Frequently Asked Questions about ABR-700.4

What RMS power does the Amplifier provide at 2 Ohms?

The ABR-700.4 Amplifier delivers an RMS power of 175 W per channel at a load of 2 Ohms. This ensures significant performance and allows you to work with four-channel stereo systems at a high output power of a total of 700 W. Notably, the power is measured at a voltage of 14.4 V, which is common when used in vehicles. It is crucial that the minimum load per channel is 2 Ohms, ensuring high efficiency and compatibility with low-impedance speakers, ideal for complex car audio setups.

How does the bass adjustment level work on the ABR-700.4 model?

This model offers an adjustable bass adjustment level that can be set in three stages: 0 dB, +6 dB, and +12 dB. This feature is particularly interesting for music lovers who want to customize their audio experience. Keep in mind that an increase of +12 dB already means a significant boost in the bass component, which is especially beneficial for bass-intensive music genres like EDM or Hip-Hop. With the variable settings, you can perfectly tune the sound reproduction to your preferences and the acoustics of your vehicle without compromising sound quality or clarity.

What are the dimensions of the ABR-700.4 Amplifier?

The Amplifier measures 41.5 cm in length, 18.2 cm in width, and 5.3 cm in height. These compact dimensions make it relatively easy to install the device in various vehicle models without taking up too much space. Planning the placement is crucial for effective installation to ensure optimal ventilation and cooling and to avoid power losses. Ideally, the installation should be done in a location where air circulation is not restricted to prevent possible overheating due to high power output.

What frequency range does the high-pass filter cover?

The ABR-700.4 features a high-pass filter that covers frequencies from 50 Hz to 12000 Hz. This bandwidth is particularly useful for eliminating unwanted low tones that often cause distortion in speakers with limited bass performance. The high-pass filter ensures clean high-frequency reproduction by selectively filtering out low frequencies. This filter is excellent for integration into audio setups that require a clearly defined sound and improved balance in frequency distribution, ideal for discerning music and audio enthusiasts.

What should I consider when installing the Amplifier in the car?

When installing the ABR-700.4, you should ensure that the vehicle's operating voltage is in the range of 9 - 15 V, which matches the operating voltage of the Amplifier. It is also important to use appropriate input terminals with 4 Ga and output terminals with 10 Ga to ensure a secure and loss-free connection. Furthermore, it is essential to consider the minimum load of 2 Ohms per channel and 4 Ohms in bridge configuration to avoid overloads and damage to the speakers or the Amplifier unit.

What frequency ranges does the low-pass filter of the ABR-700.4 cover?

The low-pass filter of the ABR-700.4 covers a range from 50 Hz to 300 Hz. This is particularly useful for use in Subwoofer systems, where it is important to eliminate high frequencies that could disrupt a clear bass sound. The filter ensures precise and defined bass reproduction by removing unwanted high frequencies from the bass range. This achieves seamless integration between the Subwoofer and other speakers, resulting in a balanced and harmonious sound image. A must for audio enthusiasts.

What class characteristic does the ABR-700.4 Amplifier have?

The ABR-700.4 is a Class AB Amplifier, which distinguishes it for a combination of energy efficiency and sound quality. This amplifier class is known for its balanced approach, as it combines the low power consumption of Class A amplifiers with the high output power of Class B amplifiers. Choosing a Class AB Amplifier means you benefit from clear and even sound reproduction while minimizing heat generation and energy losses. This is crucial for long, trouble-free listening enjoyment.

How does the operating voltage range affect the performance of the Amplifier?

The operating voltage range of the ABR-700.4 is between 9 and 15 V. A stable supply voltage within this range ensures that the Amplifier operates under optimal conditions and can deliver its maximum power of 700 W. One of the most critical aspects is avoiding voltage drops that could impair audio quality. Therefore, checking your vehicle's electrical systems is important to ensure they meet the requirements. A properly adjusted voltage system prevents unwanted shutdowns or power losses.

How good is the signal-to-noise ratio (SNR) of the ABR-700.4?

With a signal-to-noise ratio of ≥ 90 dB, the ABR-700.4 Amplifier is positioned within a very acceptable range for high-fidelity audio devices. This ratio indicates how much stronger the useful signal is compared to the background noise. A higher SNR means you can enjoy a cleaner, distortion-free audio experience. This is especially crucial when reproducing fine sound details, allowing you to experience music without unwanted background noise. The Amplifier maintains sound purity even at high levels.

What voltage peaks can the input of the Amplifier handle?

The ABR-700.4 can handle input voltage peaks between 0.2 V and 6 V. This wide flexibility is crucial for dealing with a variety of signal sources and input attenuations. This capability proves advantageous, especially when integrating into existing audio setups with variable output voltage from different head units and preamplifiers. This ability allows for optimal input matching to minimize distortion and ensure outstanding sound performance without level losses. This achieves exceptional sound quality and consistently good audio performance.

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.
