The MB Quart NA3-560.4 is a 560 watt 4-channel marine amplifier. It is waterproof and dustproof, and has marine-specific connectors. It also features top-mounted sound contouring with onboard crossovers, bass boost, and adjustable input sensitivity all concealed behind top-mounted controls. It also uses SMT (Surface Mount Technology) for easier placement and installation. In addition, circuit engineers can design better circuits for power and sound quality as the tolerances of SMT components are superior to larger "through-hole" components. Because of their lower mass, SMT components withstand shock and vibration, making them perfect for audio designed for all vehicles. So use this amplifier in marine, powersports, vehicle, and RV applications.

Details

  • 560 watts max; 140 watts x 4 channels at 2 ohms; 70 watts x 4 channels at 4 ohms
  • Ideal for marine, powersports, and other rugged applications to power 2 or 4 speakers; selectable 2- or 4-channel modes
  • Frequency response: 10 Hz to 45 kHz for faithful sound reproduction
  • Marine-grade IPX standards for waterproofing and dustproofing
  • Nautic gloss-white epoxy finish helps reject heat on the surface of the amplifier; connections from amp are sealed and grommeted; prewired to PC board for additional protection; connector cover should be left closed on RCA jacks that are not used
  • Robust, marine-grade MOSFET Pulse Width Modulation power supply allows amp to product efficient power without taxing the boat's electrical system
  • Utilizes MB Quart's unique Class SQ topology that is matched with Q-Stasis for sonic accuracy and clarity that exceeds standard Class A/B amplifiers
  • FLUID-FETS are painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest-end home amplifiers
  • Auto-sense feature for high-level inputs; variable electronic crossovers allow for complete control of the sound; monitor overload and speaker short protection with illuminated indicators on the amp's end panel
  • DC signal sense switch will allow the amp to turn on when a signal is received on the RCA inputs, so an amp remote turn-on wire is not needed to turn amp on; feature can be turned off
  • SMT (Surface Mount Technology) for larger tolerances from human placement; components withstand shock and vibration making them perfect for audio designed for all vehicles
  • Includes harness, installation hardware, Allen wrench, installation guide, and sticker
