Description:Autotek SM-1200.4D STREET MACHINE amplifier series with QTD Technology delivers 1200 watts to speakers and features built-in electronic crossovers.Features & Benefits: Low Noise Preamplifier CircuitMaximum low voltage signal from the source unit comes into the amplifier through a low voltage circuit which delivers minimal distortion through the amplification process. RCA InputsHighest sound quality connection with quality RCA materials helps prevent interference and minimize distortion in the signal path. Operation ModeFour Channel Stereo, Dual Stereo Bridged, Stereo + Bridged Mono, Dual Bridged Mono Crossover TypeFully Adjustable 12dB Crossovers Electronic EqualizerControl of amplifier output with on board electronic crossover to tailor specific frequencies to speakers and subwoofers. Class / TopologyClass D: Very efficient Class D design to drive additional power to speaker frequencies while remaining a small footprint Output Device TechnologyPro-Fi™ High Speed MOSFET’s components maximize power efficiency while improving sound quality and minimizing distortion. Heat SinkSound Shield™ Technology assures additional mass in the aluminum heat sink keeps the amplifier running cool while shielding music from distortions that can be caused by heat. Power SupplyHigh energy Pulse Width Modulated Power Supply delivers power with minimal impact on the electrical system. Output ConnectionsNickel Plated Brass Connection with terminals allow for secure connection while resisting corrosion. Connection TypeScrew Down Connectors: Easy access for hand tool allowing a quick and secure connection. LED System Protection Circuitry DiagnosticsMonitor overload and speaker short protection with lighted indicators on the amplifier end panel.
