General description

What do you look for in a power amplifier? Bet it's the sound. Hypex UcD™ amplifier modules are designed from the ground up for true fidelity. Available in 180W, 400W and 700W variants, they represent a new generation of switching power converters truly performing as amplifiers.


• Flat, fully load-independent
frequency response
• Low output impedance
• Very low, frequency-independent
• 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, shortcurrent and
• DC/AC-coupling selectable
• Fits in a 2HE case when mounted on
its side
• 4-layer PCB design

• Monitor loudspeakers for recording
and mastering studios
• Audiophile power amplifiers for
professional and consumer use
• Public Address systems
• Home theatre systems
• Active loudspeakers


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.
