ELAC STS-322 (c. 1967)
Little is documented about the ELAC STS-322. Here is what the record shows. It was a stereo phono cartridge marketed under the name "Studio Stereo Professional." Audio (November 1967, p.78) ran an Equipment Profile of it. The profile, continued from p.58, listed the manufacturer's frequency-response specification as 20-20,000 Hz ±2 dB.
Beyond that, almost nothing survives. The January 1969 issue of Audio (p.56) profiled a related Elac STS-444-E stereo cartridge. That suggests the STS-322 was part of a line of ELAC STS cartridges in the late 1960s, but the relationship between the two models is not documented. No pricing, measured test results, or design details for the STS-322 have been found in the period record.
