What is patching lighting?

What is patching? Patching describes the act of connecting different parts of the lighting or sound system together. For example, some stage lighting installations have dimmers which are wall-mounted above a row of plugs, which can be used to connect any plug into any dimmer.

Patching. Hard Patch: Hard patching refers to making a physical electrical connection. It nearly always refers to the connection between a dimmer and a circuit. Soft Patch: Soft patching occurs within the software of computer lighting boards. It nearly always refers to the correlation between a channel and a dimmer.

Beside above, what is a submaster in lighting? Submasters, are faders similar to the grand master fader that most every console has in some form. Submasters control the output of a group of lights that is recorded to that fader. Unlike the grand master, or GM, they are typically not inhibitive but additive.

Keeping this in consideration, what is a dimmer in stage lighting?

Stage Lighting dimmers are used to increase or decrease voltage to a dimmable lighting fixture in order to adjust its intensity. Typically used with incandescent halogen or specific kinds of fluorescent fixtures, dimmers give us the flexibility to set the mood and/or focus attention on a specific section of the stage.

What is a light plot in Theatre?

A light plot, lighting plot or just plot is a document like an architectural blueprint used specifically by theatrical lighting designers to illustrate and communicate the lighting design to the director, other designers and finally the Master Electrician and electrics crew.

What is DMX lighting?

Definition of DMX DMX512 (Digital Multiplex) is a standard for digital communication networks that are commonly used to control stage lighting and effects. It was originally intended as a standardized method for controlling light dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols.

How do I connect to DMX?

Connect a DMX cable from the DMX controller to the DMX IN of the first fixture, and a DMX cable from the DMX OUT of the first light to the DMX IN of the second. Put both fixtures into DMX channel mode (for this example, set it to 4-channel mode), and then set both fixtures to Channel 1.

How do you make a magic sheet light?

To create a magic sheet: Select Spotlight > Reports > Generate Paperwork, and then select Magic Sheets in the Generate Paperwork dialog box. Click the Setup button next to Magic Sheets. Click OK to close the Magic Sheet Setup dialog box and return to the Generate Paperwork dialog box.

How does a DMX dimmer work?

Dimmers are devices connected to a light fixture and used to lower the brightness of light. By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output. Modern professional dimmers are generally controlled by a digital control system like DMX or DALI.

What is a channel in Theatre?

Channel: A control path that allows the console to vary the output level of one or more dimmers or other devices. The channel can be physical (controlled by a button, switch or slider) or virtual, (controlled by a numeric keypad).

How does AC dimmer work?

A modern dimmer switch “chops up” the sine wave. It automatically shuts the light bulb circuit off every time the current reverses direction — that is, whenever there is zero voltage running through the circuit. This happens twice per cycle, or 120 times a second.

How many lights can you daisy chain DMX?

32 Fixture Rule – DMX only allows you to connect up to 32 fixtures in a single daisy chain for signal strength. Sometimes, depending on the fixtures and cable length, this number is less (or more). Realistically most people recommend only setting up 16 – 20 fixtures or devices in a Daisy Chain.

How long can you run DMX cable?

The DMX specification states the maximum length is 3,281’—but think about it. We are working in the real world; every connection can degrade the signal. A good working practice is to limit your cable run to 1,000′.

Can you connect two DMX cables together?

Technically speaking DMX can go up to 5000′, however most systems are designed to stay under 1500′. The “parallel” that is being discussed isn’t the right terminology. Inside a fixture or a dimmer the two DMX connectors are tied together, this creates a Y.

What is the difference between DMX and XLR?

XLR and DMX cables have a bit of overlap and it can be difficult to keep the two separate. The short answer is that XLR is used for audio while DMX is used for lighting. Both cables use the same kind of connectors and look the same on the outside, there are differences on the inside.
