MB Quart PA1-400.4 Premium Pro 400 watt four channel amplifier designed to produce higher power output in an efficient form factor.

General Features:

• Low Noise Preamplifier Circuit    
  Engineered pre-amplifier stage reduces incoming noise from source units and dramatically improves sound quality.
• RCA Inputs    
  2 pair tiffany style nickel-plated RCA jacks create an efficient connection that is corrosion-resistant.
• High Level Inputs    
  Easily tie into OEM audio systems that do not offer RCA output to maximize after market amplifier power.
• Operation Mode    
  Four channel operation: Flexible installation allows this amplifier to run in four channel or bridged mono mode.
• Crossover Type    
  Switched HPF / FULL / LPF: Complete control of amplifier signal, essential when using two or more amplifiers.
• Class / Topology    
  Full Range Class D: Highly efficient circuit topology which helps the amplifer develop a lot of power in a very small heatsink.
• Output Device Technology    
  PWM MOSFET Power Supply: Stable power through the PC board with minimal heat generation.
• Heat Sink    
  Extruded aluminum heat sink quickly dissapates heat to allow the amplifer to run lower impedance for longer duration.
• Power Supply    
  MOSFET Pulse Width Modulation power supply that allows the amplifier to produce efficient power without taxing the electrical system.
• Output Connections    
  Heavy duty output terminals allows for secure connection so electrical signal can pass into wiring and resist corrosion.
• Connection Type    
  Nickel plated corrosion resistant connections.
• LED System Protection Circuitry Diagnostics    
  Three-stage protection circuits: Monitor thermal, overload, DC, and speaker short protection with lighted indicators on the amplifier end panel.
