UcD™ is a proven Class D amplifier technology developed over more than two decades ago and widely adopted across DIY, HiFi and professional audio applications due to its solid measured performance and cost effective implementation.
UcD™ modules are used in a broad range of audio products and installations. The design allows manufacturers and system integrators to achieve reliable performance across different power levels and use cases.
Flat frequency response
The amplifier modules are designed to maintain a flat frequency response independent of load impedance. Distortion behaviour remains largely consistent across the frequency range, and radiated and conducted electromagnetic interference is kept at low levels through circuit topology and PCB layout.
The amplifier architecture is based on a phase shift controlled self oscillating loop with feedback taken directly at the loudspeaker output. This control method supports stable operation across varying load conditions and contributes to predictable electrical behaviour in practical audio systems.
The UcD family follows a modular system design. Half bridge and full bridge amplifier modules are offered separately and are intended to be combined with dedicated switch mode power supplies. This approach allows system designers to select amplifier and power supply combinations according to channel count, power level and application requirements.
UcD™ amplifier modules are intended for professional audio applications that require multiple amplifier channels, such as multichannel power amplifiers, line array systems and other scalable audio installations. The modular structure supports efficient system design and straightforward integration in applications with higher channel density requirements.
To this date UcD™ is still manufactured and sold by Hypex as the most cost-effective solution.
