1987 (Nov.)
Initially sold for ¥150,000

Professional digital equalizer with graphic EQ, parametric EQ, band pass or band reject programs, notch filters, and dynamic filters controlled by LFO or manually with a foot switch. It has XLR stereo inputs and outputs only.

The great detail and flexibility offered by the DEQ7 is all managed through a very restricted amount of buttons and a small LCD screen, which albeit being very precise they're surely not as intuitive and quick to use as physical faders.
