Hypex UcD250LP(OEM), 250W class D amplifier module

Description

High Efficiency Power Amplifier Module (Low Profile OEM Version)
Description
The UcD250LP (Low Profile Low Profile OEM version) amplifier module is a self-contained high performance class D amplifier
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 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 output
Highlights
Flat, fully load-independent frequency response, Low output impedance
Very low, frequency-independent THD, Very low noise, Fully passive loop control
Consistent top performer in listening trials
Features
Extended voltage headroom, Pop-free start and stop control
Differential audio input, DC-fault detection
Over-current and over-voltage protection, Weight: 55 g / Height: 26mm
Applications
Monitor loudspeakers for recording and mastering studios
Audiophile power amplifiers for professional and consumer use
Public Address systems, Home theater systems, Active loudspeakers
