JL Audio, an innovator in high-end audio solutions, has unveiled the VXi car amplifier line at their exhibitor booth during the 2018 KnowledgeFest Spring Event in Indianapolis. The VXi amplifier line consists of eight models, all equipped with an integrated Digital Signal Processor (DSP).
JL Audio VP of Electrical Engineering, Dr. Stephen Leigh said: "The VXi project has been in the works for three years and combines the efforts of multiple JL Audio engineering teams 鈥� electrical, DSP, firmware, software, and mechanical. The goal was to deliver true high-fidelity amplifiers with integrated, full-featured DSP tuning capabilities. Our engineering team is thrilled with the end result and we are very excited to be launching these products into the marketplace.鈥�
JL Audio collaborated with AKM鈩�, known for its outstanding digital micro-devices. AKM鈩� created a special configuration of their triple-core DSP, with filter blocks optimized for the VXi鈩� project. Thanks to this powerful DSP, the tuning feature set is robust and flexible, offering the following features on each amplifier channel: signal routing and mixing, parametric equalization, delay in 0.01 ms increments, all-pass filter (phase correction), polarity, and precise level control in 0.1 dB increments. All processing is done at 24 bits/96 kHz.
All tuning and adjustment of the parameters is done via external devices running JL Audio鈥檚 T眉N鈩� software. Accompanying the introduction of VXi is a bundle of software releases, expanding the universe of devices that can be used to control VXi: T眉N 3.0 for PC and Mac OS, T眉N Mobile for Android and iOS Tablets, and T眉N Express for Android and iOS Smartphones. T眉N鈩� 3.0 and T眉N鈩� Mobile offer full control of the entire DSP feature set, while T眉N鈩� Express delivers a simplified experience for quick setups.
VXi amplifiers offer sophisticated and flexible input sections, beginning with differential-balanced, analog input stages with matched gain blocks and high-perforamnce AKM鈩� analog-to-digital converters. Also on-board each amplifier is an optical S/PDIF digital input, capable of receiving up to 24 bit/192 kHz signals. All inputs are configurable and mixable via T眉N鈩� software. VXi amplifiers also provide both analog, and digital, pre-out channels. The analog pre-outs offer a full set of the same powerful DSP features as the amplified channels, permitting the tuning of a second non-DSP amplifier. An optical, digital pre-out at 24 Bit/96 kHz is also provided. This digital pre-out can be level-controlled and equalized, if desired.
VXi also marks the debut of the second generation of JL Audio鈥檚 core Class D amplifier technology, dubbed NexD2鈩�. With NexD2TM the full-range amplifier channels are fed by high-performance AKM鈩� DAC鈥檚 and are fully synchronized by the AKM鈩� DSP, to improve fidelity and audio performance. VXi鈥檚 advanced amplifier designs employ DirectFET鈩� technology and place capacitor banks right at the outputs, greatly reducing loop area to further refine audio quality.
The all-metal chassis design consists of high-quality alloy castings for the main body and bottom panel, with an extruded and machined decorative plate. The LED-lighted logo feature on the top surface can be customized via the T眉N鈩� software.
In addition to the complete lineup of DSP-enabled amplifiers, JL Audio has also introduced several peripheral pieces to simplify the installation process. A BLUETOOTH庐 communicator 鈥� VXi-BTC 鈥� for wireless connectivity from mobile devices, a network hub 鈥� VXi-HUB 鈥� to network up to 5 amplifiers, and a digital remote controller with dual-concentric rotary control, plus push-button preset selection function 鈥� DRC-205.
鈥淭he VXi amplifier lineup has been designed to simplify the process of achieving great audio results by offering control full control of all aspects of system tuning, from one device. We are incredibly excited to release these amazing products and are looking forward to working with our authorized dealers to deliver great audio experiences to our customers.鈥� said Manville Smith, VP of Marketing.
