New, pre-packaged.

Audison SR 4.300 is a 4-channel amplifier with crossover and high power enclosed in ultra-compact dimensions (85 W x 4 4Ω) of the SR line, improved thanks to the full use of the capabilities of the latest amplification devices. After numerous listening tests with professionals and enthusiasts,The research and development team of Audison decided to use a new class D technology in this line of amplifiers,called ADT (Audison D-Class Technology),which allowed for a significant reduction in their size,while maintaining the sound quality characteristic of each Audison project.

When it comes to electronic design, the Audison SR 4.300 has been designed with attention to every aesthetic and functional detail, resulting in a compact amplifier made of extruded aluminum with rounded corners, which facilitates the installation of the product in narrow spaces.

The controls, protected by a satin aluminum panel, are located on the top panel of the amplifier, so they are easily accessible from above, even after the product is installed. When the system includes the Audison bit processor, the filter section can be turned off completely.

As for the electronic design, the Audison SR 4.300 has been designed with attention to every aesthetic and functional detail, resulting in a compact amplifier made of extruded aluminum with rounded corners, which facilitates the installation of the product in narrow spaces.

Thanks to the large heat sinks on the two shorter sides of the amplifiers, there is no need for internal cooling fans, which often cause noise and dust accumulation. According to tradition, SR amplifiers confirm their calling for versatility, because in all models they contain a complete filter section, suitable for any type of audio system configuration.

Thanks to the integration of Audison USS (Universal Speakers Simulator) technology in high-level inputs, SR amplifiers can also be conveniently connected to OEM sources equipped with a “speaker load detection” function that monitors the presence of low-impedance load, enabling audio outputs. Audison SR 4.300 enables multiple connectivity.

All models have balanced high-level inputs to connect to the speaker output of the OEM and RCA low-level radio for aftermarket speakers. When using a high-level input, the ART (Automatic Remote On/Off) function can be activated to control the switching on of amplifiers using the power button of the radio player. In addition, an IN/OUT remote control socket is available, allowing you to control multiple amplifiers in a cascade system that turn on when needed.

Through the PRE-OUT signal, via the Speaker-IN socket, it is possible to connect the amplifier with OEM sources that have only reinforced outputs, which allows you to expand the system.

Key Features:

• Sleek and functional design with rounded corners for minimal space and easy installation.
• Built-in USS (Universal Speakers Simulator).
