Autotek MM4020.4

Features:

• LOW NOISE PRE-AMPLIFIER 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
  • RCA inputs and outputs provide the highest sound quality connection
• HI LEVEL INPUTS
  • High level inputs easily tie into OEM audio systems that do not offer RCA output. Molex connector is included
• OPERATION MODE
  • 4 channel operation mode allows either stereo or mono bridged operation
• CROSSOVER TYPE
  • Switched 
  • FULL / LPF / HPF for complete control of amplifier signal which is essential when using two or more amplifiers
• ELECTRONIC EQUALIZER
  • Electronic equalizer provides control of amplifier output with onboard electronic crossover to tailor specific frequencies to speakers and subwoofers
• CLASS / TOPOLOGY
  • Class A/B amplifiers have larger heatsinks with very musical bass
• OUTPUT DEVICE TECHNOLOGY
  • MEAN MACHINE'S ROAD WORTHY™ TCID (Twin Coil Isolation Design) and PRO-FI™ High Speed MOSFETS bring extreme power with high sound quality and minimum distortion levels
• HEAT SINK
  • Heavy-duty aluminum alloy heatsink with illuminated connectors provide a blue wash of light from the heatsink underside
• POWER SUPPLY
  • High energy PWM (Pulse Width Modulated) power supply provides MAXXimum power with minimal electrical impact
• OUTPUT CONNECTIONS
  • Nickel-plated brass connectionwith hex set screw terminals allow for secure connection and resist erosion
• CONNECTION TYPE
  • Angled, Allen Key connectors provide easy access for hand tools allowing a quick and secure connection
• FULL-RANGE RCA OUTPUTS FOR SIGNAL PASS THROUGH
  • Full-range signal pass through output allows additional amplifiers to be run from the "output" RCA connections which minimize the need for additional cables running the length of the vehicle. This can dramatically minimize noise.
• LED SYSTEM PROTECTION CIRCUITRY DIAGNOSTICS
  • Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel
