Nakamichi TA-30

Little is documented about the Nakamichi TA-30. The model shows up in the period press. HiFI-Stereo (1979, p.116) ran a listing that mentions a stereo graphic octave equalizer with ten elements (32 Hz through 16 kHz) and a level control range of ±10 dB. Frequency response is given as 5 to 70,000 Hz (+0/-1 dB). The same fragment suggests a compress/expand ratio of 2:1 and tracking accuracy of ±1 dB per 20 dB, which may point to some form of dynamic range processing in the unit. The following year, HiFI-Stereo (1980, p.7) carried a brief mention of the TA-30 in what appears to be an accessories or new-products roundup. The surrounding text is too fragmentary to pull any real detail from it.

Past those two period references, the record is essentially empty. No specifications, production years, original price, or design details have surfaced. The TA-30's name suggests an amplifier or receiver in Nakamichi's late-1970s lineup, but that is inference, not documentation. If you own a TA-30 or have a service manual, the archive would welcome the contribution.
