| 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 Nickel-Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant. |
| Operation Mode | Mono operation: Designed to power 1 subwoofer or subwoofer system. |
| Crossover Type | LPF: 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 amplifer 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 dissapates heat to allow the amplifer 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 Dissconect Wires, RCA Connections: Quickly remove amplifer 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. |
