JL Audio VX400 / 4I: 75 W RMS x 4 4-Channel Car Amplifier
About the JL Audio VX400 / 4I: 75 W RMS x 4 4-Channel Car Amplifier
Unprecedented, onboard DSP tuning power!, 2nd generation NEXD2 switching Amplifier technology, ultra versatile analog and digital inputs / outputs and signal processing, Jlid system command and control through networking capabilities:
Designed to simplify great audio, every VXI Amplifier combines our advanced NEXD2 switching Amplifier technology through an integrated, full featured digital signal processor.
Through our 2nd generation NEXD2 technology, the VX400 / 4I full range Amplifier outputs up to 75 W per channel into 4 ohms, or 100 W into 2 ohms. It can also be bridged into 4 ohms, producing up to 200 W x 2.
The NEXD2 full range technology in this Amplifier is DSP controlled and features a reduced loop area design utilizing directfet outputs for outstanding fidelity, very low noise and exceptional efficiency. The Amplifier chassis is ultra compact, through all connections on one side, to greatly simplify installation into tight spaces.
Instead of traditional control knobs and switches, all Amplifier adjustments and DSP functionality are configured via a compatible external device (PC, tablet or smartphone), through the appropriate JL Audio tun software application installed.
Amplifier includes: power connector (for 4 AWG wire), analog input / preout harness, speaker output harness, 6 FT A / B USB cable
Features:
- Powerful DSP permits optimizing each channel's timing, frequency response and output levels, for exceptional sound quality.
- Tun software delivers fast and easy setup, at your fingertips. Make all adjustments through a clear interface. Free tun software is available for computers and most handheld devices.
- Advanced, high speed switching technology delivers reference grade power and efficiency.
- DSP synchronized power supply and output Channels produce world class sound quality through very low noise and distortion.
- Differential balanced analog inputs accept speaker level signals up to 16 V RMS, including those from factory systems. Delivers outstanding noise rejection to prevent alternator whine and other noises.
- Optical digital (toslink) inputs permit direct connection of S / PDIF digital sources, bypassing A / D converter. Accepts up to 24 bits / 192 kHz input.
- Analog and digital preouts (pass through or fully configurable): RCA preouts (4 V RMS maximum) and optical (toslink) output at 24 bits / 96 kHz
- Automatic turn on options via signal sensing or DC offset sensing
- Proprietary JL Audio protocol provides control interface and all communication for VXI Amplifiers and optional Jlid accessories, including: DRC-100 / DRC-205 (digital remote controllers): offers convenient DSP preset selection and level adjustments from the driver's seat. VXI-BTC Bluetooth communicator: adds wireless connectivity for Amplifier configuration from a compatible IOS or android device. VXi hub optical network hub: provides network connectivity for up to 6 VXI Amplifiers, allowing full system DRC control and preset selection. Up to 2 VXi hubs can be daisy chained to control up to 10 VXI Amplifiers.
