R
REFLECTED GLARE
Glare resulting from bright reflections from polished or glossy surfaces in the field of view. Reflected glare usually is associated with reflections from within a visual task or areas in close proximity to the region being viewed.
REFRACTOR
A device that transmits and redirects the luminous flux from a source. Refractors for outdoor luminairs are typically made from acrylic, polycarbonate, or glass, and when well-designed, help control direct glare.
RELAY
A device that performs the actual on or off switching of an electrical load due to small changes in current or voltages.
REMAINDER DIM
A command used on Strand Lighting memory control desks which is comparable to the SOLO function on other desks. For example, entering CH 5 REM.DIM will put channel 5 at full and will put everything else at zero.
REMOTE CONTROL
Used to activate a unit's features from a distance.
RE-RIG
To change the lighting rig after the last performance of one show to the positions for the next show.
RESISTANCE DIMMER
A now obsolete method of dimming which decreases the current available to the load by introducing a variable resistance between supply and load. The excess current is converted into heat. Based around a rheostat.
RESISTIVE LOADS
Restive loads are lighting units that have no capacitive or inductive components (No transformers, Starters or Ballasts) All mains filament lamps are resistive loads e.g. Par56 .
RESOLUTION
- The point during a drama when the plotline reaches a conclusion, and conflict is resolved.
- A measure of the quality of a video display.
- The quality of a sound sample is measured by the sample rate (e.g. 44.1kHz is CD quality sample rate) and the resolution (either 8 bit or 16 bit normally).
RESTORE
A cue to resume or return to any previous state, setting or function. (e.g. "at the end of the dance number we restore to a warm general over").
