AB performance from a class D platform

Employing cutting-edge NCORE® Class D amplifier modules, these amplifiers are meticulously engineered with the highest precision and attention to detail. The high-end Class D modules ensure ample power with exceptional clarity, detail, and precision in sound reproduction. Experience well-controlled yet impactful low frequencies, paired with open, clear high frequencies typical of classic AB designs.

To provide a comprehensive and visually appealing solution, we introduce the 4150 Amplifier. This amplifier closely mirrors the performance of class AB amplifiers and boasts four independent channels each delivering 150W on 8 ohm (4 x 250W on 4 Ohm). The chassis and finish of the 4150 amplifier align with the standards set by our loudspeaker systems.

Where Precision Harmonizes: Unmatched Sound.

The chief distinguishing features include a flat frequency response regardless of load impedance, nearly frequency-independent distortion behavior, and minimal radiated and conducted EMI. Control is facilitated through a phase shift-controlled self-oscillating loop, with feedback obtained solely at the speaker output.

The primary SMPS (Switched-Mode Power Supply) providing power for the amplifier is a compact, high-power, highly efficient, regulated half-bridge converter with synchronous rectification on the main output rails. These characteristics render this technology ideal for powering Class D audio amplifiers.

Harmonized design that perfectly matches our loudspeakers

Designed in a minimalistic fashion we offer the best possible DSP loudspeaker management system available today. Allowing complete freedom when it comes to pair your favorite amplifier the 3960 DSP we also introduce the 4150 Amplifier that has identical external dimensions and look.
