What are the different inputs / outputs on the mixer (line / phone / AMP / tape)?

I have a small (old, therefore no manual) mixer - and so I wanted to ask if someone can help me understand the inputs / outputs…

For the inputs I have for both inputs (1 + 2)

2 Mail Chinc (R + L) = Line
2 Mail Chinc (R + L) = Phone

And you can switch between the two.

At the exit I have:

2 times Chinc (R + L): AMP
2 times chinc (R + L): tape

You can't switch the output.

What is the difference in each case at the entrance - when do I connect something to the line and when to the phone? (e.g. Laptop, CD player, other mixer, …)

And at the exit, which one can I connect somewhere else? So e.g. On the PC audio input, in another mixer, …

The "Phone" input will almost certainly be a "Phono" input.

Turntables must be operated at this connection; a
