General Features:

  • 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    
    Nickel-Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant.
  • High Level Inputs    
    See Auto-Sense Feature.
  • Operation Mode

    Class Q1 Mono (Class D): MB Quart’s Class Q1 offers the efficiency of today’s D-Class with increased engineering to focus on sound quality from the power supply through the output devices, the FLUID-FETS.
  • Output Device Technology    
    FLUID-FETS: 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    
    Aluminum: Quickly dissipates heat to allow the amplifier to run lower impedance for longer duration.
  • Power Supply    
    Rugged MOSFET Pulse Width Modulation power supply: Allows amplifier to produce efficient power without taxing the vehicle electrical system.
  • Output Connections    
    Heavy duty connections allow for secure electrical signal to pass into wiring and resist erosion which will add longevity to the amplifier.
  • Connection Type    
    Secure connection for all power, ground and speaker connections.
  • Bass Remote Included    
    Included: Wired Bass Remote allows adjustments to bass frequencies to be made from the control mounted anywhere in the vehicle.
  • Auto Turn-On    
    DC SIGNAL SENSE: The DC SIGNAL SENSE switch will allow the amp to turn on when a signal is received on the RCA inputs, so an amplifier remote turn on wire is not needed to turn on the amplifier. This feature can also be turned off.
