UcD400HG with HxR
The UcD400HG 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 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.APPLICATIONSAudiophile power amplifiers for professional and consumer useFEATURESPop-free start and stop controlDifferential audio inputOvercurrent and over voltage protectionNo compromise componentsLM4562 buffer OpAmpHxR12 mountedUltra-low noiceImproved on-board buffer supplyCONTENTS OF PACKAGINGUcD400HG with HxR amplifier moduleMounting set UcDManualManual HxRRECOMMENDED ADDITIONAL PARTSPower supply SMPS400A400UcD signal cable

The NC400 packs a feature set never seen before in a modular amplifier product. The NC400 module's audio performance sets new standards,regardlessof operating class or circuit technology. Distortion (THDand IMD) over the full audio and power range is negligible, typically below 0.0007%. Distortion at listening levels (1W) is unmeasurable. This amp adds neither dirt nor fairy dust.
