19877 📃
Staple-bound booklet, 12 pages - SONY CD player catalog for October 1987. The lineup is split into three tiers: the new ES series with flagship CDP-557ESD (18-bit DAC, 8x oversampling, ¥180,000) alongside CDP-337ESD and CDP-227ESD; a mid-range row with CDP-950 and CDP-750 featuring Custom File (programmable track notes); and the compact CDP-M55 with remote. The changers get dedicated spreads - the five-disc CDP-C5M and the ten-disc CDP-C10 with magazine loading. The central technology spread presents the new ES generation under the concept of “stillness and motion”: linear laser carriage drive, 18-bit converter and 8x digital filter as the new standard.
- 18ビット・リニアD/Aコンバーター - 18-bit linear DAC - extended dynamic range over the 16-bit standard; featured in CDP-557ESD and CDP-337ESD
- 8倍オーバーサンプリング・デジタルフィルター - 8x oversampling digital filter - smooths quantization artifacts, reduces demands on the analog output filter
- カスタム・ファイル - Custom File - stores user-defined data per track: notes, indexes, playback programs; implemented in CDP-950 and CDP-557ESD
- リニア・スケイティング - linear laser carriage drive - carriage moves along linear rails without a pivot arm, ensuring stable optical path
