$219.99
MB Quart NA4-400.2 Nautic compact 400-watt two-channel powersports amplifier with waterproof potted internals and quick-release connectors.
Compatible Vehicle Fitment | Universal |
|---|---|
Marine Grade Protection / IPX Rating | Meets or exceeds IP67 standards for waterproof and dustproof. Potted Internals: The potting material seals the components, insulating them and ensuring better durability, especially in harsh environments where exposure to moisture or water might otherwise cause short circuits, corrosion, or other performance issues. |
Low Noise Preamplifier Circuit | The highly engineered Q-Stasis pre-amplifier stage reduces incoming noise from source units, dramatically improving sound quality. |
RCA Inputs | 1 pair of high-temperature impact-resistant nickel-plated RCA inputs that allow for secure connections and are corrosion-resistant. |
Operation Mode | Two channel operation |
Crossover Type | Dial Switch OFF / 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 amplifier 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 | Aluminum: Quickly dissipates heat to allow the amplifier to run lower impedance for a 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 Connection Power Wires and RCA Connections. |
Connection Type | Nickel-plated connections: Nickel plated corrosion resistant connections. |
LED System Protection Circuitry Diagnostics | Protection circuits: Monitor thermal, overload, DC, and speaker short protection with lighted indicators on the amplifier end panel. |
