ADC Sound Shaper SS-117EX
Little is documented about the ADC 117EX on its own. What survives comes from a single period advertisement for ADC's Sound Shaper line. That ad was placed by ADC in Audio (1986, p.129). It presented the SS-117EX as a graphic equalizer with a built-in spatial expander. The listener could adjust sound octave by octave from 20 Hz to 20 kHz and also widen the stereo image. The ad used the same tagline and layout as other Sound Shaper promotions of the era, and it positioned the SS-117EX as the model that added spatial enhancement to the basic equalizer function.
Beyond that promotional mention, no further specifications — number of bands, frequency response, distortion figures, dimensions, or price — have been located in surviving documentation. The model does not appear in the few available ADC dealer price lists or catalog sheets from the mid‑1980s, and no service manual or user guide has surfaced.
What the record shows is a single ad and the model's place in ADC's Sound Shaper family.
