JL AUDIO (VX700/5I) 5-CHANNEL CLASS D SYSTEM AMPLIFIER WITH INTEGRATED DSP, 100 WATTS X 4 @ 2 OHM + 300W X 1 @ 2 OHM - 14.4V OVERVIEW: 5-Channel Class D System Amplifier with Integrated DSP, 75 W x 4 @ 4 Ω + 300 W x 1 @ 2 Ω - 14.4V Designed to simplify great audio, every VXi amplifier combines our advanced NexD2™ switching amplifier technology with an integrated, full-featured digital signal processor. Employing our second generation NexD2™ amplifier technology, the VX700/5i efficiently powers a complete audio system. It can drive four main speakers with 75 W x 4 @ 4 ohms while also powering a subwoofer with up to 300W @ 2 ohms. Bridging the main channels converts it into a very powerful, 3-channel system amplifier with up to 200W x 2 @ 4 ohms on the main channels and 300W @ 2 ohms on the subwoofer channel. The NexD2™ full-range technology in the main channels of 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 subwoofer channel features an optimized low-frequency variant of the NexD2™ technology. The amplifier chassis is ultra-compact, with 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), with the appropriate JL Audio TüN® Software application installed. Amplifier includes: Power Connector (for 4 AWG wire), Analog Input/Pre-Out Harness, Speaker Output Harness, Subwoofer Output Harness, 6 ft A/B USB Cable RATED CONTINUOUS (RMS) POWER @ 14.4 V Main Channels @ 4 Ω : 75 W RMS x 4 Main Channels @ 2 Ω : 100 W RMS x 4 Main Channels - Bridged @ 4Ω : 200 W RMS x 2 Subwoofer Channel @ 4 Ω : 180 W RMS x 1 Subwoofer Channel @ 3 Ω : 240 W RMS x 1 Subwoofer Channel @ 2 Ω : 300 W RMS x 1 Subwoofer Channel @ 1.5 Ω : N/A RATED CONTINUOUS (RMS) POWER @ 12.5 V Main Channels @ 4 Ω : 60 W RMS x 4 Main Channels @ 2 Ω : 90 W RMS x 4 Main Channels - Bridged @ 4Ω : 180 W RMS x 2 Subwoofer Channel @ 4 Ω : 180 W RMS x 1 Subwoofer Channel @ 3 Ω : 240 W RMS x 1 Subwoofer Channel @ 2 Ω : 300 W RMS x 1 Subwoofer Channel @ 1.5 Ω : N/A SPECIFICATIONS: Frequency Response (Main Channels) : 12 Hz - 24 kHz (+0, -1dB) Frequency Response (Subwoofer Channel) : 12 Hz - 1 kHz (+0, -1dB) S/N Ratio, referred to highest rated power (Analog Inputs - Main Channels) : 99 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth) S/N Ratio, referred to highest rated power (Analog Inputs - Subwoofer Channel) : 99 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth) S/N Ratio, referred to 1 W (Analog Inputs - Main Channels) : 80 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth) S/N Ratio, referred to 1 W (Analog Inputs - Subwoofer Channel) : 72 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth) S/N Ratio, referred to highest rated power (Digital Inputs - Main Channels) : 101 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth) S/N Ratio, referred to highest rated power (Digital Inputs - Subwoofer Channel) : 102 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth) S/N Ratio, referred to 1 W (Digital Inputs - Main Channels) : 82 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth) S/N Ratio, referred to 1 W (Digital Inputs - Subwoofer Channel) : 80 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth) Damping Factor @ 4 Ω : >150 / 50 Hz Damping Factor @ 2 Ω : >50 / 50 Hz THD+N @ Rated Power (Main Channels) :
