UcD102 OEM
The UcD102 amplifier module is a dual channel 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 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. This module is perfect for stereo amplifiers and multichannel amplifiers up to 16 channels.ApplicationsMonitor loudspeakers for recording and mastering studios Audiophile power amplifiers for professional and consumer use Public Address systems Home theatre systems Active loudspeakers FeaturesFlat, fully load-independent frequency response Low output impedance Very low, frequency-independentTHD Fully passive loop control Consistant top performer in listening trials Runs on unregulated +/- rails Pop-free start and stop control Thermal protection DC-fault detection Overcurrent and over voltage protection Contents of packagingUcD102 OEMManual
