Description
MB Quart Discus DA2-520.4D compact waterproof 520 watt four channel amplifier with top mounted controls, potted internals, and waterproof connectors.
Fitment: Universal.
Specs: class: Class D; channels: 4 channels; max power: 520W; 2 Ohms power: 4 X 130; 4 Ohms power: 4 X 90; bridged 4 Ohms: 2 x 260; crossover: Electronic; high pass: Switched OFF/HPF/LPF 15Hz-300Hz; low pass: Switched OFF/HPF/LPF 50Hz-300Hz; variable voltage: 0.2V-9V; frequency response: 15Hz-300Hz; fusing: 90A External; power terminal: 4 AWG; speaker terminal: 12 AWG.
Features: marine protection: Meets or exceeds IP67 standards for waterproof and dustproof.; preamplifier: Q-Stasis Pre Amplifier Stage: Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion.; RCA inputs: Prewired to PC Board for additional protection. Leave connector cover closed on RCA jacks that are not used.; crossover type: Variable electronic crossovers allow for complete control of the sound.; equalizer: Control of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers. Check specifications for specific frequencies for this amplifier.; topology: Class D: Highly efficient circuit topology which helps the amplifier develop a lot of power in a compact heatsink.; output device: MB Quart output devices, FLUID-FETS are painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest end home amplifiers.; heat sink: Heavy duty heat-sink efficiently moves heat from the MOSFET where it can be cooled.; power supply: Robust premium grade MOSFET Pulse Width Modulation power supply allows the amplifier to produce efficient power without taxing the electrical system.; additional features: Top Mounted Controls: Sound contouring with on-board crossover, bass boost, and adjustable input sensitivity are all concealed behind a sealed, top mounted cover..
