JL Audio VX1000/5i 5-Channel Class D Amplifier with DSP

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 VX1000/5i 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 600W @ 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 600W @ 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.

JL Audio VX700/5i 5-Channel Amplifier with DSP

VXi amplifiers combine JL Audio’s advanced amplifier technology with a powerful digital signal processor, all within a compact and beautiful package that is easy to install and offers unprecedented tuning power and flexibility.

At the heart of each VXi amplifier is a customized, triple-core AKM® DSP engine. This powerful DSP not only enables powerful tuning capabilities, but it also helps to improve amplifier audio performance by acting as a master clock for the full-range audio amplifier sections. Further amplifier performance gains have been achieved via minimum loop area output designs, DirectFET® output devices and closely coupled output capacitor banks. The result is a new level of Class D amplifier performance, with outstanding efficiency, reliable power delivery and world-class audio quality.

The triple-core DSP engine has ample power to enable a full suite of powerful signal processing functions. These include powerful input switching, routing and mixing that allow a wide range of sources and configurations. Also included for each amplifier output channel and the analog pre-outs: high pass and low pass filters, delay, all-pass filter, polarity and output level trim. Optical, digital pre-outs feature the ability to EQ and level control the digital stream.

Instead of using traditional control knobs and switches, VXi amplifiers are easily configured from the driver’s seat, using JL Audio’s free TüN™ software on a compatible computer, tablet or smartphone. Users can define up to six active preset tunings that can be called up at the push of a button using one of the compatible DRC controllers (sold separately).

Alpine KTA-450 4-Channel Power Pack Amplifier with PowerStack Capability

Features

TECH SPECS

Award-winning Powerstack Compatibility
The KTA-450 can mount behind select Alpine 2-DIN mech-less head units, like the iLX-W650, using the included bracket. The KTA-450’s recessed harness receptacle allows the wiring to fold between it and the head unit so both products fit in a standard 2-DIN space. This PowerStack design is a 2019 CES Innovation Awards winner and makes the duo one of the most powerful 2-DIN radios available. Exclusive Amplifier Technology, Dynamic Peak Power (DPP)
The KTA-450 features Alpine’s exclusive Dynamic Peak Power (DPP). DPP intelligently adjusts the gain to adapt to musical needs. DPP prevents the KTA-450 from clipping by supplying up to double the power for sudden, dynamic sounds. DPP ensures music sounds the way it should at high volumes and boosts the KTA-450 to 400 watts DPP, doubling its power without increasing its size. Compact Size For Hidden Installation Applications
The KTA-450 measures just 7” W x 3.5” H x 1.25” D. For vehicles that do not have the space for a traditional amplifier, the KTA-450’s small size allows it to be tucked away in hidden areas such as in the glove box or behind the radio. It could even be used in a motorcycle’s saddlebag or on a boat. Simple Installation For Use With Any Radio
Thanks to the efficient power needs of the DPP technology, the KTA-450 does not require a new power supply wire at the battery, so installation is fast using the supplied radio power wires. In addition, the KTA-450 uses a 22-pin power harness with a recessed design on one side, so the cables can be tucked-in for a cleaner, less-bulky installation.

Onboard LED-clipping indicators are also included surrounding each input sensitivity control. This convenient feature lets you set your amplifier’s input sensitivity, quickly and accurately, without special equipment. You will also find a set of buffered, pass-through preamp outputs on-board, so you can pass signals to another amplifier.
