MB Quart NA2-500.5, Nautic 5 Channel Compact Powersports Amplifier
Marine Grade Protection / IPX Rating
Amplifiers are ASTM certified which defines that marine amplifiers must use conformal coated PC boards to resist corrosion from salt spray & moisture. IPX5
Low Noise Preamplifier Circuit
Q-Stasis Pre Amplifier Stage: The highly engineered Q-Stasis pre-amplifier stage reduces incoming noise from source units dramatically improving sound quality.
RCA Inputs
2 Pair, RCA (Front/Rear), 1 Pair RCA (Subwoofer) Nickel-Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant.
Operation Mode
Four channel and with dedicated subwoofer channel: Unique design allows this amplifier to power full range speakers with a dedicated channel for a subwoofer.
Crossover Type
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 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 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 Disconnect Wires, RCA Connections: Quickly remove amplifier when you are putting machine up for the winter of as a security precaution.
Connection Type
Nickel-plated connections: Nickel plated corrosion resistant connections.
LED System Protection Circuitry Diagnostics
