Amplifier plus DSP
The MVi Series marine amplifiers combine their latest amplifier technology with powerful signal processing. JL Audio teamed up with micro-device maker AKM™ to create this customized processor-amp hybrid. They also improved the amp's Class D performance by making the signal path through the amp shorter, placing the output capacitor banks nearer the outputs, and using up-to-date DirectFET® MOSFET output devices, resulting in higher efficiency, reliability, and audio quality.
75 watts RMS by four channels and more
The MV400/4i four-channel amplifier puts out 75 watts RMS per channel and features four additional channels of digital signal processing. You could use this amplifier in bridged, 2-channel mode to power a pair of subwoofers with up to 200 watts RMS each, plus send four processed signals on to a separate 4-channel amp to power more speakers. You can sum and re-route the four input channels, the signals for factory tweeters and woofers for example, using the TüN™ software to produce up to four channels of powered output, plus four processed preamp signals for another amp to handle.
Digital accuracy
The 24-bit 96 kHz processing for each channel includes signal routing and mixing, 10-band parametric EQ, time alignment, high- and low-pass filters, and output level control with 0.1 dB precision. In addition to tuning the audio signal, the processor provides a master clock signal for the Class D amplification, increasing audio accuracy.
Remote control only
You make all your settings and adjustments from your compatible device running JL Audio's TüN™ software.
- PC and Mac OS: TüN 3.0 — requires a USB connection (6' cable included with amp)
- Android and iOS tablets: TüN Mobile — requires Bluetooth connection and the VXi-BTC Bluetooth communicator (sold separately)
- Android phones and Apple iPhones: TüN Express (for Basic setups only) — requires Bluetooth connection and the VXi-BTC Bluetooth communicator (sold separately)
Other accessories you may want with this amp
This MVi amplifier features JLid™ inter-device connection ports for JL Audio's proprietary network system for controlling data. The DRC-205 digital remote control and DRCADAPT adapter lets you adjust the master volume, switch between up to six preset tunings, and indicates the amp's status via LED. An optional MVi-HUB marine network hub comes in handy when you have three or more MVi amps in your system, coordinating all the adjustments and controls.
