Alpine KTA-450 4-Channel 200 Watt RMS Power Pack Amplifier Dynamic Peak Power (DPP) Technology The KTA-450 features Alpine’s exclusive DPP technology which intelligently adjusts the gain to automatically adapt to musical needs. DPP prevents the amplifier from clipping music signals by supplying up to double the power to support rhythmic instruments that provide snappy sounds (like a snare drum, trumpet, or high-hat cymbals). During these dynamic musical passages, DPP instantly delivers bursts of power to rise to the peak demands of the music. The DPP technology boosts the KTA-450’s performance to 400 watts DPP, essentially doubling the amplifier’s power without increasing its size. Other Power Pack Amplifiers with the DPP technology are the KTA-30FW and KTA-30MW.
