answer on the subject.
Thanks again, I was almost thinking that I were the real issue.
Regards
Alberto

I have the HiFi shield 2 but don't have a way to test if it can be powered while not connected to the GPIO header since I don't have a 3.3v power supply or any resistors.

Cut the J7 header pin #3 and connect a separated clean 5Volt source to the Shield.

Oh it's 5V, good to know. I guess had I looked at the header I would have known.

Odroid was was saying the input power source should be 5v, not the output. I mentioned 3.3v and odroid corrected me.
