1x1000W Class D Amplifier

Download Product Data Sheet

This is a single channel High Efficiency Full Bridge Class-D amplifier module based on the patented UCD modulation technique, with newly introduced improvements for better audio performance.  UCD is an analog modulation technique for class-D amplifiers based on a free running oscillator. The oscillation conditions are created by a phase shift in the feedback loop between the output terminals to the input of the amplifier.

Audio Power Amplifier Module. High-quality, reliable, efficient. The Heliox AMP1x1000F/4 audio power amplifier module is the perfect solution for high-power active speakers. With its unparalleled musicality, unlimited power and small dimensions it will be applicable in any high-end audio system.

The feedback signal is taken directly from the output terminals of the amplifier, thereby including the output filter in the control loop, virtually eliminating the influence of the filter on the audio performance. Advantages are a very low output impedance, a stable operation over a broad range of load impedances from 1Ω to  and the absence of a Zobel network, so that there is no restriction to output power and duration in the high audio frequency range.

Proportional feedback loop

The feedback loop of the UCD amplifier is proportional in the range of audio frequencies, as opposed to the often-applied integrating feedback. This gives the UCD amplifier an excellent audio performance over the full audio bandwidth.
