JL Audio VX700/5i

The JL Audio VX700/5i is a reference-grade 5-channel system amplifier with integrated digital signal processing (DSP). It combines NexD2 high-speed switching technology with a powerful DSP in a compact chassis, delivering 4 x 100 W plus 300 W to the subwoofer at 2 ohms. All setup and tuning is done through the free TüN software, so there are no knobs or switches on the amplifier.

Key Features

Onboard Tuning Power: Equaliser, delay, crossover, signal routing, mixing and more, optimising each channel’s timing, frequency response and output level.
NexD2 Class-D Design: High-speed switching synchronises power supply and output channels for top-flight fidelity with ultralow noise and distortion.
No Knobs and Switches: All setup and audio adjustments are made in the free TüN software for computers and most handheld devices.
Differential-Balanced Inputs: Accept 200 mV – 16 V RMS over conventional RCA cables while combating induced cable noise.
Eliminate Audible Noises: Accepts speaker-level signals without a line-output converter and rejects alternator whine and other noises.
Configurable Output Channel: Analogue or optical output with routing, EQ, level and DRC control set in TüN.
Advanced Rollback Protection: Monitors thermal condition and adjusts operation to avoid shut-down events and keep the music playing.
JLid Protocol & Presets: Up to 6 storable presets with an optional JLid DRC remote (sold separately); 12 V remote, signal sensing or DC offset turn-on; removable power, signal and speaker connectors.
