デンオン カタログ・昭和55年10月
An A3 sheet folded in half, covering a single integrated amplifier - DENON PMA-970 (¥200,000), the PMA series flagship as of October 1980. The spread breaks down the design: Direct A circuit (ダイレクトAアンプ) with no capacitors in the signal path, pure Class A output stage (純A級), Super Equalizer (スーパーイコライザー) spanning from MC input to speaker output, DC Servo for offset stabilization, and RIAA correction within ±0.2 dB. The back page includes a PMA-970 block diagram and the companion components from the same lineup: preamplifier PRA-2000 (¥200,000) and power amplifier PCA-3000 (¥350,000).
