JL Audio MV1000/5i 5 Channel 1000 Watt Class D Marine Amplifier with Integrated DSP

JL Audio MV1000/5i 5 Channel 1000 Watt Class D Marine Amplifier with Integrated DSP

Engineered to deliver reference-grade audio performance in marine environments, every MVi amplifier unites our cutting-edge NexD2™ switching amplifier technology with an integrated, full-featured digital signal processor.

Equipped with our second-generation NexD2™ technology, the MV1000/5i is capable of powering a complete marine 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 transforms 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 a ultra-compact, cast alloy design with marine-grade powder coat finish and corrosion-resistant hardware.

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), Speaker Output Harnesses (2), Subwoofer Output Harness, 6 ft A/B USB Cable

Technology

Advanced Rollback Protection

Summary:
JL Audio's exclusive Advanced Rollback Protection circuit monitors the amplifier's thermal condition and adjusts amplifier operation to eliminate annoying amplifier shut-down events.

Detailed Information:
Should a JL Audio amplifier equipped with Advanced Rollback Protection reach an unsafe operating temperature, a special circuit rolls back peak power output, without changing gain, until the amplifier cools down to a safe operating temperature. The condition is generally indicated by a red “Thermal” or “Status” LED state. On VXI amplifiers, the LED ring will flash red. Once the amplifier cools down, the circuit restores full peak power output and the indicator reverts to its normal state. The operation of Advanced Rollback Protection is inaudible in most cases, but it ensures that your music keeps on playing, even under the most demanding conditions.

Differential-Balanced Inputs

Summary:
JL Audio’s Differential-Balanced Inputs are engineered to combat induced cable noise, which is a common problem in car and marine audio installations. This technology allows for the use of conventional RCA cables, while delivering many of the benefits of a true balanced connection and accepting a wide range of input signal levels.

Detailed Information:
Today’s vehicles are equipped with sophisticated electronics capable of generating noise and interference that can intrude into the audio path, ruining the listening experience.

Most audio equipment uses single-ended, ground-referenced RCA jacks to receive audio signals. This means that the RCA shield is connected directly to signal ground. This is a simple, cost effective input design that works well for short runs in noise free environments. In noisier environments, this method cannot reject the common mode noise that could be on both RCA conductors (shield and center conductor).

By having more than one chassis-grounded RCA shield on a device, single-ended input designs are also more susceptible to ground loops. If noise is present on both conductors while the shield is connected to ground, the input amplifier will amplify the noise relative to the grounded RCA shield. When there are multiple RCA connections or any other conductors subjected to a magnetic field, this will cause a difference in potential across the RCA loop to be amplified at the grounded RCA as noise (a classic ground loop).

JL Audio’s Differential-Balanced Input circuits measure the center pin of the RCA connection relative to the RCA shield, even when the shield is not connected to ground, and even when the voltages at both conductors are moving relative to ground. Because both the center conductor and the shield see high impedance to ground at the input, a ground loop cannot be formed, as there is no current flow to induce a voltage as noise. This works equally well with differential-balanced, or unbalanced signal sources, making this input architecture compatible with all standard car and marine audio equipment, using standard, unshielded, twisted-pair RCA cables. No special cables are required, unlike the fully balanced connections used in professional audio.

Another benefit of the Differential-Balanced Input design is that it easily accepts low-level and high-level signals from a variety of factory head unit outputs and amplifiers, including single ended “ground referenced” sources, as well as Balanced or Unbalanced “Bridged or BTL” sources. This eliminates the need for Line Output Converters (LOCs) in most installation scenarios.

The obvious question is: “Why don’t all car audio amplifiers use Differential-Balanced Inputs" ” The answer is simple: it costs more. Executing a proper differential-balanced input section requires more components and better quality components than a basic single-ended design, so you generally won’t find them on less expensive amplifiers.

JLid

Summary:
JLid™ is JL Audio's protocol for digital controllers and for communication of settings between devices (not for audio signals).

Detailed Information:
JLid™ offers two-way communication for a range of accessories, including the following:

• Wired System Controllers: DRC-100, DRC-200, DRC-205
• Bluetooth® Communicator: VXi-BTC
• Networking Accessory: VXi-HUB

JL Audio FiX™ and TwK™ processors each feature one “JLid™ Port”, designed for connection of a wired controller.

JL Audio VXi amplifiers offer powerful networking capabilities via JLid™, to deliver single-point control of multiple amplifiers in a system. This allows the user to adjust levels (Volume, Fader, Balance, Zone Level) and to select from multiple DSP presets, across an entire group of networked amplifiers. JL Audio VXi amplifiers each feature separate “JLid™ Control” and “JLid™ Comm” ports. Please refer to the VXi product manual and our Help Center for details.

JLid™ connections are made via standard CAT-5e cables.
