Audison SR 4.300 4-channel amplifier with crossover and great power packed in ultra-compact dimensions (85 W x 4 @ 4Ω)

SR line, perfected by fully exploiting the functionalities of the most recent amplification devices. After numerous listening tests with professionals and enthusiasts, the Audison research and development team decided to adopt a new class D technology called ADT (Audison D-Class Technology) for this amplifier line, which made it possible to considerably reduce its size, completely preserving the audio performance that characterizes every Audison project. As for electronic design, every aesthetic and functional detail of the Audison SR 4.300 has been taken care of, obtaining a compact amplifier made of extruded aluminum with rounded corners that facilitates product installation in confined spaces.

Thanks to the generous heat sinks on the two short sides of the amplifiers, internal cooling fans are not necessary, which are often a cause of noise and dust accumulation. As per tradition, SR amplifiers confirm their versatility by including a complete filter section on all models, suitable for any type of audio system configuration. The controls, protected by a satin aluminum panel, are located on the upper panel of the amplifier, to be easily accessible from above even after product installation. When the system includes an Audison bit processor, the filter section can be completely excluded.

Audison_USS

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

Audison SR 4.300 allows multiple connections

All models are equipped with balanced high-level inputs for connection to the speaker outputs of the OEM main unit and low-level RCA for after-market ones. When using the high-level input, the ART function (Automatic Remote Turn-On/Turn-Off) can be enabled to control the amplifiers' power with the main unit's power button. In addition, there is a Remote IN/OUT jack to allow control of multiple amplifiers in cascade that turn on when needed. Through the PRE-OUT signal using the Speaker-IN input it is possible to interface the amplifier with OEM sources equipped with only amplified outputs, allowing system expansion.
