Features

VXi Amplifiers: The JL Audio VXi-series of amplifiers feature advanced technology with built-in digital signal processors. These compact amplifiers pack a lot of power into a small package. Each VXi amplifier is equipped with a customized, triple-core DSP that allows you to tune the amplifier to the exact performance you need. With JL Audio's free TüN software on your computer, tablet, or smartphone, you can configure the amplifier from the driver's seat. Up to six active preset tunings can be stored.

6-channel Amplifier: The VX600/6i 6-channel Class D amplifier that has been optimized for full-range amplification of connected speakers, or for a combination of speakers and subwoofers. It has advanced NexD2 switching amplifier technology to deliver solid performance with high fidelity and efficiency. The amp does not have traditional control knobs and switches for setting up the amplifier. Instead, the input sensitivity, crossover, and polarity settings are configured via the TüN software.

Logo Badge: The included JL Audio logo badge is included in the box, unattached. The badge has an adhesive backing for attaching it according to your installation in any 90° increment. The color of the LED ring around the logo badge can be configured in the TüN software to display the amp's status, audio preset, or a user-defined color.

Digital Signal Processing

DSP: JL Audio's Digital Signal Processing engine, when partnered with the TüN software, gives you an enormous amount of control over the configuration and settings of the amplifier. It is equipped with high-performance A/D and D/A converters, and audio processing for high-resolution 24-bit/96kHz audio files. For some VXi models, the DSP offers a 10-band parametric EQ for each output channel, including pre-outs, Linkwitz-Riley and Butterworth high-pass and low-pass filters, Signal Delay (0.01 millisecond steps), polarity reversal, and output trim levels (in 0.1dB steps).

TüN Software: The free TüN software lets you configure, tune, and control your VXi amplifier from your PC, tablet, or smartphone. The TüN software is available for Windows PC (Windows 7 SP1, 8.1, and 10 / 32-bit or 64-bit) and Apple computers. TüN Mobile is available for iPad and Android tablets, while TüN Express works with iPhone and Android smartphones. The apps are compatible with iOS version 10.0 or later, and Android 4.4 and up. When connected to the VX600/6i, you can make the following adjustments and settings on the application:

• Input Selection: Analog or Digital
• Turn-on Mode: Remote, DC offset, Signal Sense
• Input Mode: 2 Ch / 4 Ch / 6 Ch
• Independent Settings for CH 1&2, CH 3&4, and CH 5&6:
  • Input Type: Stereo or Mono
  • High Pass Filter: Off, 12dB, or 24dB; Cutoff frequency: 20Hz (or LPF frequency) to 20,000Hz
  • Low-pass Filter: Off, 12dB, or 24dB; Cutoff frequency: 20Hz to 20,000Hz (or HPF frequency)
  • Level Setting:
    • Input Level: Min to 11
    • Output Trim: -18.0dB to +12.0dB
  • Mute All: On/Off

Power Output: The VX600/6i power specifications are as follows:

Connections

Power/Ground/Turn-On Terminals: The VX600/6i features a removable plug with C-Clamp terminals for the power, ground, and remote turn-on cables. This allows you to pre-connect the wires to the connector, then plug it into the amplifier. The power connector will accept up to 4-gauge power and ground wire, and 10-18-gauge wire for the remote turn-on. The supplied 3mm and 2.5mm hex wrenches are for tightening/loosening the C-Clamps.

Note: The amplifier is not equipped with a fuse. An external 50-amp AFS, AGU, or MAXI fuse (not included) must be installed on the power wire. If a wiring kit is used which includes a fuse with a value other than 50-amps, the original should be replaced with a 50-amp fuse.

Speaker Output Harness: The JL Audio VX600/6i features a removable ABCDEF Speaker Output Harness with 18" wires.

Analog Input Harness: The amplifier has a 25-pin D-Sub connection for the supplied 14" Analog Input harness. Four loom-covered cables exit the cable's D-Sub connector, with three pairs of stereo female RCA inputs, stereo female RCA preamp outputs (4V max output), the remote turn-on output (+12V) and Valet Preset Toggle lead.

Digital Inputs/Outputs: The amp has optical digital (Toslink) inputs for direct connection of S/PDIF digital sources, bypassing the A/D converter. The input accepts up to 24-bit/192kHz signals. There is also a Toslink optical digital output for sending a digital signal (24-bit/96kHz) to another VXi amplifier.

USB: A Type B USB port is provided for connecting the amp to your computer for interfacing with the TüN software. A 6' Type A to USB-B cable is provided.

RJ-45: Two RJ-45 modular ports are provided on the amplifier for optional accessories:

• JLid-COMM: One RJ-45 port, labeled JLid-COMM, is for the optional VXi-BTC Bluetooth Communicator (for wireless communication with Apple or Android smartphones and tablets), or the optional VXi-HUB Optical Network Hub (for connecting up to five slave VXi amplifiers -- ten with two VXi-HUBs, allowing synchronization of controllers and DSP presets).
• JLid-CTRL: The other RJ-45 port, labeled JLid-CTRL, is for the optional Digital Remote Controller (DRC) connection. The optional DRC-205 digital remote control allows you to conveniently set amplifier levels and DSP presets from the front of the vehicle.

microSD: A microSD port is provided on the front of the amplifier for future expansion.
