About the A800.4D
Description:
800 watt Hifonics A800.4D ALPHA series compact four channel Super D-Class® car audio amplifier with electronic crossovers utilizing Ultra-Fi MOSFETS for high power and efficiency cooling with minimal distortion.
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
• Nickel plated RCA connectors for audiophile signal quality and maximum signal throughput with minimum distortion and maximum external noise rejection.
Operation Mode
• Flexible installation allows this amplifier to run in four channel or bridged mono mode.
Crossover Type
• Accu-Cross crossovers allow for complete control of the signal directing to all speakers. See specifications section for specific frequencies.
Electronic Equalizer
• Control of amplifier output with on board electronic crossover to tailor specific frequencies to speakers and subwoofers. Check specifications for specific frequencies for this amplifier.
Class / Topology
• Developed over 4 decades of engineering to deliver the highest level of sound quality and power efficiency, Hifonics ALPHA Full Range Super D-Class® circuitry results in lower distortion, higher current efficiencies and while producing less heat than conventional amplifier designs.
Output Device Technology
• The Ultra-Fi™ MOSFET is designed for music production vs just electronics output power. It produces very musical high power with high efficiency for cooling and minimal distortion.
Heat Sink
• Heavy duty aluminum alloy heat-sink efficiently moves heat from the MOSFET where it can be cooled.
Power Supply
• The Twin Turbo Coil PS is a Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices.
Output Connections
• Nickel-plated, high temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant.
