SD-NX10, SD-CX1, SD-FX1 digital audio systems
Article Abstract:
Sharp Corp introduces its SD-NX10, SD-CX1 and the SD-FX1 digital audio systems each feature 1-bit amplifiers. The amplifiers sample 2.8 million signals per second, around 64 times the rate of CD sampling. They employ seventh-order delta sigma modulator ICs for stable amplication of music signals. A circuit for long playing and recording allows systems to record up to 320 min on a single 80-min MiniDisc. Both the SD-NX10 and SD-FX1 have thin design, while the SD-CX1 has a transparent design.
