JL Audio VX800/8i VXi Series 8 Channel Full Range Amplifier DSP Amp 800w RMS

The JL Audio VX800/8i is an 8-channel Class D full-range amplifier with integrated DSP, rated at 800 W RMS total — delivering 75 W RMS x 8 @ 4 Ω or 100 W RMS x 8 @ 2 Ω (14.4 V). It is part of JL Audio's VXi Series, designed for fully active multi-way car audio systems tuned via JL Audio's TüN software.

Part of the VXi range; several VXi amplifiers can be networked with the VXi-HUB (sold separately). For six channels, see the VX600/6i.

TüN™ Software Applications

TüN™ is free to download for computers and most handheld devices. It automatically recognises the connected amplifier and displays the appropriate interface for intuitive setup and tuning.

Unprecedented, Onboard DSP Tuning Power

• Premium, triple-core AKM® DSP with an optimised configuration, 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 & 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

• Second-generation NexD2™ high-speed switching technology delivers full-range power, fidelity and efficiency.
• Reduced loop area design utilises DirectFET™ outputs for very low noise and outstanding fidelity.
• DSP acts as a central clock for all channels to improve audio quality and reduce noise.

Ultra-Versatile Analogue and Digital Inputs

• High-performance, differential-balanced analogue inputs for outstanding noise rejection.
• Accepts speaker-level signals from 200 mV up to 16 V RMS, including signals from many factory systems.
• Optical Digital (Toslink) input for direct S/PDIF connection, bypassing the A/D converter; accepts up to 24 bit/192 kHz.
• Independently configurable RCA analogue and digital pre-outs (24 bit/96 kHz).
• Automatic turn-on via Signal-Sensing or DC-Offset sensing.

Functional Compact Chassis Design

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

JLid™ System Command and Control with Networking Capabilities

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

• 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 compatible Apple® or Android® devices.
• VXi-HUB Optical Network Hub: connects up to five slave VXi amplifiers, synchronising DRC controllers and DSP presets. Up to two VXi-HUBs can be daisy-chained to network up to ten VXi amplifiers.
