A monoscope was a special form of cathode ray tube that was used to generate, rather than display, a video signal. Each tube was only capable of generating a single video signal, hence the name. This kind of test card generation system was technologically obsolete by the 1980s, but served many private and state broadcasters faithfully since its early use in the 1950s.

Essentially similar in construction to an ordinary CRT, the monoscope contained a formed metal target in place of the phosphor coating at its "screen" end and as the electron beam scanned the target, a varying electrical signal was produced.

This signal reproduced an accurate image of the target and so could be used to produce test patterns and the like. For example, the classic Indian Head test card shown on the right was often produced using a monoscope.

Monoscope "cameras" were widely used to produce test cards, Station Logos, special signals for test purposes and of course announcements, like "normal service will be resumed....". They had many advantages over the use of a more expensive live camera, they were always ready, and were never misframed or out of focus.

Dub FX (real name Benjamin Stanford) is a worldwide street performer and studio recording artist from St Kilda, Melbourne, Australia. After playing and singing in a band called Twitch, he set out solo when he moved to Europe. His trademark is creating rich live music using only his own performance aided by Live looping and effect pedals combined with his voice. He creates intricate hip hop, reggae and drum and bass rhythms.

Stanford travels and performs with his fiancée, Flower Fairy. Dub FX first met her in Manchester, and she joined him in his travels around the globe to busk for the public. Flower Fairy can usually be seen selling CDs during Dub FX's performances and also performs a few songs alongside Stanford. She is featured singing in the songs on Everythinks A Ripple, Wandering Love, and Time Will Tell.

Two songs from Everythinks A Ripple, Flow and Wandering Love, feature a street saxophonist named Mr Woodnote, who also uses similar looping techniques as Dub FX using a saxophone.

In 2010 Dub FX collaborated with Melbourne based producer Sirius and released the album titled: Dub FX and Sirius -A crossworlds. A Crossworlds could be defined as dubstep because of the heavy emphasis on sub frequencies and the tempo's used ranging from 138 - 145Bpm. Dub FX does not beatbox on this album. Any information on how Dub Fx and Sirius came to collaborate or meet is unknown.
