Hifonics A1200.4D ALPHA Series 4-Channel Super D-Class Amplifier

1200 watt Hifonics 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.

ALPHA car audio from Hifonics brings together the best design and engineering achievements from nearly 4 decades of driving the advancement of car audio. Technological advances like SUPER D-CLASS® and now FULL RANGE SUPER D-CLASS® have given ALPHA amplifiers the Power From The Gods. The SUPER D-CLASS digital chip technology provides extremely efficient, low temperature, high system power in order to run cool from 4-Ohm to 1-Ohm.

Features:

  • LOW NOISE PREAMPLIFIER CIRCUITRY
    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 on 2 channels
  • 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 onboard 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 that 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
  • CONNECTION TYPE
    Secure connection for all power, ground and speaker connections. Angled for ease of access during installation.
  • LED SYSTEM PROTECTION CIRCUITRY DIAGNOSTICS
    Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel
  • AUTO TURN-ON
    The amplifier detects a voltage rise (6 volts) with a "DC Offset" over the connected input signal on the HIGH-LEVEL INPUTS when the head unit or source unit is switched on. Thus, the amplifier will also be turned on. When the source unit is turn off the amplifier is also turned off. Using this feature eliminates the need to use the REM (turn on the wire)
    The AUTO TURN-ON function will work with 90% of all source units because they are equipped with "high power" output. Only a few older head units will not use this function
  • FULL RANGE DIGITAL
    Mono amplifiers focus on only subwoofer frequencies with Super D Class®, high efficiency/high power technology to deliver maximum wattage. With this focus on engineering, ALPHA delivers big sound while remaining very musical in a compact chassis is the result.
  • SMT INSIDE
    With Surface Mount Technology the typical "through-hole" placement and the larger tolerances from human placement are dramatically improved. In addition, circuit engineers can design better circuits for power and sound quality as the tolerances of SMT components are superior to larger "through-hole" components.
    Because of their lower mass SMT components withstand shock and vibration making them perfect for audio designed for all vehicles.
  • 300KHZ HIGH SPEED PULSING
    The switching speed of the Class D chip puts the amplifier sampling frequencies at over 100 times higher than human ears can hear. This means that the amplifier and the very fast digital switching remain un-hearable in the audio bandwidth for music.
