Hallo Leutz,
mit dem geschalteten Endstufenmodul UCD400 möchte ich weitermachen. Es ist der größere Bruder des UCD180. Bei fast identischen Daten liefert diese Modul 400W an 4 Ohm.

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.
Features
• 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
• HxR regulator ready
Applications
• Monitor loudspeakers for recording and mastering studios
• Audiophile power amplifiers for professional and consumer use
• Public Address systems
• Home theatre systems
• Active loudspeakers
• Also available with pre-mounted HxR regulators.
Technology
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.
