AMPLIFIER STATUS INDICATOR LIGHTS & PROTECTION CIRCUITRY

There are two status indicator lights on the input / control end of the amplifier.

1)“Power” (Green): lights to indicate that the amplifier is turned on and operating normally.

2)“Protect” (Red): Indicates that the amplifier protection circuitry has been activated to prevent product failure due to a short-circuit or a dangerously low impedance connected to the amplifier output(s). Connecting the speaker outputs to an impedance lower than 2 ohms will cause this protection mode to activate. When this protection mode is activated, the amplifier will reduce it maximum power output to protect its circuitry, which will manifest itself as increased distortion. When the problem is corrected, the amplifier will return to normal operation.

Advanced Rollback Thermal protection

Unlike conventional thermal protection systems, which shut down an amplifier when it overheats, this system protects the amplifier by gradually reducing power output if the amplifier’s safe operating temperature is exceeded. The amplifier will continue to operate and return

to normal power output once its temperature returns to a normal range.

Low-Voltage protection:

If the car’s supply voltage drops below 10 volts, the entire amplifier will shut itself off to protect its internal circuitry. The green “Power” indicator will turn off when this occurs. The amplifier will turn back on when voltage climbs back above 10 volts. This may happen in a rapid cycle when bass-heavy program material causes a weak charging system to dip below 10 volts momentarily. If this is happening in your system, turn your audio system off and have your power wiring, ground connections and charging system inspected.

SERVICING YOUR JL AUDIO AMPLIFIER

If your amplifier fails or malfunctions, please return it to your authorized JL Audio dealer so that it may be sent in to JL Audio for service. There are no user serviceable parts or fuses inside the amplifier. The unique nature of the circuitry in the JL Audio amplifiers requires specifically trained service personnel. Do not attempt

to service the amplifier yourself or through unauthorized repair facilities. This will not only void the warranty, but may result in the creation of more problems within the amplifier.

If you have any questions about the installation or setup of the amplifier not covered in this manual, please contact your dealer or technical support.

A1400 specifications

The JL Audio A1400 is a powerful multi-channel amplifier designed to meet the demanding requirements of car audio enthusiasts. Renowned for its exceptional performance and quality, the A1400 is a prime choice for those seeking to enhance their automotive sound experience.

One of the standout features of the A1400 is its Class D amplifier technology. This design not only ensures high efficiency, allowing the amplifier to produce more power without generating excessive heat, but it also reduces the overall weight of the unit. The A1400 is capable of delivering 1400 watts of peak power, making it suitable for driving multiple speakers with ease, whether they are part of a full-range setup or a dedicated subwoofer stage.

The amplifier offers a fully flexible configuration, supporting 4-channel output, which enables users to run it in several different modes: 4-channel, 3-channel, or bridging it to a 2-channel operation for increased power to a pair of subwoofers. This versatility makes the A1400 adaptable for various audio setups, whether it's powering front and rear speakers or providing a rich low-frequency response.

In addition to its powerful output, the A1400 includes advanced technologies like differential balanced inputs, allowing for a clean signal transfer and reduced noise interference from external sources. This feature is particularly beneficial in automotive environments where electronic noise can impact sound quality.

The amplifier also comes equipped with a variable crossover network, enabling users to tailor the audio output to their specific needs. With this functionality, users can adjust the crossover frequency to ensure that each speaker is receiving the appropriate range of frequencies for optimal sound clarity and performance.

Aesthetic considerations have not been overlooked; the JL Audio A1400 is housed in a sleek aluminum and steel chassis designed for durability while also promoting effective heat dissipation. The illuminated JL Audio logo adds a touch of style, making this amplifier visually appealing.

With its outstanding power delivery, flexible configurations, and sophisticated features, the JL Audio A1400 stands out as a reliable and high-performance option for anyone looking to elevate their car audio experience. Whether you're an audiophile or just stepping into the world of high-quality sound systems, the A1400 promises to deliver an audio experience that is both immersive and exhilarating.
