Frequently Asked Questions about DEFINIO 4

What power does the Xcelsus DEFINIO 4 provide at 4 Ohms?

The Xcelsus DEFINIO 4 delivers an impressive power of 105 Watts RMS per channel at 4 Ohms. This allows for clear and powerful audio playback for demanding music genres. However, if you operate your speakers in bridge mode, the power increases to 320 Watts RMS at 4 Ohms. This power selection offers the necessary flexibility to drive various speaker systems and ensures that your sound stands out optimally in any situation. For music lovers seeking extraordinary sound quality, this is ideal.

What is the frequency response of the Xcelsus DEFINIO 4?

The frequency response of the Xcelsus DEFINIO 4 ranges from 10 Hz to 40 kHz, allowing for a very wide range of acoustic details. This specification ensures that both deep bass and high frequencies are reproduced clearly and precisely. When installed in your vehicle or home audio system, you can expect the amplifier to be optimally suited for both classical and modern music styles. This frequency range provides the flexibility to represent both strong bass lines and clear highs, resulting in an exceptional listening experience.

What is the signal-to-noise ratio of the Xcelsus DEFINIO 4?

The signal-to-noise ratio (SNR) of the Xcelsus DEFINIO 4 is an impressive 90 dB A-weighted. A higher signal-to-noise ratio indicates that the amplifier is capable of producing a pure output signal with minimal background noise. This is particularly important for hi-fi enthusiasts who want to enjoy every subtle sound aspect of their music. Such a level of performance ensures that audio signals are reproduced not only powerfully but also exceptionally clearly, contributing to an excellent sound experience, especially in demanding acoustic environments.

What are the dimensions of the Xcelsus DEFINIO 4 and how does that affect installation?

The Xcelsus DEFINIO 4 measures 418 x 104 x 270 mm, making it compact yet powerful. The installation of this Amplifier can be done in various vehicle models under the seat or in the trunk, as long as the space supports these dimensions. Ensure there is enough room for air circulation to avoid overheating. This compact design also allows for easy integration into existing audio systems, enabling the DEFINIO 4 to deliver its outstanding performance discreetly.

What amplifier class does the Xcelsus DEFINIO 4 use?

The Xcelsus DEFINIO 4 is a Full Range Digital Amplifier. This means it efficiently converts digital signals into audio outputs by combining high energy efficiency with minimal heat output. Full Range Digital Amplifiers are known for their ability to reproduce the entire frequency spectrum clearly and powerfully, which is especially beneficial for multiple speaker types. This class of amplifier is significantly more efficient than analog devices, ensuring a longer lifespan and lower energy consumption in daily use.

What filter functions does the Xcelsus DEFINIO 4 offer?

The Xcelsus DEFINIO 4 features adjustable high-pass and low-pass filters in the range of 50 Hz to 500 Hz. These filters allow you to optimize the frequency ranges transmitted to your speakers. For example, you can filter out lower bass frequencies from the high-frequency speakers or suppress high-frequency sounds from subwoofers to enhance the efficiency and sound clarity of your system. This flexibility ensures that the amplifier can be optimally adjusted to different speaker and music genre characteristics.

What input sensitivity does the Xcelsus DEFINIO 4 offer?

The input sensitivity of the Xcelsus DEFINIO 4 ranges from 0.2 to 6 V. This range allows the amplifier to work with different sources and signal strengths, whether from a conventional radio or a high-performance DAC. By adjusting your input signals within these ranges, you can ensure that the amplifier delivers the best possible sound quality. Thus, it can be flexibly used in various audio systems to optimally amplify both quiet and loud sources, providing a consistent listening experience.

What is the damping factor of the Xcelsus DEFINIO 4?

The damping factor of the Xcelsus DEFINIO 4 is more than 100. It defines the control that the Amplifier exerts over the speaker diaphragm to minimize resonances. A higher damping factor means more precise control, especially at low frequencies. This is crucial for reproducing bass clearly and without distortion. Audiophiles particularly appreciate such a damping factor, as it ensures clean, uncolored playback even with complex musical pieces, without compromising clarity or detail.

What is the power consumption of the Xcelsus DEFINIO 4 at idle and under load?

At idle, the power consumption of the Xcelsus DEFINIO 4 is only 0.7 A, which corresponds to 0.35 A per channel. Under maximum load, the consumption is 60 A. This efficiency ensures that the Amplifier has minimal energy consumption at rest, which is particularly advantageous in vehicles with low-capacity alternators. Under full load, the Amplifier can still produce immense output power, making it ideal for power-intensive applications in cars or home theater systems. This balance between efficiency and performance is another reason for its popularity.

How does the THD value affect the audio quality of the Xcelsus DEFINIO 4?

The Total Harmonic Distortion (THD) of the Xcelsus DEFINIO 4 is below 0.02% at 5 W and 1 kHz. This low value means that the distortions introduced by the Amplifier are extremely low, resulting in clean and uncolored playback. Especially at high volumes and with complex musical styles, this ensures that no unwanted harmonic distortions occur. Audiophile listeners and tech enthusiasts who value an authentic sound image will benefit from this outstanding technical feature of the DEFINIO 4.
