NEUMANN KH420A ACTIVE STUDIO MONITOR MID-FIELD 3VIE GREY

La KH 420 è il risultato dell'utilizzo delle più revcenti tecnologie di progettazioni acustica, elettronica e meccanica, per portare ad un nuovo livello di riferimento di qualità nella riproduzione audio. Monitor attivo Mid-Field, bass reflex, a 3 vie, triamplificato: 330 +140 + 140 W, ingresso bilanciato elettronicamente, woofer da 10" + midrange da 3" + tweeter da 1" Max SPL 116,4 dB, color grigio.MOnitor particolarmentre adatto per l'uso nella musica, il broadcast e post produzione, per il monitoraggio,la miscelazione e il mastering. E' possibile utilizzarei il KH 420 anche ad incasso ad una parete o nei sistemi multicanale miscelandolo anche con altri prodotti della gamma Newmann
