Teac GE-20 2-Channel 10-Band Stereo Graphic Equalizer, Japan
Ten ISO-standard bands per channel from 31.5 Hz to 16 kHz at ±12 dB, with separate left and right sliders and switchable VU metering. Filters at 31.5 Hz and 16 kHz roll off rumble and ultrasonic noise without touching the audible band, and an EQ defeat switch lets you A/B against flat. Made in Japan, 1978; serviced, good cosmetic condition.
Yamaha Q2031 Dual 31-Band Graphic Equalizer – Made in Japan, 2U
Thirty-one bands per channel on ISO third-octave centres, 20Hz to 20kHz, on two fully independent channels — fine enough to pull a single room mode down without touching what sits either side of it. A range switch halves boost and cut to ±6dB for careful work, and the high-pass filters sweep from 20 to 200Hz. Balanced XLR and 1/4-inch throughout, 2U rack. Condition good.
Nikko EQ-II 6-Band Stereo Graphic Equalizer Made in Japan
Six sliders a channel at 40Hz, 125Hz, 400Hz, 1.25kHz, 4kHz and 12.5kHz, each with 12dB of boost or cut, and a bypass switch for an instant A/B against the unprocessed signal. 0.01% distortion, better than 100dB signal to noise, 10Hz to 30kHz — it adds nothing of its own. Built in Tokyo between 1977 and 1981. Excellent condition, fully tested.
Technics 7-Band Graphic Equalizer – Made in Japan SH-8027
Seven bands a channel — 63 Hz, 160, 400, 1 k, 2.5 k, 6.3 k and 16 kHz — on illuminated red sliders you can read in a dark rack. Two RCA pairs in and out, a built-in mains cord, and an unswitched 150-watt accessory outlet on the back. Made in Japan somewhere between 1980 and 1985. Level 1 serviced here.
Nikko EQ-500 6-Band Stereo Graphic Equalizer Made in Japan
Six sliders a channel at 40, 125, 400, 1,250, 4,000 and 12,500 Hz, each giving 12 dB of cut or boost in 2 dB steps. Distortion is 0.01%, signal-to-noise better than 100 dB, response 10 Hz to 30 kHz — it adds nothing of its own. Bypass switch and a pre/post-EQ tape loop. Made in Japan. Cosmetic condition fair; fully tested and working.
Sansui SE-7 Black 10-Band Stereo Graphic Equalizer, Japan
A black-faced ten-band-per-channel graphic equalizer from Sansui's strongest years, built in Japan between 1979 and 1982, and a far more serious instrument than the tone controls it was meant to replace.
