1999 SM-SX100 1-Bit Amplifier

Sharp released a world first, the 1-Bit Digital Amp with 2.8-MHz sampling and 7th order delta-sigma modulation. In addition to ultra-realistic sound that recreates the most minute details of the music's atmosphere, 1-Bit technology also allows audio products to be made smaller and more energy efficient. 1-Bit was immediately called the next-generation amplifier technology that offers almost the most faithful sound reproduction ever.
