Description: Crunch CRA-2000.4 CRA amplifier series features switch mode power supplies that delivers stable and reliable power output regardless of battery voltage. Features & Benefits: Low Noise Preamplifier Circuit Maximum 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 Inputs Highest sound quality connection with quality RCA materials helps prevent interference and minimize distortion in the signal path. High Level Inputs High-level inputs easily tie into OEM audio systems that do not offer RCA output and the Auto Turn-On function simplifies installation. Operation Mode Four Channel Stereo, Dual Stereo Bridged, Stereo + Bridged Mono, Dual Bridged Mono Crossover Type Fully Adjustable 12dB Crossovers Electronic Equalizer Control of amplifier output with on board electronic crossover to tailor specific frequencies to speakers and subwoofers. Class / Topology Very efficient Class D design to drive additional power while remaining a small footprint with lower current consumption. Output Device Technology Proprietary Crunch SPEED-FET MOSFET components maximize the amplifier's power efficiency while improving sound quality and minimizing distortion. Heat Sink Quick Thermal Dispersion Technology assures additional mass in the aluminum heat sink keeps the amplifier running cool. Power Supply Switch Mode Power Supplies - SMPS delivers stable and reliable power output regardless of battery voltage. This prevents power shortages due to insufficient voltage and speaker damage caused by extreme power output due to over voltage. Output Connections Nickel-plated brass connection terminals allow for a secure connection while resisting corrosion. Connection Type Screw Down Connectors: Easy access for hand tool allowing a quick and secure connection. LED System Protection Circuitry Diagnostics Monitor overload and speaker short protection with the lighted indicator on the amplifier end panel.
