Features:

  • Marine Grade Protection / IPX Rating: Amplifiers are ASTM certified with conformal coated PC boards to resist corrosion from salt spray & moisture. IPX5 rating ensures durability in marine environments.
  • Low Noise Preamplifier Circuit: Q-Stasis Pre Amplifier Stage dramatically reduces incoming noise from source units, enhancing sound quality.
  • RCA Inputs: 1 Pair RCA Nickel-Plated inputs with high-temperature impact resistance and secure hex screw terminals, erosion-resistant for reliable connections.
  • Operation Mode: Two-channel operation offers flexibility for installation, allowing the amplifier to run in two-channel or bridged mono mode.
  • Crossover Type: Switched FULL / LPF / HPF for complete control of amplifier signal, particularly useful when using multiple amplifiers.
  • Class / Topology: Full Range Class D topology ensures high efficiency, enabling the amplifier to develop significant power in a compact heatsink.
  • Output Device Technology: PWM MOSFET Power Supply provides stable power with minimal heat generation.
  • Heat Sink: Aluminum heatsink dissipates heat quickly, allowing the amplifier to operate at lower impedance for extended durations.
  • Power Supply: Simpatico Coil Design with dual coil Pulse Width Modulated power supply maintains constant voltage through Ultra-Fi output devices.
  • Output Connections: Quick Disconnect Wires and RCA Connections facilitate easy removal of the amplifier, useful for seasonal storage or security measures.
  • Connection Type: Nickel-plated connections offer corrosion resistance for longevity.
  • 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 for easy diagnostics.
