Hefty 12-page catalog for Pioneer’s UA Series - a modular lineup of separate components, 18 items total. Tuners from TX-100 at ¥60,000 down, integrated amps from the 170-watt SA-100 at ¥80,000 to SA-50A at ¥25,000, separates SC-100/SM-100 for those building a system piece by piece. A separate story - electronic crossovers SF-70 and SF-90 for multi-amping, and the series flagship SD-100 tuner-amplifier at ¥108,000. There’s even a QL-60 quadrizer for pseudo-4-channel sound.
- 全段直結方式 - direct-coupled circuit throughout - all stages without coupling capacitors, frequency response 5 Hz to 80 kHz
- SEPP-OTL方式 - output stage without transformer using silicon power transistors
- エレクトロニッククロスオーバーネットワーク - active electronic crossover - signal band splitting before the power amplifiers
- クオドライザー - Pioneer's proprietary technology for expanding stereo to 4-channel sound
- ダンピングファクター切換 - switchable damping factor for controlling speaker cone control stiffness
- E-E帰還方式 - three-stage direct-coupled circuit with emitter-to-emitter feedback
