NA3-560.4

Marine-Grade Power for Harsh Environments

The MB Quart NA3-560.4 4-channel marine amplifier is engineered specifically for life on the water. Built with marine-grade protection and IPX water-resistant standards, it is designed to withstand extreme marine conditions, including moisture, humidity, and salt spray. This rugged construction ensures reliable performance so your music never skips a beat, even in demanding environments.

Clean, Low-Noise Audio Performance

Featuring a low-noise preamplifier circuit, the NA3-560.4 maximizes signal strength while minimizing electrical distortion between the amplifier and the source unit. High-tech Fluid FET output devices are carefully selected to deliver efficient power and sound quality comparable to high-end home amplifiers, providing clear, detailed, and powerful audio on the water.

Efficient Cooling and Easy Sound Tuning

The nautical white glossy epoxy finish helps dissipate heat efficiently, allowing the amplifier to cool properly and operate more efficiently over extended periods. Top-mounted controls provide easy access to onboard crossovers, bass boost, and adjustable input sensitivity, while marine-specific RCA inputs are directly connected to the PCB for added durability and protection.
