JL Audio VX600/1i Class D Subwoofer Amplifier with integrated DSP, 600 Watts @ 2 ohm / 400 Watts @ 4 ohm

Amplifier plus DSP We've heard a lot of good things about JL Audio's VXi Series amplifiers, which combine JL Audio's latest amplifier technology with powerful signal processing. They also improved the amp's Class D performance by shortening the signal path through the amp, placing the output capacitor banks nearer the outputs, and using up-to-date DirectFET® MOSFET output devices, resulting in higher efficiency, reliability, and audio quality. 600 watts of bass The VX600/1i mono subwoofer amplifier can put out up to 600 watts RMS for your sub, and features 3 channels of digital signal processing. You could set up a system, for example, by routing the signal from the receiver to this sub amp first, and then sending a processed stereo signal on to a separate amplifier for your other speakers. Digital accuracy The 24-bit 96 kHz processing for each channel includes signal routing and mixing, 10-band parametric EQ, time-alignment, high- and low-pass filters, and output level control with 0.1 dB precision. In addition to tuning the audio signal, the processor provides a master clock signal for the Class D amplification, increasing audio accuracy. Remote control only You make all your settings and adjustments from your compatible device running JL Audio's TüN™ software. PC and Mac OS: TüN 3.0 — requires a USB connection (6' cable included with amp) Android and iOS tablets: TüN Mobile — requires Bluetooth connection and the VXi-BTC Bluetooth communicator (sold separately) Android phones and Apple iPhones: TüN Express (for Basic setups only) — requires Bluetooth connection and the VXi-BTC Bluetooth communicator (sold separately)

• Other accessories you may want with this amp
  This VXi amplifier features JLid™ inter-device connection ports for JL Audio's proprietary network system for controlling data. The DRC-205 digital remote control lets you adjust the master volume, subwoofer level, switch between up to six preset tunings, and indicates the amp's status via LED. An optional VXi-HUB network hub comes in handy when you have three or more VXi amps in your system, coordinating all the adjustments and controls. A FiX 82 or a FiX 86 can be used to remove factory sound processing, for higher-fidelity factory system integration for your VXi amplifier.
