Preset Boards - Preset boards are the most basic lighting consoles - and also the most prevalent in smaller installations. They consist of two identical fader banks, called 'scenes.' The faders (control slides) on th. Used Wholehog III. ese scenes can be manually adjusted. Each scene has the same number of channels which control the same dimmers, but only one is live at a time, so the console operator can build a. Used Wholehog III. scene, then fade to it. These scenes are often referred to as A-scenes and B-scenes, and a cross-fader is used to fade between the A and B scene.
Generally, a preset board operator has a cue sheet for each s...

Scoop Light - Scoop lights or Scoops are circular fixtures that do not have any lenses. They have a reflector at the back of the fixture that directs the light out of the fixture. Since they do not have any sort o. Used Wholehog III. f lens system they are cheaper than other fixtures. However, the downside of this makes it so that you can not focus the light at all (even PAR's allow for more control than scoop. Used Wholehog III. s).
Stepper Motor - A stepper motor is a type of electric motor that is used when something has to be positioned very precisely or rotated by an exact angle.
In a stepper motor, an internal rotor containing. Used Wholehog III. permanent magnets is controlled by a set of stationary electromagnets that are switched electronically. Hence, it is a cross between a DC electric motor and a solenoid. Stepper m. Used Wholehog III. otors do not use brushes and commutators.
Stepper motors have a fixed number of magnetic poles that determine the number of steps per revolution. Most common stepper motors have 200 full steps/revolution, mea
