This guide covers the full signal chain for live lighting and visual systems: Front of House (FOH) lighting rig, stage fixtures, control consoles, signal distribution, and power/data management. It’s written for real-world setups from small clubs to mid-size venues. No frameworks required—just copy/paste.

1) Front of House (FOH) Lighting System

Core Components

• Input sources: lighting cues, timecode, MIDI triggers, and show control software.
• Console: DMX or Art-Net desk handling patching, programming, playback, and effects.
• Signal distribution: DMX splitters, nodes, and switches for Art-Net/sACN networks.
• Power control: dimmer packs for conventional fixtures or power distro for LED and intelligent fixtures.
• Fixtures: washes, spots, beams, strobes, blinders, pixel bars, and audience effects.

Design & Coverage

• Stage layout first: define zones (front wash, mid beams, backlight, FX) and audience lighting.
• Beam angles: choose lenses or optics (e.g., 15°–60°) to cover stage evenly without spill onto walls or ceilings.
• Fixture height: balance throw distance and viewing angle; avoid glare in performer sightlines.
• Front wash: aim for even, shadow-free coverage using warm/cool color balance.
• Backlight and side fill: add depth and separation between performers and background visuals.

System Setup (Order of Operations)

1. Rig placement of trusses, bars, and mounts to achieve coverage and sightline goals.
2. Addressing and patching: assign DMX addresses logically by position or type.
3. Signal verification:
   • Use a DMX tester or console output to confirm data reach and universe mapping.
   • Check latency or flicker on networked protocols; terminate lines properly.
4. Fixture calibration:
   • Set pan/tilt home positions and dimmer curves.
   • Match color temperatures across fixture types (e.g., 3200K–5600K).
5. Safety check: verify clamps, safeties, and cable strain reliefs before power-up.

Intensity & Color Balance

• Target consistent 600–900 lux across performance areas for balanced camera and audience viewing.
• Use warm/cool pairs (e.g., 3200K front + 5600K backlight) for natural contrast.
• Maintain color consistency using fixture profiles or white balance calibration tools.

Typical DMX Universe Planning

• Universe 1: front and wash lighting.
• Universe 2: movers and FX (spots, beams, strobes).
• Universe 3: house lights, audience blinders, and video wall control.

Noise, Flicker & Interference Prevention

• Use shielded DMX cabling and proper termination at the end of each line.
• Separate power for lighting and audio; avoid shared dimmer circuits with sensitive gear.
• Maintain clean grounding; avoid star-ground loops between distro and fixtures.

FOH Lighting Check Checklist

• Run a fixture test chase to verify all heads, colors, and dimmers respond correctly.
• Walk the room; confirm even coverage, no glare, and proper focus.
• Confirm fade curves and timing match show cues.

2) Stage Lighting (Washes, Spots & FX)

Choosing Fixture Type

• Washes: broad, even coverage for faces and stage fill.
• Spots/Beams: accent performers or create dynamic aerial effects.
• FX lights: strobes, blinders, and pixel bars add energy during key moments.

Fixture Placement

• Front light: 30°–45° angle from audience perspective for flattering shadows.
• Side light: adds dimensionality; mount at performer shoulder height when possible.
• Backlight: separate talent from background; use strong color contrast for mood.
• Audience FX: ensure safe aiming and intensity limits to prevent glare.

Programming & Control

• Cue stacks for structured shows; busking pages for live control flexibility.
• Color palettes and beam presets streamline fast programming.
• Sound-to-light triggers via audio feed or internal mic for synced moments.

Safety & Power Distribution

• Use rated clamps and secondary safeties on all fixtures.
• Label and balance power circuits; monitor current draw per phase.
• DMX isolation and proper termination prevent flicker and erratic movement.

Show Workflow

1. Confirm patch & addressing before focus.
2. Focus and label zones (front, back, FX, audience).
3. Program base looks, chases, and blackout cues.
4. Rehearse transitions; timecode or MIDI sync if needed.

3) Lighting Consoles (DMX & Networked)

Console Fundamentals

• Patch all fixtures with consistent channel modes and profiles.
• Groups and palettes simplify color and position control.
• Faders handle intensity, color, and effects speed during live playback.
• Masters allow overall dimming or zone control.

Bus Architecture & Networking

• DMX universes via XLR or Art-Net/sACN over Ethernet.
• Submasters and playbacks for flexible live operation.
• Media server integration for synchronized video playback or projection mapping.

Digital Console Advantages

• Show files with cues, palettes, and macros saved per artist or event.
• Integrated RDM and pixel mapping tools.
• Timecode and automation for precise sync to music or visuals.
• Remote control apps for wireless focus and adjustments.

Analog/Dedicated Controllers

• Reliable for smaller rigs; assign faders to fixture groups manually.
• Document patching and scene sequences for repeatability.

Festival/Changeover Workflow

1. Advance patch lists; prepare generic show file.
2. Color-code fixtures and pages; clear labeling helps visiting LDs.
3. Line check DMX output and verify focus during first song.

4) Visual Systems (LED, Projection, Media Servers)

LED Walls

• Resolution & pitch: choose P3–P6 for close viewing; P8+ for distance.
• Processing: ensure compatible video scaler or media server output.
• Rigging: use load-rated frames; align panels for seamless joins.

Projection Mapping

• Short-throw projectors for tight spaces; keystone or warp using media server tools.
• Consider ambient light; increase output (lumens) to maintain contrast.

Media Servers

• Playback control: timeline-based or triggered via DMX/MIDI.
• Layer compositing for overlays, logos, and real-time visuals.
• Content sync with lighting cues for immersive shows.

Color & Brightness Calibration

• Match LED wall color temp to stage lighting (around 5600K).
• Set brightness balance to avoid blinding or washed-out visuals.
• Regularly calibrate panels and projectors to avoid hue drift.

5) Venue Lighting Environment & Acoustics Interaction

Ambient Light Management

• House lighting zones controllable via DMX for smooth transitions.
• Use warm tones (2700–3200K) for audience comfort; dim gradually for cues.
• Backlighting enhances stage depth; avoid spill onto FOH screens or consoles.

Stage-Visual Coordination

• Align visual themes with music tempo and mood.
• Use haze for beam definition; maintain safe visibility for performers.
• Balance light intensity with projection/LED brightness for harmony.

Noise & Power Management

• Fan noise from fixtures—keep away from microphones or record zones.
