Frequently Asked Questions about AD850


How much power does the Audio System Italy AD850 Amplifier provide?

The Audio System Italy AD850 Amplifier is a 1-channel Class D power amplifier that offers an RMS output power of 500 W at 4 Ohm and 850 W at 2 Ohm. This amplifier is ideal for users seeking strong and stable performance. The Class D amplifier ensures high efficiency and low heat loss, leading to excellent energy utilization – particularly relevant for compact installations with limited space. The technical features allow for impressive audio playback, suitable for various applications. Especially if you enjoy listening to music loudly, you will benefit from its power.

What adjustment options does the LOW PASS of the AD850 offer?

The AD850 from Audio System Italy offers a LOW PASS range of 30 Hz to 150 Hz with a 24 dB slope. This allows you to precisely adjust the audio frequencies to your sound preferences or speaker characteristics. Particularly in the lower frequency spectrum, this range optimizes the playback of subwoofers to ensure clear and powerful bass. A larger adjustment range enables fine-tuning of the sound profile by effectively filtering out unwanted frequencies. This setting is especially useful for optimizing bass quality across various music genres, from hip-hop to classical.

How does the BASS BOOST of the AD850 Amplifier work?

The BASS BOOST of the AD850 Amplifier provides a gain between 0 and +12 dB in the frequency range of 40 Hz to 160 Hz. This allows you to precisely increase the bass intensity of your audio signal and finely tune it to your listening needs. Especially if you plan to experience impressive depths with a certain "punch," you can vary this function to optimize it according to music style or personal preferences. The continuous adjustment provides flexibility and increased control over the sound experience.

How do I adjust the phase shift on the AD850?

The phase shift on the Audio System Italy AD850 Amplifier can be adjusted continuously from 0° to 180°. This gives you the opportunity to minimize phase issues that can arise from different placements of the Subwoofer in your car. By adjusting the phase shift, you synchronize the sound waves from the Subwoofer and main speakers, leading to a more homogeneous sound reproduction. A precise phase setting is crucial to ensure optimal bass pressure and clear sound layering across various vehicle scenarios and music genres.

What functions does the HighLevel input with Auto-Turn On offer?

The HighLevel input of the AD850 Amplifier is ideal for connecting to existing factory radio systems that do not have a dedicated preamp output. Thanks to the Auto-Turn On feature, the amplifier automatically turns on as soon as an audio signal is detected, simplifying installations and minimizing additional effort. This function is particularly useful in situations where space is limited or comprehensive modifications to the wiring are not possible. This ensures that music playback can begin seamlessly and without delay.

What are the dimensions of the AD850 Amplifier from Audio System Italy?

The dimensions of the AD850, measuring 300 x 148 x 52 mm, give it a compact profile that allows for installation even in limited spaces. Due to its low height and width, this amplifier is excellent for cars with restricted space without affecting functionality. Installation in hard-to-reach places, such as under car seats or in smaller trunk compartments, is straightforward with these dimensions. This provides the amplifier with placement flexibility while ensuring optimal heat dissipation and performance.

What is the Sub Remote control used for with the AD850?

The Sub Remote control included with the AD850 allows you to conveniently adjust the volume of the Subwoofer from a distance. This enables you to vary the bass intensity directly while driving, depending on your music style or listening preferences. This control is particularly helpful when listening to different music genres or when you want to adjust settings between personal and communal drives. This allows for a flexible and comfortable sound experience without needing to make adjustments directly on the amplifier.

What advantages does a Class-D Amplifier like the AD850 offer?

A Class-D Amplifier like the AD850 is characterized by high efficiency and low heat generation. This technology converts electrical energy into acoustic energy with minimal losses, resulting in improved efficiency. This also means that you need less cooling at full power, which is particularly beneficial in compact installations. Thanks to this efficiency, the dimensions of the amplifier are also smaller, without compromising on performance. Especially when you want to install a powerful yet energy-efficient audio system, the Class-D is an excellent choice.

How does the continuous phase adjustment work on the AD850?

The phase adjustment on the AD850 is continuously adjustable over a range of 0 to 180 degrees. With this feature, you can align the phase position of the speakers relative to each other to achieve coherent audio playback. This function is particularly relevant for eliminating phase issues that can arise from structural conditions in the vehicle, such as different distances between the speakers. This precise adjustment prevents certain frequencies from canceling each other out, significantly improving the overall expression of the music. Especially when listening to music with deep bass frequencies, you will feel the effectiveness of this adjustment.

What installation advantages does the AD850 amplifier offer due to its dimensions?

Thanks to its compact dimensions of 300 x 148 x 52 mm, the AD850 amplifier can be easily installed in various types of vehicles, even when space is limited. This compact design allows for flexible installations in vehicles of any size without compromising sound quality or power availability. However, care must be taken during installation to ensure there is enough space for adequate ventilation to avoid thermal overload. Especially in tight spaces within the vehicle, the AD850 offers optimal conditions for seamless integration into your audio system due to its dimensions.
