ONBOARD TUNING POWER

Each MVi marine amplifier is packed with a complete package of DSP functions, including equalizer, delay, crossover signal routing, mixing and more.

NexD2™ TECHNOLOGY-EQUIPPED

Innovative, high-speed switching design synchronizes an amplifier’s power supply and output channels, resulting in top-flight fidelity with ultralow noise and distortion.

NO KNOBS AND SWITCHES

TüN® is free software from JL Audio that is used to make all setup and audio adjustments. It’s available for download in a variety of applications for computers and most handheld devices.

DIFFERENTIAL-BALANCED INPUTS

A versatile design accepts speaker level signals without a line-output converter; it also delivers outstanding noise rejection while preventing alternator whine and other noises.

ADVANCED ROLLBACK PROTECTION

Innovative circuit design ensures that the amplifier will never shut down as a result of thermal overload and keeps the music playing, even under the most demanding conditions.

JLid™ PROTOCOL COMMAND

This proprietary JL Audio protocol provides easy control and communication of all settings for MVi amplifiers and optional JLid accessories.
