Arnaldo, hai mai pensato ad un qualcosa di semplicissimo per i **144 DSB** che esca meglio del Quansheng che, pur spacciato come **DSB** è tutt’altro ? Forse si potrebbe pensare di trovare anche qualcuno che lo replichi ---

Niente video da parte mia… Ma in questi giorni ho rispolverato un progetto fermo da mesi nel quale anch’io ho due attenuatori 🙂 Data il range limitato di cui avevo bisogno ho scelto due PE4302 comandati a 3 step 0, 8, 16 e 31 dB di attenuazione. Anzi proprio su un argomento simile apro una discussione. ---
