Frequently Asked Questions about A4120

Wie hebt sich der A4120 von Axton als Verstärker ab?

The Axton A4120 is an ultra-compact 4-channel Class-D amplifier that impresses with its specific technical features. The aluminum heat sink ensures efficient heat dissipation, optimally cooling the amplifier. In addition to a RCA input, it has a high-level input with an auto-turn-on function, allowing for flexible installation. Its input sensitivity is adjustable between 0.5 and 6 V. With a damping factor of over 100 Hz at 4 Ohms, it ensures excellent sound reproduction.

Welche Filteroptionen bietet der A4120?

The A4120 from Axton offers adjustable low-pass and high-pass filters, both of which can be set in the range of 50 to 250 Hz. These filters with a slope of 12 dB/octave allow for adjusting the frequency range according to individual preferences, thus achieving optimal sound in the vehicle. The flexible adjustment enables precise control of the sound, making the amplifier versatile, regardless of whether deep bass frequencies or high tones are preferred.

Wie hoch ist die Ausgangsleistung des A4120?

The amplifier A4120 delivers a maximum output power of 4 x 60 W at an impedance of 4 ohms. This power allows for the simultaneous supply of various speakers with sufficient current to ensure a clear and powerful sound. By simultaneously powering four channels, both front and rear speakers are driven, creating a balanced sound image throughout the vehicle's interior.

Wie unterscheiden sich die Eingangsoptionen beim A4120?

The Axton A4120 offers two essential input options: a RCA input and a high-level input. The RCA input is ideal for connecting to modern car radios with corresponding outputs. The high-level input, on the other hand, is designed for direct connection to the speaker outputs of older car radios and features the auto-turn-on function, which automatically activates the amplifier when an audio signal is detected. This allows for flexible integration into various vehicle systems.

Welche Abmessungen hat der Axton A4120?

The dimensions of the Axton A4120 are 196 x 35 x 82 mm (width x height x depth). These compact measurements allow for versatile installation, even in vehicles with limited space. The amplifier can easily be placed under the vehicle seats or in the trunk due to its small size, without taking up much space. The ultra-compact design also facilitates integration into the existing vehicle interior and allows for discreet mounting.

Wie wirkt sich der Frequenzgang des A4120 auf die Soundqualität aus?

With a frequency response of 10 Hz to 30 kHz, the Axton A4120 can process and reproduce a wide range of audio signals. This allows for the reproduction of deep bass frequencies as well as clear highs, resulting in a balanced and detailed sound experience. The large frequency range ensures that no nuance of the audio signal is lost, which is particularly important for music lovers who value the finest sound details.

Wie hoch ist der Signal-Rauschabstand des A4120 und was bedeutet das?

The Axton A4120 has a signal-to-noise ratio of 90 dB, which means that the amplifier is capable of reproducing audio signals with minimal background noise. A high signal-to-noise ratio is essential for sound clarity, as it ensures that the desired sound is more dominant than the background noise. This results in a particularly clear and clean sound image that impresses in both quiet and loud passages.

Welche technischen Vorteile bietet der Aluminium Kühlkörper des A4120?

The aluminum heat sink of the Axton A4120 has been designed to ensure efficient heat dissipation. Aluminum is known for its excellent thermal conductivity, making it an ideal material for heat sinks. Effective heat dissipation prevents overheating of the amplifier and ensures stable performance even at high volumes. This contributes to the longevity of the device and maintains sound quality during operation.

Wie kann die Eingangsempfindlichkeit des A4120 angepasst werden?

The Axton A4120 allows for adjustment of the input sensitivity in the range of 0.5 to 6 V. This variable setting enables the amplifier to be optimally matched to the signal strength of the audio source. A correct setting of the input sensitivity is crucial to avoid distortion and to ensure maximum sound fidelity and efficiency of the amplifier. Users can thus individually adjust the amplifier to their audio source to achieve the best sound experience.

Mit welchen Lautsprechern ist der Axton A4120 kompatibel?

The Axton A4120 amplifier is compatible with speakers that have an impedance of 4 ohms. This is a common standard in the automotive industry, which facilitates the integration of the amplifier into existing systems. While specific vehicle models are not mentioned in the description, the compact dimensions and performance of the amplifier allow for universal application in most vehicles. Users can therefore utilize a variety of speaker models with this amplifier.
