Hypex Universal Class D
Hypex UcD amplifier modules are self-contained high-performance Class-D amplifiers intended for a wide range of audio applications, ranging from 'public address' systems to ultrahigh-fidelity replay systems for studio and home use. Chief distinguishing features are flat frequency response irrespective of load impedance, nearly frequency-independent distortion behaviour and very low radiated and conducted EMI. Control is based on a phase-shift controlled self-oscillating loop taking feedback only at the speaker output.
2003 saw the start of a migration of all products to Class-D. For this, a licence deal was closed with Philips for the "Universal Class D" circuit. Realising the market potential of the circuit, Hypex decided not only to use the technology in completed subassemblies, but also to sell bare amplifier modules to the open market. The UcD180 and UcD400 modules have quickly established themselves as the new standard, both in terms of measured and subjective performance.
