Orban 674-A (c. 1981)
Not much is documented about the Orban 674-A. The Archive's best source is a review in Modern Recording (October 1981, p.69), which introduced the 674A as a stereo equalizer. It is the two-channel version of Orban's 672A, a mono unit that Modern Recording & Music had reviewed in November 1979. The same article described the setup moves the equalizer was meant to handle: a gradual bass boost below the speaker's resonance to gain another fraction of an octave, a smooth upper-midrange dip to tame a harsh-sounding midrange driver, and a gently rising top end to liven up the tweeter.
The review's specifications (October 1981, p.71) give a list price of $1,179. The unit is 19 inches wide, 5¼ inches high and 5¼ inches deep behind the panel, and it weighs 13.5 lb. The earlier page also noted that the unit was designed to work with two-conductor shielded cable.
Past those pages, the record thins out fast. An Orban line listing in Recording Engineer (October 1983, p.149) shows the company's pro lineup of the period - a spring reverb, a stereo synthesizer, a compressor/limiter, and a gated compressor/de-esser. No further dedicated 674-A coverage has turned up in the Archive's holdings. Its production run, later revisions, and collector history are undocumented.
