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 Three-stage protection circuits: Monitor thermal, overload, DC, and speaker short protection with lighted indicators on the amplifier end panel. Bass Remote Included Included: Wired Bass Remote allows adjustments to bass frequencies to be made from the control mounted anywhere in the vehicle.
