Frequently Asked Questions about AS4120

What music genres can the AS4120 Amplifier optimally play?

The AS4120 from Audio System Italy is designed for versatile music playback. Thanks to its four separate channels, it is possible to play various music genres in high quality. The combination of Pre-In and Speaker-In inputs allows for adaptation to a wide range of headphone units and audio sources. With a frequency range coverage of 5 Hz to 25,000 Hz, the AS4120 offers excellent sound fidelity for both deep bass and high frequencies. Especially if you enjoy listening to music loudly, the bass boost from 0 to +12 dB at 45 Hz will ensure powerful low tones.

What power does the AS4120 deliver at different Ohm resistances?

The AS4120 Amplifier from Audio System Italy delivers various RMS powers at 14.4V depending on the Ohm resistance. At a resistance of 4 Ohm, the amplifier reaches 125 Watts RMS per channel, while at a 2 Ohm resistance, it delivers 160 Watts RMS per channel. For those who want to use the amplifier in bridged mode, 260 Watts RMS is available at 4 Ohm. These configurations allow for flexible adaptation to different speaker setups. So, if you use different speaker resistances, the AS4120 will always provide the appropriate power.

How is the AS4120 installed in a car without causing brand issues?

To optimally integrate the AS4120 Amplifier into a vehicle, the dimensions of 385 mm x 52 mm x 230 mm should be considered. These dimensions allow for space-saving installation even in tight vehicle environments. Thanks to the flexible connection options via Pre-In and Speaker-In inputs, the AS4120 is compatible with almost all original and aftermarket head units. Regardless of whether the vehicle is equipped with factory speakers or retrofitted brand models, the minimum supported impedance of 2 Ohm and the robust performance values ensure compatible integration into almost any audio system.

What input options are available on the AS4120 Amplifier?

The AS4120 Amplifier offers you a variety of input options to ensure a seamless connection to different audio sources. With both pre-amplified (Pre-In) and high-level (Speaker-In) inputs, it is flexible to use. This configuration allows you to easily connect both OEM and aftermarket audio units. The input sensitivity ranges from 0.2 V to 5 V RMS, supporting a wide range of signal strengths and enabling adaptation to different sources. This versatility makes the AS4120 an excellent choice for various vehicle audio systems.

How efficient is the heat dissipation system of the AS4120?

The AS4120 features an optimized heat dissipation system specifically designed to effectively manage the generated heat. The heat flow is directed to the heat sink and then efficiently dissipated through the sides of the amplifier. This prevents overheating of the internal components and ensures lasting performance even at high volumes. This thoughtful design helps secure the longevity of the electronic components, especially when you install the amplifier in tight or poorly ventilated vehicle environments that could cause additional heat buildup.

What advantages does the Crossover system of the AS4120 offer?

The Crossover system of the AS4120 is a crucial feature that allows you to precisely adjust and optimize the sound. It includes both low-pass and high-pass filters in the range of 50 Hz to 750 Hz with a filter depth of 12dB/Octave. These filters enable targeted crossover, which is particularly critical when using Subwoofers and satellite speakers. The Crossover system is fully bypassable, meaning you can play the original signal without interference from filters if needed. This flexibility allows for optimal adaptation to different speaker configurations.

Can the AS4120 also be used as a mono amplifier?

Yes, the AS4120 can be used as a mono amplifier, giving you the option to use it in both stereo and mono configurations. In a 3-channel setup, for example, the amplifier can use two channels for the front speakers and the bridged mode for a Subwoofer. This allows you to flexibly adapt the amplifier to the specific requirements and available speaker systems. The ability to operate the amplifier bridged at 4 Ohm with 260 Watts RMS underscores its versatility in use.

How does the bass boost affect the sound quality of the AS4120?

The integrated bass boost of the AS4120 Amplifier allows for an increase in bass level of up to +12 dB at 45 Hz, which is particularly beneficial for bass enthusiasts who want to enhance low frequencies without affecting other frequency ranges. The targeted boost of these bass frequencies can add extra punch and depth to your audio system, especially when listening to music with strong bass like electronic or hip-hop tracks. The depth of intervention remains under your control with the option for step adjustment to achieve the desired sound balance.

What technical parameters determine the reliability of the AS4120 Amplifier?

The AS4120 Amplifier from Audio System Italy impresses with several technical parameters that define its reliability. The use of high-quality materials and components ensures stability and durability. The minimized load capacity of 2 Ohm allows operation with various speaker configurations without compromising power stability. The input sensitivity of 0.2 V to 5 V RMS provides flexibility in signal input. The dimensions and weight of 4.60 kg are also chosen to ensure that the amplifier offers a durable hardware structure that guarantees stable operation under common usage conditions.

What are the dimensions of the AS4120 and how do they affect installation?

With dimensions of 385 mm x 52 mm x 230 mm, the AS4120 Amplifier offers a compact design that ensures easy installation, even in vehicles with limited space. These dimensions are chosen to ensure optimal placement without significantly affecting the interior. Whether you want to mount the amplifier under a seat or in the trunk, the compact dimensions support flexible positioning for the best possible performance output.
