MB Quart's Nautic line of amplifiers use extreme speed processors, resulting in overall low distortion, for stable, reliable, and audible sound performance while conforming to marine electrical standards. The NUA460 delivers 400 watts maximum power, and can be set up for four-, three-, or two-channel applications.
With pure A/B class amplifier topology, Nautic series amps deliver low-distortion, stable performance. Click here for a larger image

Class A/B MOSFET Amplification
The NUA460 boasts Micro Class A/B amplifier topology for lower distortion, complete with a PWM power supply for solid power regulation, and high speed MOSFET output devices for excellent sound reproduction.
Gold-Plated Connections
The NUA460 features gold-plated power, ground, speaker and RCA connections, for resisting corrosion and delivering a clean signal.
High- and Low-Pass Filters
Dial in the output as appropriate for your system with adjustable hi-pass and lo-pass crossovers, both from 40-250Hz.
Ready for the Marine Environment
Marine gear has an even tougher environment than its automaobile counterpart. To that end, the NUA460's heat sink enclosure, paint, and silk screening are UV and salt water resistant. Marine-grade conformal coated circuit boards are used to resist corrosion from salt spray and moisture. Finally, a non-corrosive brushed aluminum extrusion provides an attractive and durable surface finish.
ABYC Compliant
The American Boat and Yacht Council (ABYC) is a trade organization who set forth voluntary standards for all aspects of boat design and construction. The NUA460 is designed to conform to the group's marine electronic standards.
About MB Quart
Bring the luxuries of home to the open water with German-engineered MB Quart marine audio visual equipment. Founded more than 50 years ago in Obrigheim, Germany, MB Quart has integrated high acoustical clarity, easy-to-use designs and sleek products to evolve into the premier manufacturer of entry-level to high performance marine audio visual systems. In an industry where only the strongest survive, MB Quart established itself early by producing world-class automobile and home audio visual equipment. Rain, nor saltwater or even extreme temperatures will destroy MB Quart products, as each one has already survived stringent tests, replicating years of operation.
