WHAT YOU'LL LOVE

ONBOARD TUNING POWER

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

ADVANCED CLASS-D AMPLIFIER DESIGN

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 uses for computers and most handheld devices.

ELIMINATE AUDIBLE NOISES

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

An exclusive protection circuit monitors the amplifier’s thermal condition, adjusting amplifier operation to eliminate annoying shut-down events and keep the music playing.

FULLY CONFIGURABLE OUTPUT CHANNEL

Using the TüN software interface, you may configure the routing, equalization, output level and DRC control functionality.

VXi AMPLIFIER TECHNOLOGIES

JLid PROTOCOL COMMAND

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

DIFFERENTIAL-BALANCED INPUTS

Combating induced cable noise, this technology allows for the use of conventional RCA cables while delivering many of the benefits of a true balanced connection and accepting a wide range of input signal levels.

DSP INSIDE

Powerful DSP technology optimizes each channel’s timing, frequency response and output levels for exceptional sound quality.

NexD2 SWITCHING TECHNOLOGY

Fidelity and efficiency are significantly enhanced by employing new components and more advanced circuit layouts.
