AMS DMX 15-80

The AMS DMX 15-80 was a rack-mounted digital delay/harmonizer, and the first delay produced by Advanced Music Systems, released in 1978. It had a mono input and stereo output. Its successor was the AMS DMX 15-80S, which had a stereo input and output.

Peter Gabriel first came across AMS equipment at The Townhouse, where he recorded Peter Gabriel 3 (a.k.a. Melt). The studio housed a DMX 15-80 delay line, which was used extensively on the album. Hugh Padgham also liked working with the DMX 15-80, preferring the regeneration filter.

Peter Gabriel later got himself a DMX 15-80, which he used to record Peter Gabriel 4 (a.k.a. Security) and So albums, alongside a DMX 15-80S. And he also used it for the So tour.
