Digitálny zosilňovač 4x500W, ktorý podporuje nízke a vysoké impedančné zaťaženie
HADA-4B500 je digitálny zosilňovač 4x500W, ktorý podporuje nízke a vysoké impedančné zaťaženie. Interný DSP prostredníctvom softvéru DSP Manager umožňuje prispôsobenie vstupného a výstupného signálu pomocou parametrických EQ, viacpásmových kompresorov, limiterov a delayov a každú konfiguráciu možno uložiť ako predvoľbu. Okrem voliteľného softvéru možno vstupné úrovne ovládať pomocou potenciometrov na prednom paneli, pomocou diaľkových ovládačov GPI na zadnom paneli, alebo cez TCP/IP z riadiacich systémov tretích strán. Všetky zosilňovače série HADA obsahujú účinnú tepelnú ochranu, DC ochranu, nadprúdovú ochranu a HF ochranu pre úplnú spoľahlivosť v akomkoľvek druhu inštalácie.
