Audison SR 1.500 Mono Class-D Amplifier

Introducing the enhanced Audison SR 1.500 (1000 W 1 Ω) Mono D-Class Amplifier, originally released in 1988 and continuously upgraded with cutting-edge technologies.

Our expert team at Audison, located in Potenza Picena, Italy, dedicated extensive time and resources to create the new SR line. Through the use of cutting-edge amplification technology and thorough double-blind listening tests with experts and enthusiasts, the team ultimately implemented the groundbreaking ADT (Audison D-Class Technology) in the entire range. This resulted in compact amplifiers that deliver the renowned audio performance that Audison is known for.

EDGELESS DESIGN
The Audison style center has carefully crafted the electronics design, creating a slim and efficient amplifier. Constructed with extruded aluminum and curved edges, this compact product is easily installed in tight areas. Furthermore, the extensive heat sinks on both sides eliminate the necessity for internal cooling fans, reducing noise and dust buildup.

COMPLETE CONTROLS ON UPPER PANEL
As is customary, the SR amplifiers showcase their versatility by featuring a comprehensive filter section on all models, perfect for all types of audio system setups. The controls, safeguarded by a smooth aluminum panel, are situated on the top of the amplifier for effortless access, even after installation. If the system incorporates an Audison bit processor, the entire filter section can be disabled.

 
By incorporating Audison USS technology (Universal Speakers Simulator) into the high-level inputs, the SR amplifiers can also be connected to OEM sources with the "speaker load detection" function. This allows for monitoring of a low-impedance load, enabling proper audio outputs. USS is a dynamic load circuit that initially presents the OEM output channel with a low load, ensuring future-proof compatibility. Once activated, a higher load is introduced, maintaining proper damping for Class D outputs without causing current or heat issues.

LIMITLESS CONNECTIVITY

All Audison SR1.500 Mono Class-D Amplifiers come with high-level balanced inputs for connecting to both OEM Head Unit speaker outputs and low RCA levels for aftermarket ones. The use of high-level inputs also allows for the use of the ART function (Automatic Remote Turn-On / Off) which can be controlled by the head unit switch-on button. Additionally, the amplifiers can be controlled remotely through the IN / OUT socket, allowing for multiple cascaded amplifiers to be switched on simultaneously when needed. The SR 1.500, SR 4.300, and 4.500 models also have the ability to recreate the PRE-OUT signal through the Speaker-IN input, making it compatible with OEM sources that only have amplified outputs and allowing for system expansion.
