  • Key Specs
    • Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
    • Number Of Channels: 2
    • Bass Boost: Variable (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
    • Low-Pass Crossover: Selectable (Devices with this function allow only audio frequencies below a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
    • Speaker-Level Inputs: true (Also referred to as high-level inputs. Enables the amplifier to receive a sound signal from another device that does not have RCA, or low-level, inputs.)

  • Audio
    • Number Of Channels: 2
    • Minimum Frequency Response: 20 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Maximum Frequency Response: 20 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Signal-to-Noise Ratio (SNR): 90 decibels (The ratio of the desired signal's strength to the level of background noise. A ratio higher than 1:1, which equates to greater than 0 decibels, indicates more signal than noise.)
    • Bass Boost: Variable (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)

Boost the sound output in your motorboat with this 400W MB Quart Nautic two-channel amplifier. The LED system protection circuitry indicates failures for easy identification, and the aluminum heat sink prevents overheating. This MB Quart Nautic two-channel amplifier features a low-noise pre-amplifier circuit to boost sound quality and meets the IPX67 standards to withstand splashes and dust.

  • Low-noise preamplifier circuit: The highly engineered Q-Stasis preamplifier stage reduces incoming noise from source units, dramatically improving sound quality.
  • Nickel-plated RCA inputs: Feature hex screw terminals that allow for secure connections and are erosion-resistant.
  • Full-range Class D: Helps the amplifier develop a lot of power in a small heat sink.
  • PWM MOSFET power supply: Stable power through the PC board with minimal heat generation.
  • Aluminum heat sink: Quickly dissipates heat to allow the amplifier to run lower impedance for longer duration.
  • Nice coil design: The dual-coil pulse-width modulated power supply keeps voltage constant through the Ultra-Fi output devices.
  • Quick-disconnect wires and RCA connections: Quickly remove the amplifier when you are putting the machine up for the winter as a security precaution.
  • 0-12dB bass boost: Lets you add punchy bass to your music.
  • 90dB signal-to-noise ratio: Offers crisp sound.
  • Electronic crossovers: Allow for complete control of the sound.
  • 400W maximum power: Ensures robust audio.
