Frequently Asked Questions about ACM-4.300

How much power does the Audiocontrol ACM-4.300 Amplifier deliver at 2 Ohm?

The Audiocontrol ACM-4.300 Amplifier delivers an impressive power of 4 x 75 W at 2 Ohm. This output power allows for the efficient operation of even demanding speaker systems and clearly reproduces significant volume differences. The high power at low impedance provides excellent dynamics, especially at low frequencies, and ensures an overall balanced audio playback. Technically speaking, this is an ideal solution for use in comprehensive car audio configurations where greater power output is desired without compromising sound clarity and detail richness. Perfect for enthusiasts who want to experience impressive sound experiences in their vehicle.

What Crossover settings does the ACM-4.300 offer?

The ACM-4.300 Amplifier is equipped with a Linkwitz-Riley Crossover that offers a crossover frequency of 12 dB/octave. You can choose between 80 Hz and 120 Hz, providing flexibility in sound adjustment. In situations where you want to utilize the full frequency range, a bypass option is also available to circumvent the crossover. These settings are ideal for adapting the sound to different speaker sizes and types, allowing you to achieve a tailored audio experience in your vehicle. Whether you want to emphasize deeper bass or higher mids, these options provide the necessary adaptability.

What is the signal-to-noise ratio of the Audiocontrol ACM-4.300?

The signal-to-noise ratio of the Audiocontrol ACM-4.300 is 102 dBA, referenced at 50 W @ 4 Ohm. This means that the amplifier produces very low background noise, even in quiet passages of your favorite music. A high signal-to-noise ratio is particularly important in vehicles, where a certain level of ambient noise is often present, as it ensures that the amplifier does not contribute unwanted background noise. A solid signal-to-noise ratio is crucial for clean sound quality and maintaining detail fidelity in any genre of music you listen to. Thus, the ACM-4.300 offers optimal audio playback with excellent clarity.

What are the dimensions of the ACM-4.300 and how do they affect installation?

The ACM-4.300 Amplifier measures a compact 23.8 x 7.6 x 4.4 cm and weighs 0.98 kg. These dimensions make it ideal for the modern car audio enthusiast who values a discreet installation. Due to its small size, the amplifier can be accommodated even in cars with limited space, such as under a seat or hidden in the trunk. Especially in more complex installations, where there is little room for additional devices, the ACM-4.300 stands out with its versatile mounting solutions. This allows for discreet integration without compromising audio performance.

What input options does the Audiocontrol ACM-4.300 offer?

The Audiocontrol ACM-4.300 offers versatile input options, including four balanced preamp inputs with a voltage range of 500 mV to 6 Vrms. This allows for the connection of a wide variety of signal sources, from simple head units to high-end processors. Additionally, there are four speaker level inputs that can handle input voltages from 3 V to 40 Vrms. This is particularly useful for integration into OEM systems, where replacing head units is often not possible or desired. These flexible connection options make the ACM-4.300 the ideal choice for upgrades in existing audio systems.

How does the GTOTM Signal Sense affect the functionality of the ACM-4.300?

GTOTM Signal Sense is an intelligent feature of the ACM-4.300 Amplifier that automatically turns on the amplifier as soon as an audio signal is detected. This is particularly advantageous as it eliminates the need for an additional turn-on wire and simplifies the installation process. For example, when you start your vehicle, the amplifier immediately recognizes the turn-on signal and begins operation. This feature ensures that the amplifier operates efficiently, saves power, and does not unnecessarily burden the battery's lifespan. The GTOTM technology is therefore a significant feature for anyone looking for a user-friendly solution.

What advantages do the active speaker level inputs of the ACM-4.300 offer?

The active speaker level inputs of the ACM-4.300 offer special advantages when integrating into existing OEM audio systems. By being able to directly process high speaker signals, the installation is significantly simplified. You do not need an additional adapter to connect the amplifier. A voltage range of 3 V to 40 Vrms ensures that all OEM audio system variations are covered. This feature of the ACM-4.300 is particularly useful when the existing unit is not to be replaced, but an amplification is necessary to enhance sound quality without being forced to replace components.

What warranty conditions apply to the ACM-4.300?

The ACM-4.300 Amplifier offers an indestructible Warranty of up to 5 years, provided the installation is carried out by an authorized AudioControl dealer. This generous warranty period speaks to the quality and reliability of the product and gives you as a user the assurance that any defects or malfunctions will be professionally addressed. Especially in a market flooded with options, such warranties are not a given and serve as an indicator of the manufacturer's confidence in their product quality. So make sure that the amplifier is installed by an authorized dealer to fully enjoy this long-term security.

What mounting options does the Audiocontrol ACM-4.300 Amplifier offer?

The Audiocontrol ACM-4.300 offers greater flexibility in mounting due to its reversible cover plate, allowing the amplifier to be installed in various positions. Its small dimensions of 23.8 x 7.6 x 4.4 cm facilitate installation even in tight or limited spaces, without compromising access to the various inputs and connections. The adaptability in placement allows you to hide the amplifier deep in the car or integrate it visibly as part of your audio system, depending on the spatial conditions and personal preferences.

How does the PFM subsonic filter affect audio performance?

The PFM subsonic filter of the ACM-4.300 operates at 32 Hz and effectively eliminates unwanted subsonic frequencies that could otherwise damage speakers. A PFM filter is particularly useful for minimizing excursions at low frequencies that are often imperceptible to listeners but potentially harmful. By filtering out these frequencies, the strain on the speakers is reduced, which not only increases their lifespan but also improves overall sound precision and clarity. Especially if you enjoy listening to music at high volumes, this filter can prevent the overall sound quality from suffering.
