Another practical feature is that the amplifier is stackable, allowing for a compact arrangement of multiple units without obstructing access to the connection terminals.
The ETON MA 4 has compact dimensions of 184 mm in length, 160 mm in width, and 51 mm in height. These small measurements make it particularly suitable for installation in vehicles with limited space. Despite its compact size, the amplifier offers high performance and user-friendliness. When installing, care should be taken to ensure that there is enough space for air circulation around the amplifier to ensure optimal heat distribution.
The compatibility of the ETON MA 4 with car brands primarily arises from its flexible installation options and compact dimensions of 184 x 160 x 51 mm. Although no specific car brands are mentioned, the customizable mounting options and connections are designed to enable seamless integration into a variety of vehicles. The variable input voltage and adjustable filters enhance the adaptability of the MA 4, allowing it to be combined with most standard and high-quality audio systems from various car brands.
The ETON MA 4 offers an impressive damping factor of over 165 at 4 ohms. A high damping factor is important for improving control over the speaker diaphragm, leading to clearer and more precise audio playback, especially at low frequencies. This technical specification is an indicator of the amplifier's quality and its ability to produce detailed sound by minimizing unwanted movements of the speaker diaphragm. Especially if you enjoy listening to music in high quality, this damping factor is a significant advantage.
The ETON MA 4 features a user-friendly Auto-Sense On function that can work with both SIG and DC. This function allows the amplifier to automatically turn on as soon as an input signal is detected, significantly enhancing user comfort and simplifying integration into existing audio systems. The Auto-Sense On function is particularly useful because it eliminates the need for manual activation of the amplifier, ensuring a seamless connection between the audio source and the amplifier.
