The 400.2 EVOX2 shows differentiated current draw depending on the operating scenario. In music operation, it draws 21 A, while it can consume up to 42 A with a resistive load. This information is essential for the correct planning of the audio system and the power supply in the vehicle. For interference-free and powerful audio playback, it is necessary that the vehicle's electrical system can deliver these currents without any issues. Therefore, the power source, such as the alternator or battery, should be adequately sized to meet the amplifier's demand.
The signal-to-noise ratio (SNR) of the 400.2 EVOX2 is 101 dB, which stands for high sound clarity and minimal distortion. A higher SNR value ensures that the input sound is reproduced unaltered and without disturbing noises. This is particularly noticeable in quiet music passages or at low volume settings, as the amplifier effectively minimizes distracting background noise. This is especially important for audiophiles who strive for the most original and authentic music reproduction and want to experience every nuance of the music.
For the correct installation of the 400.2 EVOX2, a power cable with a cross-section of 4 mm² is recommended to ensure that it can meet the power requirements of the amplifier. Regarding the audio outputs, cables with a cross-section of 2 x 2 mm² are optimal to ensure interference-free signal transmission and sound quality. It is important to adhere to the recommended cable specifications to avoid potential power losses or thermal issues. Well-sized cables contribute to optimizing the entire audio system and ensure reliable and efficient signal transmission.
To ensure the safe operation of the 400.2 EVOX2, a 25 A fuse must be installed as a protective measure. An important factor in using the amplifier is also the recommended minimum specification of a 40 Ah battery to balance the energy demand. These precautions not only protect the amplifier but also the entire electrical system of the vehicle from overload and potential damage. Adhering to these requirements is crucial for the safe and optimal use of the amplifier, especially at high volume or with complex audio systems.
