Dettafli Loverbass 12K-4
Il Loverbass 12K-4 è un potente amplificatore a 4 canali, in grado di erogare 4000 W RMS per canale. È dotato di un DSP avanzato capace di elaborare completamente il segnale con 2048 tap. Il DSP integrato è equipaggiato con filtri FIR, controllo del fattore di smorzamento, equalizzazione dinamica, ingressi e uscite analogiche, Dante/AES67 e un luminoso display IPS da 4,3” con interfaccia touch capacitiva.
L’amplificatore può essere controllato localmente tramite l’interfaccia del display. Le funzioni integrate includono il richiamo dei preset Loverbass, la regolazione del gain, il delay e il mute, coprendo tutte le esigenze comuni dell’utente finale.
Inoltre, il Loverbass 12K-4 può essere gestito da remoto tramite il software ArmoníaPlus.
