Terminal Strip (a.k.a. barrier strip)

A series of connections, usually screw terminals, arranged in a line to permanently connect multiple audio lines to such devices as recording equipment, mixers, or outboard gear. Back in the ’70’s much of the high end recording equipment only had terminal strips on the back for connection. Since this equipment was primarily used in pseudo-permanent professional facilities it was considered the most cost effective and reliable way of connecting things. Nowadays most pro equipment is fitted with some combination of 1/4″ (TS or TRS), XLR (see WFTD archive XLR) and possibly still terminal strip connections. Equipment sold primarily for use in permanent installations (contracting) such as stadium or theater sound is still frequently equipped with terminal strips only.
