Alpine MRV-F300

MRV-F300 - MONO POWER AMPLIFIERTens of thousands have relied on V-Power amplifiers for dependable, quality power. Now in their fourth generation, V-Power amplifiers carry on this heritage and prove that playing strong never looked our sounded better. Yes, it is possible to improve upon a good thing.Overview Total Max Power: 640 W 75W RMS x 4 (2Ω, 14.4V, ≤1% THD+N) 50W RMS x 4 (4Ω, 14.4V, ≤1% THD+N) Same power in a 40% smaller chassis Evolution to Class D digital platform New snap-on terminal covers for easy installationRaising the BarThe new V-Power products are now Class D digital amplifiers, resulting in a huge efficiency gain versus their predecessors without draining your battery or your pockets. Class-D provides continuous clean power to your speakers, operating at 80% efficiency far greater than conventional Class A or B amplifiers. Translation: Enjoy cleaner bass, even during extreme power demands.Big Power, Small PackageV-Power amplifiers are known for their compact size, but don’t underestimate their power capacity. Although they have a 40% smaller footprint than their predecessors, they produce the same amount of power as before. Get the power you need, even if you have limited installation space.Non Shut-Down DesignEven if you pound your music for a long time, these amps won’t shut down. They use a Thermal Management Processor to make sure the heat level never gets too high. No distortion, no interruptions!Dual Feedback ModulationDual internal error correction technology – which had previously only been available in the PDX and X-Power amplifiers, is now integrated in V-Power mono amplifiers. The audio input signal is analysed, compared, and corrected twice dynamically as the signal is processed through the amplifier. The result is amplifiers with the widest frequency response, higher damping factor, and lowest noise in its class.Exceptionally Simple Sound UpgradeThe V-Power's 4-channel speaker level inputs connect directly to any head unit, without the need for external converters. This makes the V-Power amplifiers ideal for upgrading factory and aftermarket systems. The flush mount controls make for easy installation. The terminal covers conveniently snap-on without the need for additional tools, to protect the wiring connections while creating a clean, finished appearance.Proven PowerEach V-Power amplifier comes with its very own birth-sheet. V-Power amplifiers are tested and documented to show their true actual output.FEATURESInstall Terminal Layout: Two-Sided Integrated Wire and Mounting Screw TerminalsGeneral Amplifier Type: Class-D (Digital) Channel Design: 4/3/2-Channel Power Supply Design: DC-DC PWM Power Supply Power Supply: MOSFET Pre-Amp Stage: Discrete Final Outputs: Power MOSFET Crossover: Variable Lowpass & Highpass Filter Gain Control: Continuously Adjustable Gain Control Bass EQ Remote Turn On: Remote Sensing Function (for Speaker Level Input) Low-impedance Possibility Current Protection: Over-Current, Over-Voltage, Under-Voltage and Thermal Protection Board Circuitry: S.T.A.R.
