Module amplificateur Hypex UcD180 ST [Hypex UcD180 ST] Avis/Critiques The UcD180 amplifier module is a self-containes high performance class D amplifier intended for a wide range of audio applications, ranging from Public Adress 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 distorsion behavior and very low radiated and conducted EMI. Control is based on a phase-shift controlled self-oscillating loop taking feedback only at the speaker out.

Manuel d'utilisation
Points Forts :
Flat, fully load-independent frequency response Low output impedance Very low, frequency-independent THD Very low noise Consistent top performer in listening trials including class A and SET amplifiers Runs on unregulated +/- rails Pop-free start and stop control Differential audio input Overcurrent and overvoltage
Applications :
Monitor loudspeakers for recording and mastering studios Audiophile power amplifiers for professional and consumer use Public Address systems Home theatre systems Active loudspeakers

Technologie :
The UcD™ circuit is based on phase-shift controlled self-oscillation, with only a single voltage feedback control loop taking off at the loudspeaker terminals. The control function is constructed fully out of passive components, with only the comparator standing in for gain.
