MB Quart Discus DA2-520.4D compact waterproof 520 watt four channel amplifier with top mounted controls, potted internals, and waterproof connectors.

General Features:

• Compatible Vehicle Fitment    
  Universal
• Marine Grade Protection / IPX Rating    
  Meets or exceeds IP67 standards for waterproof and dustproof.
• Low Noise Preamplifier Circuit    
  Q-Stasis Pre Amplifier Stage: Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion.
• RCA Inputs    
  Prewired to PC Board for additional protection. Leave connector cover closed on RCA jacks that are not used.
• Crossover Type    
  Variable electronic crossovers allow for complete control of the sound.
• 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    
  Class D: Highly efficient circuit topology which helps the amplifier develop a lot of power in a compact heatsink.
• Output Device Technology    
  MB Quart output devices, FLUID-FETS are painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest end home amplifiers.
• Heat Sink    
  Heavy duty heat-sink efficiently moves heat from the MOSFET where it can be cooled.
• Power Supply    
  Robust premium grade MOSFET Pulse Width Modulation power supply allows the amplifier to produce efficient power without taxing the electrical system.
• Output Connections    
  Waterproof connectors designed to provide a secure moisture-resistant connection, ensuring reliable signal transmission and preventing corrosion or damage in environments exposed to water or humidity.
• Connection Type    
  Waterproof connectors designed to provide a secure moisture-resistant connection, ensuring reliable signal transmission and preventing corrosion or damage in environments exposed to water or humidity.
• LED System Protection Circuitry Diagnostics    
  Monitor overload and speaker short protection with illuminated indicators on the amplifier top mounted control panel.
• Additional Features    
  Top Mounted Controls: Sound contouring with on-board crossover, bass boost, and adjustable input sensitivity are all concealed behind a sealed, top mounted cover.
