KYOCERA DA-910 (1984) | Better Sound Based on Ceramics

 

The Kyocera (Kyoto Ceramic) DA-910 Remote Control Compact Disc Player stops vibration in its track. How? With ceramics technology-Kyocera's innovative method of ensuring steady laser tracking-immune to vibrations. The bottom line: total purity of sound. Why ceramics? They're rigid and inert, so they provide uncommon stability and resistance to mechanical vibrations from audio feedback. They're non-ferrous, so there are no chassis eddy currents to cause electrical hum. The handsome ceramic-compound resin base of the DA-910 CD player is actually the chassis-supporting and housing all components and isolating vibration. Resonance from the cabinetry is almost non-existent. But Kyocera doesn't stop there. Digital audio's technical requirements demand un-precedented circuit capability so we use fine ceramics throughout to further conquer vibration. For example, all discrete hi tolerance audio components and the 3rd order Besselle analog filters are ceramic encased. There are other material differences. In-stead of an ordinary laminated E frame, Kyocera use a solid ferrite cutlass core power transformer to cut eddy currents, minimize flux leakage and improve voltage regulation. And instead of ferrous metals, Kyocera use 100% aluminum and zinc chassis construction including a diecast laser head and a precision disc drive mechanism.
