M
MOLEFAY
8-lamp flood lantern used for washing large areas of stage with color, or as an audience "blinder" for a concert. Sometimes fitted with color crollers
for maximum flexibility. Consists of 8 PAR 36 ACL (AirCraft Landing) lamps.
MONITOR
- An onstage speaker which allows a performer to hear the output of the PA system, or other members of a band.
- A video display screen (not normally able to receive broadcast TV pictures) used with a CCTV system or a computer.
- Enables the sound to be heard by the performer.
MOON BOX
Lighting effect. A large shallow circular box with calico cloth on one face and low wattage lamps arranged on the back. Can be flown behind a gauze or thin cyclorama to give the effect of the moon rising.
MOVING LIGHT
- A common term for automated fixture.
- Remotely controllable "intelligent" lighting instrument. Each instrument is capable of a massive variety of effects which are operated "live" via a moving light control desk, or can be pre-programmed by a standard memory lighting desk. The instruments require a power supply and a data cable (normally carrying DMX512 signal from the control desk). There are broadly two types:
- Moving Head: A luminair is mounted on a moving yoke.
- Moving Mirror: A stationary luminair directs light onto a motorized mirror.
Both types have in common: A discharge (non-dimmable) light source. A dimming shutter.Motorized rotating color wheels. Some offer color mixing using graduated red, green and blue wheels or prisms. Profile versions have motorized gobo wheels with rotation. Strobing effects and adjustable iris. Some also have shutters. The term "intelligent" is used as the instrument has a processor chip and electronics built into it, not because it's able to interpret the designer's artistic intent! It can be incredibly frustrating trying to get moving lights to behave exactly as required in a dramatic situation. Musicals and live music performances are more forgiving. Moving Head lanterns are sometimes known as NODDING BUCKETS, Moving Mirrors are sometimes known as WIGGLIES or SCANNERS.
MOVING MIRROR AUTOMATED FIXTURE
A classification of automated fixtures which achieves beam motion by reflecting the beam off of a remotely controlled motorized mirror. The Cyberlight (TM) by High End Systems, and the Roboscan (TM) by Martin, are examples of moving mirror automated fixtures.
MOVING YOKE AUTOMATED FIXTURE
A classification of automated fixtures which achieves beam motion by remote motor controlled movement of the yoke and body of the fixture. The Vari-Lite series of automated fixtures (TM) Vari-Lite, are an example of moving yoke automated fixtures.
MR16
