LM4780 Balanced input confusion

[Xerxes75]

I am rebuilding my Audiosector LM4780 from SE to Balanced input. As I didn't want to mess it up I have taken a good look at the schematic.

While looking at the schematic and some builds on the internet I got confused...
on how to connect Hot, Cold, GND. After searching it only got worse so I taught I ask you about this

Does "Hot" go on the PG- side on the board or the other way around?
And the same question about the output side, which side becomes + and -

I know this sounds very noob, but the confusion got this big that I don't what is right or wrong....I need a drink I guess...

If you're using the Audiosector power supply boards the connections should be obviously labelled. I'm a little worried that you are wiring the mains to the board directly! There's no "hot".

Haha, I am confused but fortunately not that confused. Big Hot, Cold and GND I mean the three leads from my balanced output +,-,GND. The "PG- side" is to indicate the left or right of the PBC.
I am trying to make a drawing to make it more clear but that takes a while..

I am not very good at reading this so I normally use pictures from the internet but that didn't help this time because I see many different ways to connect it and no conclusive text if that what I see in the picture is right.

Use the green components/connections and remove the red. Input pin1 connects to chassis. Input pins 2 and 3 connect to the two inputs.

Hi Mark, thanks so fa so good but does the order of the two Inputs make a difference? (Left or right on the board...That's my question. And the same goes for the output.... What is the correct order of connect the + and -.

It only matters for the polarity of the output signal. Which is a problem if you have more than one channel.

Ah! That explains it... Thanks.
