The Kyocera DA-910 is a CD player designed to transform music information from CDs into sound with minimal loss. It incorporates a base chassis made from a composite of fine ceramic and resin, known for its high rigidity and excellent vibration damping characteristics. This structure supports main components like circuit boards and power transformers, significantly reducing internal vibrations. With height-adjustable feet for stability, the player is engineered to resist external vibrations effectively. The device features an FCL module that shields delicate analog circuits from pulse noise, shielding elements from thermal distortion. The digital circuit includes a DA conversion system with digital filters and independent left/right DA converters, raising the PCM signal frequency by a factor of four to 176.4 kHz. It incorporates a low-order analog low-pass filter following DA conversion to preserve phase and group delay characteristics of the music signal. The design minimizes signal path complexity by ensuring non-contact components and eliminating muting relays and output volume controls, improving sound quality. A discrete DC amplifier configuration connects the DA converter directly to the output terminal, enhancing low-frequency phase characteristics while stabilizing amplifier operation. Separating the analog and digital power supplies further mitigates digital noise interference. Specialized LC-OFC wiring is used, which has fewer crystal boundaries to minimize signal degradation. The DA-910 encompasses features such as index search, program memory for up to 20 songs, repeat, memory skip, pause, memory call, and a remaining time display. Its specifications include a playback frequency band of 5 Hz to 20 kHz with ± 0.5 dB accuracy, a signal-to-noise ratio of 90 dB or more, dynamic range and channel separation exceeding 90 dB, and total harmonic distortion of 0.007% or more across 20 Hz to 20 kHz.
