rezerva signala
Explanation:

headroom: The amount of additional signal above the nominal input level that can be sent into or out of an electronic device before clipping distortion occurs.

– Rezerva signala (headroom) za sve komponente ne mora biti jednaka – mogućnost izobličenja
– Moramo smanjiti razinu ispod “jediničnog” pojačanja
-
Potrebna rezerva (headroom)
• Za govor = 10 dB
• Za glazbu = 20 dB
-
– Lp – prosječna glasnoća na udaljenosti D2
– H – rezerva (headroom) u dB
– Ls – osjetljivost zvučnika – razina na 1m pri 1W
– D2 – udaljenost do najdaljeg slušatelja

Muzička se snaga zato kod kvalitetnijih uređaja danas sve češće iskazuje preko podatka za dynamic headroom. Kolika je dinamička rezerva pojačala saznaje se kad se razlika između vršne i trajne snage izrazi u dB. Tako, ako pojačalo ima vršnu snagu od 22 dBW (150 W), a trajnu od 20 dBW (100 W) onda je njegova dinamička rezerva 2 dB. Što je veći broj, dakle, to bolje.
