Product manual

Limit: Affected channels cannot get larger values than directly set with the Grand Master
slider. For example, Grand Master at 127 will result in all affected channel's maximum
values being limited at exactly 127.
Head
A head represents an individual light output device in a fixture. Usually, a single fixture contains
exactly one output, like the lens, the bulb, or a set of LEDs. There is, however, an increasing
amount of fixtures in the market that are treated as a single fixture, but they have multiple light
output devices, i.e. heads.
For example, you might have a RGB LED bar fixture that is packed into a single chassis, and as
such it appears as a single fixture with one DMX input and one DMX output, but that actually
comprises of four separate RGB LED "fixtures". These separate fixtures are treated in QLC+ as
heads; they share some common properties with their sibling heads, they can be controlled
individually, but they might also have a master intensity control that controls the light output of all
the heads together.
Each head belongs to a Fixture Mode because in one mode, a fixture might provide enough
channels to control each of its heads individually while in another mode, only a handful of
channels might be provided for controlling all heads simultaneously.
HTP (Highest Takes Precedence)
All channels that have been assigned to the Intensity group obey the very simple HTP rule: The
highest value (nearer 100%) that is currently set to the channel is the one that gets sent out to the
DMX universe. This is particularly useful for dimmer channels that namely control the light
intensity. Let's say you have two sliders that control the same intensity channel. First, you set
slider 1 to 50% and then slider 2 to 75%; as long as slider 2 is below 50%, nothing happens but
after crossing the 50% value set by slider 1, the light intensity increased all the way to 75%. If you
drag slider 2 again to 0%, the light intensity diminishes until it reaches the 50% set by slider 1
and stays there until slider 1 is dragged down. See also LTP.
Input plugins
Primary input methods for QLC+ are naturally the keyboard and mouse. Users can attach
keyboard keys to virtual console buttons and drag sliders and do pretty much everything with a
mouse. It is possible to attach additional input devices to one's computer to alleviate the rather
clumsy and slow user experience that is achieved with a regular mouse and a keyboard. Special
input plugins provide capabilities for getting external devices (mainly slider boards) to produce
input data to various QLC+ elements.
Input (line)
An input is a physical input line provided by some hardware which is accessed thru an input
plugin. It can be, for example, a MIDI IN connector in the user's computer (or peripheral) to which
users can connect MIDI-capable input devices like slider boards etc.
Input profiles
Input profiles can be thought of as fixtures' cousins; they contain information on specific devices
that produce input data. An input device can be, for example, a slider board like the Behringer
BCF-2000, Korg nanoKONTROL, an Enttec Playback Wing...
