Truss, Vari-Light, Wedge or Monitor


A framework of alloy bars and triangular cross-bracing (usually of scaffolding diameter) providing a rigid structure, particularly useful for hanging lights where no permanent facility is available. Very often box-shaped in cross section, so known as BOX TRUSS. This type of truss is useful for touring as lanterns / speakers etc can be hung inside the truss which protects them when loading and takes up less space in the truck.


Trade name for a range of "intelligent" moving lights and control equipment. Identified by VL numbers. The VL1 model was introduced in 1980 for a Genesis tour by Showco, USA.


Due to concert noise levels it is sometimes impossibe for a musician to hear his own instrument. These monitors allow them to hear their own instrument and what they are playing.
