• VXi 400W 4-channel full-range Class D amplifier with integrated DSP.

Features:

• Class D 4-channel full-range amplifier with integrated DSP, 100W x 4 @ 2 Ω / 75W x 4 @ 4 Ω - 14.4V.
  
• Designed to facilitate great audio reproduction, each VXi amplifier combines JL's advanced NexD2™ switching amplifier technology with an integrated, full-featured digital signal processor.
  
• With JL's second-generation NexD2™ technology, the VX400/4i full-range amplifier outputs up to 75 watts per channel into 4 ohms or 100 watts into 2 ohms. It can also be bridged into 4 ohms, producing up to 200W x 2.
  
• The NexD2™ full-range technology in this amplifier is DSP-driven and features a reduced loop area design that utilizes DirectFET™ outputs for outstanding fidelity, very low noise and exceptional efficiency. The amplifier chassis is ultra-compact, with all connections on one side, greatly simplifying installation in tight spaces.
  
• Instead of traditional control knobs and switches, all amplifier settings and DSP functions are configured via a compatible external device (PC, tablet or smartphone) with the appropriate JL Audio TüN™ software application installed.
  
• Amplifier includes: Power connector (for 4 AWG cable), Analog Input/Pre-Out harness, Speaker Output harness.
