D1k Class-D High Efficiency Power Amplifier with Loudspeaker Management

D-series represents the latest technology in amplifier design. Extremely high fidelity sound with frequency-independent harmonic distortion performance, high efficiency class-D design and very low total weight. D-series amplifiers are also fitted with fixed system controllers for specific loudspeaker including high-pass and low-pass filters, parametric eq and state-of-the-art optical limiter circuit.

D1k features switch-mode power supply with over current and over voltage protection system and optimized low noise cooling system.
