What does 'unit noise shot' mean?
Please explain with more detail.

 

[70sanson]

noise shot , blow

noise shot is as tak tak tak ok

I think that the OP simply means to say "shot noise". However, a common term like "hiss" or just "background noise" is probably better when the actual noise source isn't known. Is that right, 70sanson?

NOISE COMING FROM THE PRE , this noise appears as if the speaker broke

 

[Ian Finch]

Your description is too vague to tell us anything. A broken speaker could mean it's silent or makes any of a range of sound effects. If the sound is pulsing, as you say "tak-tak-tak", it could even be "motorboating" or low frequency oscillation. Is it a steady pulsing sound even with no signal input?
