This achieves impressive audio performance that fits into many configurations. It is particularly well-suited for smaller vehicles that seek high power in compact installation spaces. With an efficiency of up to 89%, the QM500.4 maximizes energy use, conserving battery power and minimizing heat generation in the vehicle.

What are the dimensions of the ESX Quantum QM500.4?

The compact dimensions of the ESX Quantum QM500.4 Amplifier are 190 x 35 x 112 mm. With this size, the amplifier can be easily accommodated in tight spaces or small compartments, making it ideal for integration into various vehicles. Despite its small size, it features an aluminum heat sink and aluminum die-cast side panels that ensure optimal heat dissipation, thereby ensuring the reliability and longevity of the amplifier. These dimensions allow for flexible installation options without compromising performance.

What filter options does the Quantum QM500.4 Amplifier offer?

The Quantum QM500.4 Amplifier is equipped with a comprehensive set of filter options. It offers high-pass filters (HP) from 50-5000 Hz for channels 1 and 2, as well as adjustable high-pass filters from 10-500 Hz for channels 3 and 4. Additionally, there are low-pass filters (LP) from 50-5000 Hz for channels 3 and 4. These features allow for detailed sound customization based on your preferred audio input and speaker configuration. The Copy mode allows settings from channel 3/4 to be mirrored to channel 1/2, enabling easier adjustment and calibration of the system.

How does the Auto Turn-On function work on the Quantum QM500.4?

The ESX Quantum QM500.4 Amplifier features an Auto Turn-On function that makes it easier and optimizes the activation of the amplifier. This function is activated as soon as an input signal is detected, eliminating the need for a separate remote cable. This feature is particularly useful in vehicles with start/stop systems, where voltage fluctuations can occur. The Auto Turn-On technology ensures that the amplifier operates reliably on every drive, regardless of the voltage fluctuations caused by turning on and off, which can typically occur in modern vehicle systems.

What input options does the Quantum QM500.4 have?

The Quantum QM500.4 Amplifier from ESX offers a variety of input options. It features RCA and high-level inputs, providing high flexibility for integration into existing audio systems. The high-level input is equipped with an Error Protection System that ensures no damage occurs to the amplifier from incorrect signal voltages. With these versatile inputs, the QM500.4 can be connected to both factory radios and aftermarket head units. This guarantees a clean and performance-oriented connection, regardless of the existing system configuration in the vehicle.

What protection mechanisms does the Quantum QM500.4 Amplifier offer?

The QM500.4 from ESX is equipped with a triple protection circuit that guarantees safe operation of the amplifier. The protection mechanisms include overheating protection, short circuit protection, and overvoltage protection, securing the amplifier against unforeseen operating conditions. The implemented MOSFET-PWM power supply architecture also contributes to reducing energy losses and provides stable operating current. These protection features enable a long-lasting and safe sound experience, even in demanding driving situations or at maximum power demands.

Is the Quantum QM500.4 compatible with vehicles from VW and Audi?

While specific compatibility with vehicle models from VW and Audi is not specified, the compact size of the Quantum QM500.4 Amplifier (190 x 35 x 112 mm) allows for easy integration into many vehicles. The high-level inputs support integration into various original systems. Due to the protection and Auto Turn-On functions, this amplifier is also well-suited for modern vehicle technologies, including those from VW and Audi, as it effectively compensates for voltage issues that may arise in these vehicles. Installation in these vehicles should always be aligned with the specific space conditions and electrical requirements.

What is the efficiency of the Quantum QM500.4 Amplifier?

The ESX Quantum QM500.4 Amplifier achieves an impressive efficiency of up to 89%. This is made possible by the use of advanced Class D technology, known for its high efficiency. With this high efficiency, the amplifier significantly reduces energy consumption and minimizes heat generation, which in turn ensures a long lifespan and reliable performance. Especially in vehicles, where energy efficiency and low heat generation are crucial, the QM500.4 is an excellent solution. Accordingly, this amplifier is ideal for environmentally conscious applications without compromising sound quality.

What role does the aluminum heat sink play in the Quantum QM500.4?

The compact aluminum heat sink of the Quantum QM500.4 significantly enhances efficient heat dissipation. This component is crucial for maintaining a constant operating temperature even under high power demands. The use of aluminum allows for optimal distribution and dissipation of the heat generated during operation. This not only improves the overall stability of the amplifier but also significantly extends its lifespan. The aluminum construction contributes greatly to weight reduction, which is particularly advantageous in mobile applications such as vehicles. Additionally, the side aluminum die-cast inserts are dimensionally stable and robust, increasing the overall mechanical integrity of the product.

What functions does the compact bass cable remote control of the QM500.4 offer?

The compact bass cable remote control of the ESX Quantum QM500.4 Amplifier allows precise control of the bass level directly from the driver's seat, without the need to physically access the amplifier. This remote control is perfect for situations where quick adjustments are necessary depending on the music genre or listening environment. The easy accessibility of such a control significantly enhances comfort, especially in active driving situations. Thanks to its compact design, it can be discreetly mounted and does not affect the aesthetic design of the vehicle's interior. This promotes customizable and dynamic sound control.

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
