Klark Teknik SA-30

Little is documented about the Klark Teknik SA-30. The only substantial period reference found so far is Studio Sound (October 1979, p.68), which covered the unit in the second part of a two-part survey of effects equipment. The review describes an effects unit with six gold-plated leaf-spring momentary buttons. The compressor section had ratios of 1.5:1, 2:1, 5:1 and a 20:1 limit. There was also an expander, and the metering switched between output level and gain reduction on either channel.

The same passage mentions a system at approximately £350 with a multiple-spring design, an input limiter, input/output level controls, and variable high and low frequency EQ. The surviving OCR doesn't make it clear whether that system is the SA-30 itself or a separate unit reviewed alongside it. Production years, original price, and full specifications are otherwise undocumented.
