High-end audio performance with full-Mosfet technology of the audio system amplifier

The full MOSFET technology of the HX-85.4 audio system stands for superior sound quality. This technology enables faster and more efficient signal processing, reducing distortion to a minimum. Compared to conventional amplifiers, this technology enables the HX-85.4 to offer better signal-to-noise ratios and thus clearer audio output. This is especially important at low frequencies, where precision and clarity are crucial. Increasing or decreasing the MOSFET power would result in fluctuations in audio quality, which would limit the high-end design.

Burr-Brown preamplifier for superior signal quality and sound fidelity

The Burr-Brown preamplifier in the HX-85.4 is a highlight among audio components. Engineered for the utmost precision, it ensures minimal signal distortion and authentic sound reproduction. Burr-Brown is known for its high-quality processing techniques, ensuring even the finest sound details are audible. Comparable amplifiers without this preamplifier tend to lose these subtle details, compromising sound fidelity. The precise signal processing reproduces your music as intended—vivid and authentic.

Variable and stepless phase shift from 0-360° for individual sound adjustment

The ability to continuously adjust the phase shift between 0 and 360° is one of the key features of the HX-85.4 amplifier. This function is crucial for optimally adapting the audio reproduction in the vehicle to the speaker position. Fine-tuning the phase allows phase shifts to be corrected and the spatiality of the sound to be enhanced. Other amplifiers with a fixed phase value do not offer this adjustment option, which can lead to compromises in the richness of the sound. Fine-tuning allows the acoustician to create the perfect sound environment.

Efficient MWPC security system protects and optimizes performance

The Audio System amplifier is equipped with an efficient safety system, the MWPC. This system continuously monitors operating temperatures and the power supply to prevent the risk of overheating or short circuits. If the temperature or voltage reaches critical levels, the MWPC automatically reacts and reduces the power or shuts down to prevent damage. A more sophisticated safety system could lead to unnecessary performance reductions, while a simpler system may not provide sufficient protection.

Dimensions and elegant design of the Audio System HX-85.4

The Audio System HX-85.4 measures 416 x 240 x 53 mm, a dimension suitable for most vehicle installations. Its slim and elegant design allows the amplifier to integrate seamlessly into various vehicle interiors without attracting attention or creating space constraints. Its size compared to other amplifiers allows for discreet installation, while its aesthetics meet the requirements of a sophisticated design. A larger amplifier could complicate installation in the vehicle, while a smaller one might not provide the same cooling performance.

Advantages of temperature-dependent fan cooling for optimal operation

The HX-85.4's continuously variable, temperature-dependent fan cooling ensures that the amplifier doesn't overheat, even during intensive use. Sensors constantly monitor the temperature, and the cooling automatically adjusts to meet demand to ensure an optimal operating temperature. This maximizes the amplifier's lifespan and performance. Other amplifiers without this feature run the risk of overheating due to a lower cooling effect, which could lead to premature performance degradation.

Extremely flexible input sensitivity from 0.2-8 V for universal connectivity

The HX-85.4's 0.2-8 V input sensitivity allows it to be connected to virtually any preamplifier or audio system, regardless of its current rating. This flexibility allows the amplifier to be paired with a wide variety of audio sources without signal loss. Systems with a narrower range would offer less compatibility, which could lead to suboptimal performance at different input levels. The wide range therefore ensures first-class adaptability.
