Euroblock is a type of terminal block connector (see WFTD Terminal Strip) frequently seen on products used in the audio installation market. They feature an interlocking male and female style connector that often carry the same signals as a balanced XLR or TRS connector used most often in pro audio devices. The Euroblock style connector requires no soldering to make cable interconnections. Instead, the wire is stripped, inserted into slots in the connector, and then each wire is tightened into place with the aid of a standard screwdriver. They come in several sizes (number of terminals), as well as a few different shapes.
