デンオン カタログ・昭和58年4月
A3 sheet folded in half, about a single unit - the DENON DE-70 graphic equalizer at ¥69,800. DENON calls it a “dynamic sound equalizer”: on top of a 12-band graphic with independent left and right channels (center frequencies 16Hz-32kHz, ±12dB adjustment) it adds a dynamic gate and an expander gate that widen the source’s dynamic range up to +12dB. The inner spread is a detailed walkthrough of uses from professional mixers: liven up FM and music tape, make a recording for headphones or car stereo, kill speaker boom while tuning a P.A., pull a quiet record out of its hiss. The equalizer knobs glow with two-color LEDs (orange for the left channel, green for the right) under a smoked cover, and the back carries the spec table and the internal block diagram.
