1. adj. Horizontal. Usually,
parallel with the floor, provided that the floor is level. Perpendicular to
plumb.
2. Tool, Scenic. Shortened version of
spirit level.
3. A/V. Amount of energy in a signal. Related terms:

Mic Level,

4. Lighting. The percentage of
intensity of a
luminaire. Most consoles use the syntax [Channel] [@] {level in %, or FL or FF for 100%}. Some consoles have a key labeled [Level], user-definable to whatever percentage is desired. If an
LD usually brings a
channel to 75% initially, setting [Level] to 75% will save a couple of keystrokes.
