Hi,
i tryed to wire up the adafruit amplifier MAX98306 for a portable audio project.
Do I need to use shielded wire for that?
I used this guidance: https://cdn-learn.adafruit.com/download ... lifier.pdf
But the wiring is still confusing to me.
What exactly means single-ended and/or differential signal.
the single-ended L+ to L+ , L- to GND etc. seems to me like the wiring for stereo.
But the differential doesn't seem so much to be mono.
How would I wire the system up for a mono input. There will be only one plus in, either L+ or R+ - not both of them, right?
Here on page 12 is a grey circle with a green circle in it on the fritzing-sketch. Is this the battery? What is the orange wire?
It would be so nice if anybody could help with the wiring.

You don't have to. If it's in an area with a lot of EMI, I would consider using some, but it should still work without shielded wireDo I need to use shielded wire for that?
Single-ended means there is one pin for left, one pin for right and one common pin for GND.What exactly means single-ended and/or differential signal.
Differential, usually called balanced nowadays, has a L+, L-, R+, R-. Audiophiles believe that it makes the audio clearer and gives more stereo separation. Personally I prefer balanced for hifi stuff, but in terms of actual sound quality, it's really not much of a difference.
They're both stereo.
I think you'd probably connect the positive end (the tip if you're using a TS cable) to R+ and L+, and the GND end to R- and L-.How would I wire the system up for a mono input. There will be only one plus in, either L+ or R+ - not both of them, right?

The orange wire powers the LED.
