Frequently Asked Questions about M-50.4 MD


What are the dimensions of the M-50.4 MD from Audio System?

The M-50.4 MD from Audio System has compact dimensions of 113 x 38 x 100 mm. Despite its small size, it offers enormous power and efficiency, making it ideal for installations in various vehicle models. Its compact design allows for flexible placement within the vehicle without taking up valuable space. These dimensions make it easy to install the amplifier in tight spaces, which is particularly advantageous for modern vehicles with limited space. Consider the dimensions during the planning phase to ensure optimal integration in the vehicle.

What power does the M-50.4 MD amplifier provide at 4 Ohms?

The M-50.4 MD amplifier from Audio System delivers a power of 4x 50 Watts RMS at 4 Ohms. This output power allows for various speaker systems to be supplied with sufficient signal to ensure clear and powerful audio output. The amplification at 4 Ohms is specifically designed to perfectly serve sound systems with standardized impedance without risking overload. This technical specification ensures efficient energy transfer and minimizes distortion, providing you with clean and dynamic sound reproduction. Perfectly suited for enthusiasts who appreciate high-quality audio playback.

How does the high-level input work on the M-50.4 MD?

The high-level input of the M-50.4 MD allows for direct connection of the amplifier to the high-level speaker outputs of the car radio. This is particularly advantageous if you want to retrofit an audio system without a preamp output. The high-level input captures signals with higher voltage and effectively converts them for amplifier processing, which is considered very flexible for various car audio setups. Combined with signal detection and the automatic power-on feature, it enhances user convenience, as the amplifier automatically activates when a signal is detected.

What functions do the filters offer on the M-50.4 MD?

The M-50.4 MD offers a variety of filters: variable and switchable Subsonic, High Pass (HP), Low Pass (LP), and Band Pass (BP) filters. These allow you to precisely adjust the frequency response to optimize the sound for the speakers and the space in the vehicle. The Subsonic filter removes unwanted low-frequency noises, while HP and LP filters target individual frequency bands. The BP filter combines these functionalities and offers flexible settings for specific audio requirements. The use of these filters is particularly advantageous in customized audio configurations.

What is meant by the full active mode in the M-50.4 MD?

The full active mode of the M-50.4 MD allows the amplifier to be connected directly without passive crossover operation, so that each speaker unit receives its own amplifier channel. This enables more precise control and adjustment of the audio output, ideal for a personalized soundstage. Targeted channel separation improves the clarity and dynamics of the audio output. This mode provides special value for elaborate car Hi-Fi setups, where sound fine-tuning and individual level adjustment of the speakers are paramount. Discover new sound dimensions with this feature.

What advantages does Class-D amplifier technology offer in the M-50.4 MD?

The M-50.4 MD from Audio System utilizes highly efficient Class-D amplifier technology, known for its high energy efficiency and low heat loss. This technology converts input currents directly into output currents with minimal energy loss. As a result, users not only receive powerful sound but also benefit from a longer lifespan of the amplifier and reduced heat generation, making it ideal for use in enclosed or tight installation situations. Furthermore, minimizing thermal effects leads to improved sound stability even at high power levels.

What impedance is recommended for maximum power in the M-50.4 MD?

The M-50.4 MD achieves its maximum power at an impedance of 2 ohms, where it delivers 4x 100 watts RMS. This ability to drive low impedances is particularly beneficial for systems that require high power output, such as powerful Subwoofers or multiple speakers in parallel or series connection. By adjusting the load impedance, you can fully exploit the amplifier's potential and achieve a powerful, detailed audio output that remains stable even at high volume. Optimal if you value loudness and sound fidelity.

Is the M-50.4 MD compatible with modern vehicles?

Thanks to its compact design and flexible connection options, the M-50.4 MD is compatible with a variety of modern vehicles. Its small size allows for installation in almost any type of vehicle, even those with limited space. The built-in high-level input ensures compatibility with most factory radios that output high levels. The amplifier's transmission technology works well with the electronics of modern vehicles, minimizing potential interference signals. Thus, it can also be integrated into vehicles with more complex onboard network structures.

How does the M-50.4 MD simplify installation in the car?

The installation of the M-50.4 MD is significantly simplified by its compact design and intuitive connection options. The clearly structured connections and small size make it easy to fit even in tight spaces within the vehicle. Various filters and the high-level input offer flexibility regarding integration into existing systems. Additionally, the automatic signal detection and power-on function make the installation process and daily operation more user-friendly. Careful planning of the wiring paths helps minimize installation issues.

What technologies are used in the M-50.4 MD?

The M-50.4 MD from Audio System is equipped with SMD technology, a modern manufacturing technology that uses compact and highly efficient electronic components. This technology contributes to higher reliability and improved heat dissipation through the dense arrangement of electronic components. Together with Class-D technology, it ensures low heat generation and high efficiency. The electronic circuits are designed to enable maximum sound quality with minimal distortion. The functions of the variable filters and the automatic power-on mechanism are also based on innovative technological advancements in the audio field.
