Authorized MB Quart Dealer!

Features of NA2-400.2:

• MB QUART NA2 400.2 400w 2-Channel Amplifier Amp For Polaris/ATV/UTV/RZR/CART
• Marine Grade Protection: Yes - Amplifiers are ABYC & ASTM certified which defines that marine amplifiers must use conformal coated PC boards to resist corrosion from salt spray & moisture.
  
• Pre-Amp Circuitry: Q-Stasis Pre Amplifier Stage - The highly engineered Q-Stasis pre-amplifier stage reduces incoming noise from source units dramatically improving sound quality
  
• Inputs: 1 Pair, RCA Nickel-Plated - High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant
  
• Operation Mode: Two channel operation - Flexible installation allows this amplifier to run in two channel or bridged mono mode.
  
• Crossover / Signal Shaping: Switched FULL / LPF / HPF - 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 Devices Technology: PWM MOSFET Power Supply - Stable power through the PC board with minimal heat generation
  
• Heat Sink: Aluminum - Quickly dissapates heat to allow the amplifer to run lower impedance for longer duration
  
• Power Supply: Simpatico Coil Design - The dual coil Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices
  
• Output Connections: Quick Dissconect Wires, RCA Connections - Quickly remove amplifer when you are putting machine up for the winter of as a security precaution
  
• Connections Type: Gold-plated connections - Gold-plated power, ground, speaker and RCA corrosion resistant connections
  
• Diagnostics: Three-stage protection circuits - Monitor thermal, overload, DC, and speaker short protection with lighted indicators on the amplifier end panel
  
• Marinized / Waterproof: Yes - Water resistant for durability in any environment
