19889 📃
Technology booklet for the SONY ES lineup, February 1988 - essentially the same as the fall 1987 edition: amplifiers TA-F555ESXII, TA-F333ESXII, TA-F222ESX, tuners ST-S333ESXII and ST-S222ESX, and the digital surround processor SDP-777ES at ¥79,800. Half the booklet covers the technologies: G-Chassis zinc die-cast construction, S.T.D. Circuit for the amplifiers, and the four-stage Wave Optimizer (SST, WOIS, WODD, WODSD) for the tuners. A dedicated spread explains Pro Logic and how the SDP-777ES derives four-channel Dolby Surround from a standard stereo signal.
- Gシャーシ (Acoustically Tuned Gibraltar Chassis) - G-Chassis (Acoustically Tuned Gibraltar Chassis) - zinc die-cast chassis with acoustic tuning: monolithic construction suppresses cabinet resonances and improves sound clarity
- S.T.D.回路 (Spontaneous Twin Drive Circuit) - S.T.D. Circuit (Spontaneous Twin Drive Circuit) - dual output stages working in tandem to expand dynamic range when reproducing CD sources
- シンプル&ストレート伝送 (Simple and Straight Transfer) - Simple & Straight Transfer - shortest possible signal path: minimal switches and buffers in the circuit
- Wave Optimizer Technology - Wave Optimizer Technology - Sony's proprietary radio signal optimization for ES tuners, from antenna to stereo decoder
- SST (Super Sound Tracing Circuit) - SST (Super Sound Tracing Circuit) - front-end circuit that reduces intermodulation distortion from strong out-of-band signals
- WOIS (Wave Optimized IF System) - WOIS (Wave Optimized IF System) - optimized IF stage with precisely tuned filters to eliminate waveform envelope distortion
- WODD (Wave Optimized Direct Detector) - WODD (Wave Optimized Direct Detector) - direct detector bypassing the conventional discriminator, reducing phase distortion
- WODSD (Wave Optimized Digital Stereo Decoder) - WODSD (Wave Optimized Digital Stereo Decoder) - digital stereo decoder with waveform optimization using digital pilot tone processing
- PRO LOGIC (ドルビーサラウンド) - Pro Logic (Dolby Surround) - matrix surround decoding: the SDP-777ES extracts four-channel Dolby Surround from standard stereo recordings
