The 400.4 EVOX2 from Soundigital delivers an impressive power of 4 x 100 watts RMS at an impedance of 2 ohms. This enables powerful sound reproduction, ideal for demanding audio systems. Due to the high efficiency, the speakers are operated efficiently, maintaining sound quality even at high volumes. Especially if you enjoy listening to music loudly or prefer high volume levels, this power guarantees outstanding sound quality without distortion. Additionally, the RTGP system ensures efficient thermal management and increases power stability even during longer listening sessions.
The dynamic heat recovery (DTR) of the 400.4 EVOX2 accelerates the heat exchange between the electronic components and the heat sink. This is achieved through an innovative technology that optimizes heat dissipation to the environment while simultaneously increasing overall efficiency. As a result, not only is the lifespan of the amplifier extended, but its efficiency is also improved, allowing for longer operating times with consistent performance. This is particularly advantageous during intense audio playback, as it reduces distortion and maintains sound quality.
The frequency response of the Soundigital 400.4 EVOX2 ranges from 5 Hz to 22 kHz (-3dB). The low-pass filter has a range of 45 Hz to 850 Hz at 12 dB/octave, while the high-pass filter also operates from 45 Hz to 850 Hz at the same slope. This extensive frequency coverage allows for precise sound tuning, enabling both deep bass and high frequencies to be reproduced clearly and in detail. Especially if you value a balanced sound image, you can use this adjustment option to tailor the sound output specifically to your preferences.
With a compact design, the 400.4 EVOX2 offers efficient energy management and impressive sound quality. The dimensions of 12.3 x 11.3 x 5.0 cm make integration flexible and ideal for limited spaces. The efficiency is 83%, demonstrating how effectively it converts energy into sound. The power consumption peaks at 19A for music and a maximum of 35A. These technical features enable stable performance with minimal energy loss, which not only maintains high sound quality but also reduces operating costs and ensures the longevity of the components.
The 400.4 EVOX2 offers two adjustable ranges for input sensitivity. For the RCA input, it ranges from 0.18 V to 2.09 V, while the high-level input allows a sensitivity of 1.2 V to 15.13 V. These flexible settings ensure that the amplifier can efficiently integrate a wide variety of source devices without loss of adjustment. Even with audio sources that have lower output levels, the sound performance is optimally realized. Especially in a setup with varying input signals, this versatility is crucial for achieving a consistently clear and powerful sound without disturbing influences.
The compact amplifier Soundigital 400.4 EVOX2, with dimensions of 12.3 x 11.3 x 5.0 cm, is ideal for installation in tight spaces. The placement can vary depending on the vehicle model, but typically installation is possible under the seat, in the trunk, or behind the dashboard. Good ventilation is important to ensure thermal efficiency. Power supply is provided via a power cable of 8mm², and for the audio outputs, 2 x 1.5 mm² audio cables are recommended. A minimum battery value of 20Ah supports reliable power supply.
The vibration damping of the 400.4 EVOX2 is crucial for performance in demanding environments. The special device integrated into the amplifier acts like springs, reducing the impact of vibrations on the electronic circuit board. This increases lifespan and reliability by counteracting the structural stresses that can arise from driving movements or external vibrations. For car audio applications, this protective mechanism is particularly valuable as it protects the electronics during operation and maintains sound quality consistently over longer periods.
The 400.4 EVOX2 from Soundigital has been optimized for exceptional stability during long operating times. The exclusive RTGP system (Thermal Recovery for Power Generation) plays a key role by providing excellent thermal efficiency that prevents overheating and extends the lifespan of the components. The dynamic heat dissipation allows for accelerated heat exchange, which increases the amplifier's efficiency and leads to lower distortion during prolonged use. Thus, the amplifier is ideally suited for demanding applications where continuous operation is expected.
The signal-to-noise ratio (SNR) of the 400.4 EVOX2 is 96 dB. This high value indicates how well the amplifier can separate the audio signal from the noise. A higher SNR means that the ratio between the useful signal and background noise is improved, which is particularly important for clear and uncolored sound reproduction. In high-quality audio equipment, a high SNR is crucial for reproducing the fine details in music and delivering audio quality that is free from disturbing noise even in quiet passages.
The damping factor of the 400.4 EVOX2 is 200, which allows for tight control over the speaker membranes. A high damping factor improves the transient response of the speakers, minimizes unwanted resonances, and ensures precise bass reproduction. This characteristic is particularly advantageous in musical pieces with low frequencies, as it enhances dynamics and detail fidelity. With a high damping factor, not only is acoustic precision maximized, but the amplifier's power reserves are also optimally utilized, resulting in overall superior sound quality.
