Descrizione
Il KH 870 risponde alle nuve ersigenze di gestione di più canali offrendo un nuovo 7.1 High Definition Bass Maneger compatibile anche con tutti i formati di consumo standard dal mono fino al più recente 7.1 HD. Otto canali analogici assicurano una interconnettività flessibile per gli studi moderni. Quattro modalità di elaborazione LFE garantisce la compatibilità con tutti i formati. Forth-order crossovers e i controlli acustici flessibili consentono l'integrazione con diversi l sistemi.Le più recenti tecnologie di amplificazione e i componenti acustici utilizzati permettono una riproduzione del suono il più preciso possibile senza distorsioni alle basse frequenze anche ad alti livelli.
