Frequently Asked Questions about ABR-500.4

What is the power output of the Amplifier ABR-500.4 at different impedances?

The Amplifier ABR-500.4 delivers an RMS power of 120 W per channel at 2 Ohms, while it operates at 90 W per channel at 4 Ohms. If you want to bridge the channels, the Amplifier outputs 250 W per channel at 4 Ohms. The Amplifier is designed to support a minimum load of 2 Ohms per channel or 4 Ohms in bridged mode. These power values allow you flexible adjustment, depending on the specific requirements of your speakers and their impedance.

Does the ABR-500.4 support a variable Crossover?

Yes, the ABR-500.4 is equipped with a variable Crossover that offers a slope of 12 dB/octave. This allows you to precisely adjust the frequency separation between the Subwoofer and full-range speakers. The low-pass filter is adjustable between 50 and 300 Hz, while the high-pass filter covers a range of 50 to 12000 Hz. This way, you can set and optimize individual sound profiles according to your preferences, which is particularly beneficial for complex audio systems in cars.

How do the bass settings work on the ABR-500.4?

The Amplifier ABR-500.4 gives you the option to adjust the bass level in three stages: 0, +6, and +12 dB. This setting allows you to specifically enhance the bass range, depending on your music genre or personal preferences. You can make the bass more powerful, which is especially useful for music genres with a strong low-frequency range. In extensive sound systems, it is crucial to clearly represent every musical element, and this adaptability maximizes the audio performance.

What frequency range does the model ABR-500.4 cover?

The Amplifier ABR-500.4 operates in a frequency range of 10 to 20000 Hz. This wideband frequency response ensures that all relevant audio frequencies can be well represented, from deep bass frequencies to high sound components, allowing for clear and detailed playback. This comprehensive coverage enables the combination of both Subwoofer and mid to high frequencies in high quality, ensuring a complete, dynamic audio output. Perfect for maximizing the full potential of your speakers.

What power supply does the ABR-500.4 require?

The Amplifier ABR-500.4 requires an operating voltage between 9 and 15 volts. This flexibility in power supply ensures that the amplifier can be operated without issues in most vehicles, even if the onboard voltage varies due to electrical load fluctuations. This is particularly advantageous in older vehicles or with additional electrical consumers, as stability during operation is guaranteed. The amplifier remains within its optimal operating range to ensure maximum efficiency and sound quality.

What is the signal-to-noise ratio of the ABR-500.4 and why is it important?

The signal-to-noise ratio (SNR) of the ABR-500.4 is ≥ 90 dB. This ratio indicates how much stronger the useful signal is compared to interference or background noise. A higher SNR means clearer sound reproduction without disturbing noises. For detail-oriented listeners, a high dynamic range is important to retain subtleties even in louder passages. This technical feature of the amplifier is crucial to ensure the originality and precision of the music without unwanted disturbances.

How do I install the ABR-500.4 in my vehicle?

When installing the ABR-500.4, you should ensure that there is enough space for the dimensions of 31.2 x 18.2 x 5.3 cm in the vehicle. Use appropriate input terminals with 6 Ga and output terminals with 10 Ga to ensure a secure connection. Proper wiring contributes to optimal performance. Make sure to mount the amplifier in an isolated location to avoid interference from vibrations or external influences. Details on compatibility with car models are important in case additional modifications may be needed.

What input signals can the Amplifier ABR-500.4 process?

The Amplifier ABR-500.4 is designed for input signals from 0.2 to 6 V. This adaptability allows the amplifier to cleanly process a wide range of audio sources, from quiet to powerful output signals. It can optimally support both simple and more complex audio settings. This flexibility ensures that you always receive stable and clear sound quality, regardless of your audio source, while also ensuring smooth operation to promote peak performance of your audio systems.

Why is the Class AB of the Amplifier ABR-500.4 advantageous?

The ABR-500.4 is a Class AB amplifier that combines the benefits of Class A and Class B. This means you get a balanced mix of high sound quality and energy efficiency. While Class A is known for outstanding sound fidelity, Class B offers improved efficiency. The AB amplifier thus guarantees clear and powerful sound with low heat generation and higher energy utilization. Perfect for everyday use in vehicles, where both quality and efficiency are required.

How does the minimum load affect the use of the ABR-500.4?

The minimum load of the ABR-500.4 is set to 2 ohms per channel and 4 ohms in bridged mode, which is flexible for various speaker configurations. This specification is important to avoid overloads and to use the amplifier within its safe operating range. Particularly relevant when integrating custom car Hi-Fi solutions, as this allows the amplifier to operate efficiently and deliver optimal audio quality without being overstrained, minimizing the risks of damage or sound loss.

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
