Alpine KTA-200M Compact 200 watts RMS Class D Monoblock Power Pack Amplifier The KTA-200M fits in the open space behind Alpine’s iLX-W670 or iLX-W650 7-inch Mmech-Less (no CD/ DVD) Audio/Video receiver to create Alpine’s unique Power Stack application. The compact footprint of the amplifier (7-inch W x 1.5-inch H x 3.5-inch D) and the shallow chassis of the iLX-W670 (1.9-inch D), occupies the same depth as a traditional 2-DIN chassis, resulting in an easy, hideaway bass solution that adds more power to the sound system without taking up space. The KTA-200M follows the same format as the KTA-450 4-Channel Power Pack Amplifier in a compact size, easy installation, and overall power. While designed to “stack” behind the iLX-W670 iLX-W650, or similar 2-DIN radio, both amplifiers can also be used as standalone solutions in vehicles that don’t have space for a traditional amplifier. The KTA-200M produces 400 watts with Alpine’s DPP technology. During powerful or “dynamic” passages of music, DPP will adapt to the music's needs by adjusting the amplifier's gain and delivering bursts of power that match the peak demands of the music. Alongside that is the new voltage-adapting input circuit to maintain the maximum source signal level without clipping. General Features: Power Stack capable with the Alpine iLX-W670 iLX-W650 compact mono subwoofer amplifier Alpine’s Class D Amplifier Circuit with DPP Dynamic Peak Power (DPP) technology adds a burst of power when needed CTA-2006 compliant 100W x 1 RMS @ 4Ω, Power Outputs 200W x 1 RMS @ 2Ω, Power Outputs 400W x 1 DPP @ 4Ω, Power Outputs Signal to Noise Ratio 85dB (ref. 1W into 4Ω) ≤0.1% THD+N (ref. 10W into 2Ω) Single-side 22-pin connector selectable low-pass filter (60, 80, 120 Hz at 12 dB/octave) preamp and speaker-level inputs RCA inputs (selectable, Low range=0.2-4V) Sound controls; Crossovers-Off/60Hz/80Hz/120Hz Linkwitz Riley LP Filter @ -24dB/Oct.
