The Valley People KEPEX II is a modular programme expander and noise gate combining Valley TA-101 VCA technology with continuously variable expansion, adjustable attack and release characteristics, and external keying facilities. Designed for the Valley 800 Series powered rack system, it provided professional recording engineers with a flexible means of controlling microphone leakage, reducing unwanted noise and manipulating the dynamic envelopes of recorded signals. Its extensive control facilities and ability to operate as either a conventional noise gate or a creatively keyed expander made it a versatile studio dynamics processor.

The Valley People GAIN BRAIN II, was a professional analogue limiter, compressor and ducker that introduced a new approach to dynamics processing. Incorporating Valley People’s proprietary Linear Integration Detection, Log Domain Processing, Peak Reversion Detector Correction and EGC 101 VCA, it was designed to provide precise control over audio dynamics while preserving the natural character of music and speech.
