Run it like I stole it, that's funny.

What do you mean the input should be shorted?

When you have no source connected to input
and should make measurements, it is better to put a piece of wire
between + an - of input connector.
You put a 'shortcut' - a short across input terminal.

This will give an 'zero input' signal.
Amplifiers do not always like it, when input jack is unplugged.
The input part can even act as an antenna and so disturb measurments.
