This high output power is supported by the Class-D amplifier circuit, which allows for low distortion and maximum efficiency. The digital technology of this amplifier ensures optimal sound dynamics and minimal distortion, providing outstanding clarity and warmth in the sound profile. Especially if you enjoy listening to music at high volumes, the performance of the EA-M4X will exceed your expectations.

Welche Frequenzweichen-Einstellungen sind beim EA-M4X möglich?

The Emphaser EA-M4X features an integrated, variable crossover that can be used multifunctionally. The crossover can be configured as both a high-pass and a low-pass filter, providing you with flexible options for various acoustic systems. The adjustable range extends from 20 Hz in high-pass to 5000 Hz, and from 50 Hz in low-pass to 5000 Hz, allowing for exceptional versatility in setting up audio applications. This optimally supports individual sound preferences and specific music styles.

Wie wirkt sich der Aluminium-Kühlkörper auf die Performance des EA-M4X aus?

The aluminum heat sink of the Emphaser EA-M4X is a central element for the optimal performance and longevity of the amplifier. Its solid construction and sandblasted surface ensure efficient heat dissipation, preventing the amplifier from overheating under heavy load. The conductivity of aluminum ensures that the generated heat is quickly dissipated, protecting the internal components of the amplifier. This well-thought-out cooling technology allows for sustained high power output without compromising sound quality due to overheating effects.

Wie lässt sich der Emphaser EA-M4X im Auto installieren?

The installation of the Emphaser EA-M4X amplifier in the vehicle is relatively straightforward due to its compact dimensions of 240 x 65 x 185 mm. This size allows for flexible placement in the vehicle, whether in the trunk or under the seat. When installing, it is important to use the encapsulated 35 mm² power terminals, which ensure a safe and stable power supply. Additionally, there are screwed RCA sockets available that ensure reliable connections with the audio sources. Make sure that the amplifier is securely fastened to avoid vibrations and possible cable loosening during driving.

Welche Anschlussmöglichkeiten bietet der Emphaser EA-M4X?

Wie beeinflusst der Dämpfungsfaktor die Klangqualität des EA-M4X?

The Emphaser EA-M4X has a damping factor of over 250 at 4 ohms. This high damping factor ensures that the speaker is tightly controlled, resulting in precise reproduction of low frequencies. A high damping factor positively affects sound quality as it reduces the resonance of the speaker membrane, thus delivering clear and tight bass. This precision in bass reproduction leads to a cleaner overall sound, which is particularly beneficial for bass-heavy music pieces. Thus, you get an authentic and powerful sound experience.

Welche Vorteile bietet die Class-D Technik des EA-M4X?

The Class-D technology in the Emphaser EA-M4X amplifier offers several advantages that make it ideal for high-performance audio systems. Thanks to its high efficiency, this technology converts almost all input energy into output power, resulting in reduced heat losses and decreasing the need for large heat sinks. This allows the amplifier to be built more compactly while still providing high power with low distortion. This technique enables it to be both powerful and energy-efficient, which is particularly advantageous in mobile applications where space-saving design and energy management are crucial.
