It delivers reference-grade audio amplification with significant energy efficiency while integrating advanced digital signal processing.\n\u003c\/p\u003e\n\n\u003ch3\u003eAudio Performance and Digital Processing\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003cstrong\u003eMV400\/4i\u003c\/strong\u003e provides continuous RMS power of 75 watts x 4 at 4 ohms or 100 watts x 4 at 2 ohms at 14.4V. In bridged mode, it reaches 200 watts x 2 at 4 ohms, for a total power of 400 watts. It is equipped with an integrated 24-bit 96 kHz digital signal processor (DSP), replacing traditional analog settings with software configuration. The frequency response is 12 Hz to 24 kHz (+0, -1dB), with a signal-to-noise ratio of 99 dB (A-weighted, referred to the highest nominal power, analog inputs) and total harmonic distortion (THD+N) below 1% at nominal power. Input sensitivity is 250mV to 16V for analog inputs, with a minimum impedance of 2 ohms unbridged and 4 ohms bridged.\n\u003c\/p\u003e\n\n\u003ch3\u003eConfiguration and Advanced Features\u003c\/h3\u003e\n\u003cp\u003e\n    All amplifier and DSP features are configurable via the JL Audio TüN™ app on an external device (PC, tablet, or smartphone) connected via USB cable or via the Bluetooth® option (with VXi-BTC). The DSP includes input routing and mixing, gain settings with clip indicators, adjustable high-pass, low-pass, and band-pass filters (slopes from 6 to 48 dB\/octave), a 10-band equalizer (graphic or parametric), phase and polarity control, and time alignment in 0.02 ms increments. The balanced differential inputs accept signal levels up to 16V RMS, ensuring excellent noise rejection. Automatic power-on is managed by DC offset or signal detection.\n\u003c\/p\u003e\n\n\u003ch3\u003eMarine Design and Installation\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003cstrong\u003eMV400\/4i\u003c\/strong\u003e amplifier features a compact cast-alloy chassis with high-quality marine-grade epoxy finish, corrosion-resistant hardware, and connectors. It has an IPX2 water resistance rating, meaning it can withstand indirect splashes when mounted vertically with connections facing downward. Dimensions are 52 mm (height), 285 mm (width), and 176 mm (depth), weighing 2.27 kg. Electrical connection requires a minimum 4 AWG power cable. It also includes configurable inputs\/outputs (4 preamp\/speaker inputs and 4 analog preamp outputs processed at 4V RMS) and JLid™ connectivity for optional accessories (such as the Network Hub, Bluetooth Communicator, or digital remote control).\n\u003c\/p\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":56082861228372,"sku":"010-03337-00","price":736.65,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_8991e36e-7bb0-430e-9a0a-b6c4304f70a9.jpg?v=1781188149","url":"https:\/\/skysat.fr\/en-gb\/products\/jl-audio-marine-amplifier-mv400-4i-400w-dsp","provider":"Skysat","version":"1.0","type":"link"}
