At a voltage of 14.4V, the power increases to 4 x 145 WRMS at 4Ω, 4 x 221 WRMS at 2Ω, and 4 x 335 WRMS at 1Ω. In bridged mode, the amplifier achieves 2 x 442 WRMS at 4Ω and 2 x 669 WRMS at 2Ω.

What innovative technology is used in the 1200.4 EVOX2 amplifier?

The 1200.4 EVOX2 from Soundigital utilizes the exclusive RTGP system for thermal coupling, which improves the amplifier in terms of thermal efficiency and robustness. Additionally, it features a dynamic heat dissipation system to enhance efficiency under continuous load. The DTR technology enables dynamic heat recovery by accelerating the heat exchange of the electronic components with the heat sink. This innovative technology contributes to increased performance and longevity by reducing the effects of vibrations on the circuit board and enhancing efficiency.

What is the current draw of the 1200.4 EVOX2 at maximum power?

At maximum power, the 1200.4 EVOX2 from Soundigital draws current in the range of 113 A. For normal music operation, a current draw of 57 A is recorded. The recommended fuse for music operation is 70 A to prevent thermal overload and thus ensure the reliability of the amplifier. These values reflect the efficient power consumption of the device, which scores with a total efficiency of 84% regarding power consumption, ensuring stable and reliable operation.

How efficiently does the Soundigital 1200.4 EVOX2 amplifier operate?

The Soundigital 1200.4 EVOX2 features an impressive overall efficiency of up to 84%, indicating that most of the energy consumed is effectively converted into power. This high efficiency contributes to stable operation and a reduction in distortion. In audio engineering, efficiency is of interest because it can directly impact sound quality and reliability. In the context of energy conversion, efficiency plays a crucial role in achieving high sound fidelity without unnecessary energy loss.

What frequency range does the 1200.4 EVOX2 amplifier operate in?

The frequency range of the 1200.4 EVOX2 amplifier extends from 5 Hz to 22 kHz at -3dB. This wide frequency range allows for detailed sound reproduction that captures all nuances of the music. With a signal-to-noise ratio (SNR) of 91 dB, the amplifier ensures that the sound is clear and free from disturbing background noise. Additionally, there are flexible crossovers with HPF and LPF from 45 Hz to 850 Hz. These allow for precise adjustment to personal music preferences or the specific requirements of the respective speaker.

What are the dimensions of the 1200.4 EVOX2 amplifier and how is the installation?

With a compact size of 18.1 x 13.6 x 5.5 cm, the 1200.4 EVOX2 amplifier from Soundigital can easily fit into tight spaces. For mounting, it is advisable to ensure adequate airflow to optimally utilize the thermal properties of the RTGP system. Due to its small size, the amplifier is ideal for vehicles with limited installation space. The installation can be easily done under seats or in small compartments without significant loss of storage space.

Is the 1200.4 EVOX2 reliable even with voltage fluctuations?

The Soundigital 1200.4 EVOX2 amplifier operates within a voltage range of 8V to 16V, ensuring reliable performance even with voltage fluctuations in automotive applications. Such voltage flexibility is particularly useful in vehicles whose electrical systems occasionally deviate from nominal voltage values. The developed systems for thermal coupling and dynamic heat dissipation significantly contribute to the amplifier remaining efficient at various voltage levels while maintaining its performance specifications.

What does the RTGP system mean in the Soundigital 1200.4 EVOX2?

RTGP stands for Thermal Recovery for Power Generation, an innovative system used in the 1200.4 EVOX2 by Soundigital to maximize thermal efficiency and ensure outstanding performance stability. This technology improves energy efficiency by specifically removing heat from the Amplifier, thus providing cooling. Especially during intense use or in adverse environmental conditions, RTGP offers higher operational reliability and extends the lifespan of the electronic components, which ultimately ensures powerful and reliable sound reproduction.

What role does damping play in the 1200.4 EVOX2?

The damping devices of the Soundigital 1200.4 EVOX2 reduce the impact of vibrations on the electronic circuit board. This technology functions similarly to springs that protect the device components. This damping results in fewer external vibrations affecting sound quality, which is particularly relevant in mobile environments like vehicles. This not only increases reliability but also extends the lifespan of the hardware, ensuring stable sound and minimized technical failures, regardless of environmental conditions.

How low is the distortion in the sound reproduction of the 1200.4 EVOX2?

The 1200.4 EVOX2 from Soundigital impresses with a THD+N (Total Harmonic Distortion plus Noise) value of 0.1% at 10% rated power. This low level of distortion ensures clean and authentic sound reproduction. Notably, it influences the precision of music output, maintaining top-level sound quality even at high amplifier power. This feature not only keeps the musical experience intact but also enhances it. Such technical sophistication is essential for audiophile users who demand the highest sound fidelity.
