Unbalanced to balanced Q

[gmphadte]

Q-How about not using di box in connecting laptop to audio mixer what about using mini jack to two trs? Is it possible?

Poster1- Sure no problem, but use a minijack to 2xTS cable as shown in the video.

My post
Little confusion...he does not want to use DI box. It should not be done as you will get noise as the unbalanced signal grounds one of the pins of the balanced input.

Poster1- This is correct, however as long as the cable run is under 15m you will generally not have noise issues.

Is poster 1 correct..

A DI box is primarily used to isolate grounding points, thus removing loops.

What I wanted to know is...
In case of a short cable can unbalanced cable be connected to balanced input and have clean sound.

There must not be a great problem doing it properly.

One side of the balanced input will need to be connected to ground and the other input to hot or signal. Yes it will work.
