crossover
dbx ® crossover 223xs garantisce grandi prestazioni, basso rumore e affidabilità. la straordinaria precisione dei filtri utilizzati consente di indirizzare ai driver solo la corretta parte di spettro e permette così agli amplificatori di funzionare alle massime prestazioni senza distorsioni, garantendo al proprio sistema pa di generare un suono pulito e preciso. ingressi uscite crossover stereo mode mono mode sistema signal-to-noise
