NIKKO Audio Company was a Japanese electrics company that made lots of interesting audio gear (usually with a compact form factor) from the sixties through the eighties. They got out of the consumer audio business and have later focused on......RC model cars, where they now are the world leader. This hard-to-find NIKKO EQ-II is an advanced graphic equalizer made in 1980 in great condition and still fully functional. Six slide controls on the front panel let you boost or attenuate frequency response at precisely the point you desire, helping to correct for peaks and dips in the frequency response of the reproduced sound. Each control provides up to 12dB of boost and attenuation, lets you make music sound most natural for your listening room. The unit connects with ease to an amplifier or receiver, or, if you wish, to a tape deck. Specifications: Frequency response: 10Hz to 30kHz Signal to Noise Ratio: 100dB Total harmonic distortion: 0.01% Control Range: ± 12dB Frequency Bands: 40, 125, 400, 1.25K, 4K, 12.5KHz Dimensions: 420 x 96 x 329mm Weight: 4850 grams Year: 1980 Height: 10 cm Width: 42 cm Length: 30 cm With tape monitoring function.
