Frequently Asked Questions about A401

How much power does the Axton A401 Amplifier provide?

The Axton A401 Amplifier delivers impressive output power that meets the highest demands. At an impedance of 4 Ohm, the power is 4 x 100 W, while at 2 Ohm, it can provide up to 4 x 170 W. Additionally, in bridged mode at 4 Ohm, a power of 2 x 350 W can be achieved. These power parameters allow the A401 to perform excellently in both conventional and more demanding audio systems that require higher pulse stability. The high performance enables efficient operation of various speaker configurations.

What frequencies can the Axton A401 Amplifier process?

The Axton A401 is designed to handle a wide range of frequencies. Its frequency response ranges from 10 Hz to 35 kHz, covering both deep bass and high frequencies. This allows for detailed audio playback. Additionally, the amplifier is equipped with integrated electronic crossovers that offer a variable high-pass and low-pass filter of 12 dB/octave, adjustable in the range between 40 Hz and 400 Hz, allowing the sound to be tailored to specific listening preferences.

Is the Axton A401 Amplifier compact enough for my vehicle?

Yes, the Axton A401 Amplifier is very well suited for installation in vehicles with limited space, thanks to its ultra-compact dimensions of 230 x 40 x 105 mm. Especially in vehicles with restricted installation space, the amplifier shows its strengths, as it can be easily installed even in tight conditions. Furthermore, the sleek design meets the requirements of modern vehicles that demand aesthetic and functional integrity. Despite its size, it offers high power reserves due to its Class-D construction.

How does the Axton A401 support modern vehicles with start/stop automation?

The Axton A401 Amplifier is fully compatible with vehicles equipped with a start/stop system. This capability ensures that the amplifier can be seamlessly integrated into a wide range of modern automobiles without interruptions in audio performance. Even during the frequent on and off cycles of the start/stop function, operation remains stable, which is particularly advantageous in urban traffic. The amplifier maintains audio quality and Lisa standards while the engine is turned on or off.

What types of inputs does the Axton A401 support?

The Axton A401 is equipped with both high-level and low-level inputs, providing high flexibility in connecting to various audio sources. This means that the amplifier can be connected directly to common car radios as well as modern multimedia devices. The variable input sensitivity of 0.4 – 10 V allows for optimal adjustment of the amplifier to diverse signal sources. Thanks to the auto turn-on function, which activates via DC offset or through the music signal, the amplifier is automatically turned on as soon as a signal is detected.

What cooling technology does the Axton A401 use and why is it important?

The Axton A401 Amplifier uses an aluminum heat sink that ensures optimal heat dissipation. This cooling technology is particularly important for the efficient operation of the amplifier, as it prevents overheating and protects the components from thermal damage. This not only ensures a long lifespan for the device but also maintains consistent performance even under intense use. Especially with the compact design of a Class-D amplifier, effective cooling technology is essential to meet high power demands.

What filtering options does the Axton A401 Amplifier offer?

The Axton A401 is equipped with integrated electronic crossovers that offer high-pass and low-pass filters of 12 dB/octave each. These filters can be varied in the frequency range of 40 Hz to 400 Hz, allowing users to make customized audio settings. This enables precise frequency separation and ensures that the amplifier can optimally drive various types of speakers. The filter systems are particularly advantageous for achieving the best possible sound performance in different acoustic environments.

How is the Axton A401 installed in the car?

The installation of the Axton A401 in the vehicle is relatively straightforward due to its compact design. With dimensions of 230 x 40 x 105 mm, the amplifier can be integrated into smaller vehicle interiors. It is particularly important to consider the placement to utilize the aluminum heat sink more effectively. The connection is made via the high-level and low-level inputs, with the auto turn-on function simplifying integration into the existing system. This ensures that the amplifier is ready for use as soon as an audio signal is detected.

What is the signal-to-noise ratio of the Axton A401?

The Axton A401 amplifier offers a signal-to-noise ratio of 85 dB, which means that the amplifier is capable of delivering a clear and noise-free audio signal. Such a signal-to-noise ratio is crucial for sound quality, as it ensures that background noise is minimized and music is reproduced clearly and in detail. This feature is particularly evident when reproducing fine audio textures and quiet background sounds, making the A401 the ideal amplifier for audiophile demands.

What advantages does the Class-D design of the Axton A401 offer?

The Class-D design of the Axton A401 amplifier offers significant advantages in terms of efficiency and heat dissipation. Such amplifiers are known for their high energy efficiency, meaning they consume less power while delivering high performance. This technology reduces energy loss in the form of heat, allowing for a compact design without loss of power. For vehicles with limited space or high energy efficiency requirements, Class-D technology is ideal for still achieving powerful sound.
