    Frequently Asked Questions about ACX-300.4

    What power does the AudioControl ACX-300.4 Amplifier provide?

    The AudioControl ACX-300.4 Amplifier delivers an output power of 4 x 75 Watts at 2 Ohm and 4 x 50 Watts at 4 Ohm. In a bridged configuration, the power reaches an impressive 150 Watts at 4 Ohm, making it particularly versatile for various applications. Ideal for operation under different impedance conditions, this amplifier is capable of handling both high and low input levels. This flexibility is complemented by the integrated Linkwitz-Riley crossover, which offers crossover frequencies of 80 Hz and 120 Hz, as well as a bypass mode.

    Can the ACX-300.4 also be used in bad weather conditions?

    The AudioControl ACX-300.4 Amplifier is equipped with an IPX6 protection class, meaning it is protected against strong water jets. This feature makes it ideal for use in harsh environments such as on boats or motorcycles, where it may be exposed to water. Thanks to its robust design, sound quality remains unaffected even when the amplifier is exposed to extreme conditions. This weather resistance gives users the freedom to use their audio systems even in difficult weather conditions without concerns.

    How is the installation of the AudioControl ACX-300.4 carried out?

    The installation of the AudioControl ACX-300.4 Amplifier is easy and quick to implement thanks to the installation-friendly quick connection wiring. The dimensions of 22.8 x 9.8 x 5.7 cm allow the amplifier to be placed in various installation positions. It is important to use the correct safety fuses, with a fuse rating of 30A recommended. Ensure that the amplifier is adequately ventilated to avoid overheating. The compact design facilitates installation even in tight spaces, making the amplifier universally applicable in almost any setup.

    What features do the inputs on the ACX-300.4 offer?

    The ACX-300.4 from AudioControl is equipped with preamp/speaker level inputs that offer flexible connection options. Four inputs allow for high and low voltage modes with a low-level range of 500 mV to 6 Vrms and a high-level range of 1 Vrms to 12 Vrms. This allows the Amplifier to adapt to various source devices without compromising sound quality. With support for different input modes, you can optimally configure it to your specific needs.

    What frequency ranges does the ACX-300.4 Amplifier cover?

    The AudioControl ACX-300.4 Amplifier covers an extremely wide spectrum with a frequency response of 26 Hz to 22 kHz. This guarantees clear and powerful sound across the entire audible frequency range, ideal for audiophiles and music lovers. A signal-to-noise ratio of 106 dBA, referenced at 50 W at 4 Ohm, ensures clean and dynamic sound output. Additionally, the 12 dB/octave Linkwitz-Riley Crossover controls the crossover frequencies at 80 Hz and 120 Hz, enhancing tonal adaptability, while the bypass mode allows for unaltered signal transmission.

    What safety and protection features does the AudioControl Amplifier offer?

    The ACX-300.4 is not only robust in performance but also well protected against external influences thanks to its IPX6 certification. This protection class ensures that the Amplifier is resistant to water jets from all directions without compromising performance. In addition to physical protection, the Amplifier offers a low distortion rate of THD+N < 0.2%, ensuring clear sound. Especially in demanding environments, this Amplifier is a reliable component in any sound system due to its protective features.

    How does the Crossover in the ACX-300.4 work?

    The integrated Crossover in the AudioControl ACX-300.4 is of the Linkwitz-Riley type and offers a slope of 12 dB/octave. This allows for precise adjustment of the crossover frequencies at 80 Hz and 120 Hz to achieve optimal sound separation. The bypass mode also allows the unaltered audio signal to be routed directly from the input module to the output stages. This is particularly valuable when using external crossovers or when you need a completely unrestricted audio signal delivery.

    Which vehicle types is the ACX-300.4 compatible with?

    The AudioControl ACX-300.4 is suitable for installation in a variety of vehicle types, from cars to boats to motorcycles, thanks to its compact dimensions of 22.8 x 9.8 x 5.7 cm. This flexible fit allows the Amplifier to be used easily in both cars with limited space and larger vehicles. When integrating into existing audio systems, attention should be paid to the impedance and power settings to achieve optimal results. This versatility in installation makes the ACX-300.4 a preferred choice for sound enthusiasts.

    How does the AudioControl ACX-300.4 affect sound quality?

    The AudioControl ACX-300.4 Amplifier significantly improves sound quality through its high component precision and a noise ratio of 106 dBA, allowing even quiet sounds and fine nuances to be reproduced clearly. Especially if you enjoy listening to music loudly, the low distortion rate of less than 0.2% THD+N ensures that the sound remains clean even at high volumes. These features make the ACX-300.4 a powerful Amplifier, suitable for discerning listeners seeking a strong and detailed sound.
