Audison SR 1.500 Amplifier

Audison SR 1.500 Mono Channel Amplifier | 1000W RMS Power | D-Class | 1Ω Stable | ADT Technology | Compact & Versatile

The Audison SR 1.500 Amplifier is a high-performance mono D-Class amplifier designed for subwoofer applications, delivering a robust 1000W RMS at 1Ω. Built for precision, efficiency, and compact installation, this mono amplifier combines advanced engineering with cutting-edge ADT (Audison D-Class Technology) to achieve exceptional audio performance without compromising space or flexibility.

Engineered for seamless integration into both aftermarket and OEM audio systems, the SR 1.500 comes equipped with a full crossover section, balanced high-level inputs, and low-level RCA inputs. Its compact body is crafted from extruded aluminum with rounded corners, making it ideal for tight installation spaces. Side-mounted heat sinks provide efficient passive cooling without the need for noisy internal fans, reducing dust accumulation and enhancing durability.

For OEM systems, the built-in USS (Universal Speakers Simulator) ensures flawless connection with head units that feature speaker load detection. When using high-level inputs, the ART (Automatic Remote Turn-On/Off) function enables automatic power control in sync with the vehicle’s audio system. Additionally, the Remote IN/OUT socket allows you to control multiple amplifiers in cascade configurations, while the PRE-OUT capability supports easy system expansion.

For added control, the optional VCR-S2 subwoofer remote control lets users fine-tune subwoofer output (-20 dB to +6 dB), tailoring the bass response to personal taste and musical genres.

Advanced Technologies

🔸 ADT – Audison D-Class Technology

Audison’s proprietary ADT architecture leverages a switching frequency twice as high as that used in typical Class D amplifiers. This reduces electromagnetic interference (EMI), pushes switching noise far outside the audible range, and enhances overall audio clarity. The use of 4th-order analog low-pass filters—instead of the simpler 2nd-order filters found in competing designs—ensures a cleaner signal, protects high-frequency drivers, and minimizes phase shift. This high-performance filtering requires high-precision components, making the SR 1.500 a top-tier choice for critical subwoofer applications.

🔸 USS – Universal Speakers Simulator

Integrated USS technology enables reliable connections to OEM head units that detect speaker load. This ensures audio output even when replacing factory speakers with low-impedance aftermarket equipment.

🔸 All Channels Driven Design Philosophy

While the SR 1.500 is a mono amplifier, it still follows Audison’s high-power delivery standards. The internal power supply is built to handle peak loads without compromising performance.
