Overview

Every VXi amplifier combines JL Audio's NexD2™ switching amplifier technology with a fully integrated digital signal processor. The VX600/6i outputs up to 75 W per channel into 4 Ω, 100 W into 2 Ω, or 200 W x 3 bridged into 4 Ω. The NexD2™ technology is DSP-controlled and uses a reduced loop area design with DirectFET™ outputs for low noise and high efficiency. The ultra-compact chassis places all connections on one side to simplify installation in tight spaces.

All amplifier adjustments and DSP functions are configured via JL Audio TüN™ software on a compatible PC, tablet or smartphone — there are no traditional control knobs or switches.

TüN™ Software

TüN™ automatically recognises the connected amplifier and displays the appropriate interface. It is available as a free download for computers and most handheld devices.

Onboard DSP

• Premium triple-core AKM® DSP, developed in collaboration with AKM®
• Hi-Res audio processing at 24 bit/96 kHz
• High-performance AKM® A/D and D/A converters
• 10 bands of fully parametric EQ per output channel, including pre-outs
• Shelving EQ option for Band 1 and Band 10
• High-Pass and Low-Pass Filters per output channel with selectable alignments and slopes:
• Linkwitz-Riley: 12, 24, 48 dB/octave
• Butterworth: 6, 12, 18, 24, 36, 48 dB/octave
• Signal Delay in 0.01 millisecond steps (equivalent to 1/8 inch / 3 mm)
• All-Pass Filter (Phase EQ) with variable Q and corner frequency
• Polarity Reversal (0 or 180 deg.)
• Output Level Trim in 0.1 dB steps

NexD2™ Switching Amplifier Technology

• Latest-generation high-speed switching technology delivers full-range power, fidelity and efficiency.
• DSP acts as a central clock for all channels to improve audio quality and reduce noise.

Inputs and Outputs

High-performance differential-balanced analogue inputs accept speaker-level signals from 200 mV up to 16 V RMS, including signals from many factory head units. An optical digital Toslink input allows direct connection of S/PDIF sources, bypassing the A/D converter, and accepts up to 24 bit/192 kHz. RCA analogue and digital pre-outs (24 bit/96 kHz) are independently configurable. Automatic turn-on is available via Signal-Sensing or DC-Offset sensing.

Chassis Design

• Solid cast alloy main unibody and bottom plate for strong EMI shielding
• All connections use compact mating connectors for a secure fit in tight spaces
• Configurable LED logo ring displays status, audio preset colour code or a user-defined colour
• Logo badge can be oriented in 90-degree increments
• Corner caps conceal mounting holes and hardware

JLid™ Networking and Control

JL Audio's JLid™ digital protocol provides control and communication between VXi amplifiers and optional JLid™ accessories:

• DRC-100 / DRC-200 / DRC-205 Digital Remote Controllers: convenient level and DSP preset control from the driver's seat.
• VXi-BTC Bluetooth® Communicator: wireless configuration of VXi amplifiers via a compatible Apple® or Android® device.
• VXi-HUB Optical Network Hub: connects up to five slave VXi amplifiers for synchronised DRC control and DSP presets. Up to two VXi-HUBs can be daisy-chained to network up to ten VXi amplifiers.
