Creating dramatic entrances with smoke cues

Sources for technical characteristics include manufacturer specifications and industry references such as ESTA and OSHA guidelines (see references at the end).

Designing the cue: timing, choreography and the smoke machine

A dramatic entrance is choreography between performer, lighting, sound and the smoke machine. Start by mapping the exact moment the smoke should start, peak, and dissipate relative to the music or light hit. Many designers use a pre-programmed timeline or DMX cue: for example, begin smoke 1.5–2 seconds before the vocalist steps into the spotlight so the visual halo is present at the reveal. For a punchy effect, a 0.5–1 second machine burst synced with a cymbal or light strobe can have strong impact. Test and rehearse: the same cue behaves differently when the audience fills the venue and HVAC changes airflow.

Practical cue checklist (smoke machine focused)

• Decide whether the smoke will lead the entrance or follow it.
• Set machine output level to match sightlines and stage depth.
• Program pre-warm or pre-charge if using heated fog machines to avoid delays.
• Assign a backup cue or operator to adapt to live conditions (e.g., stronger HVAC).
• Document cue timing in the show script and communicate with lighting and sound.

Control systems: DMX, wireless triggers and automation (smoke machine)

Modern smoke machines typically support DMX control, enabling precise cueing and integration into lighting consoles. Wireless solutions and remote timers are useful for smaller crews or mobile acts. For entrances requiring split-second timing, using the lighting console as master and assigning the fog machine to the same cue stack reduces latency. When using multiple devices, consider a central show controller to synchronize smoke machine bursts with lights, CO₂ jets, and audio triggers.

Safety and ventilation: protecting audience and performers

Smoke effects can trigger alarms, irritate sensitive individuals, or create slip hazards. Follow these safety practices:

• Always notify venue management and fire marshals in advance and secure written approvals.
• Check local fire codes and life-safety requirements; many venues require documentation for theatrical effects.
• Use approved fluids and manufacturer-recommended concentrations to reduce respiratory irritation.
• Test detector sensitivity: some smoke detectors can be temporarily masked by authorized personnel or adjusted according to venue rules—but only with official consent and proper procedures.
• Plan ventilation post-cue so smoke clears between scenes or before audience egress points are used.
• Provide performer briefings on slip and visibility risks when moving through dense fog.

Adhering to these measures protects attendees and maintains compliance with venue policies.

Maintenance, setup, and reliable operation of your smoke machine

Reliability matters. A failed smoke machine ruins a key moment. Maintain machines by following manufacturer schedules: clean fluid lines, replace wicks or heaters as recommended, and only use approved fluids. Keep spare fluid, fuses, remotes, and basic tools on hand. For touring setups, protect machines in flight cases and document each unit's service history. Also perform a full systems check during load-in, and run the machine at the output levels you will use during the show to verify performance and to calculate how much fluid you'll consume for the event.

Common troubleshooting tips

• No output: check fluid level, pump priming, and power supply; confirm no clogged nozzle.
• Weak output: decrease viscosity by switching to recommended fluid, warm up machine fully, or check pump pressure.
• Delayed output: ensure heater is up to temperature; pre-warm when using high-output machines.
• Erratic bursts: inspect control cable/DMX, verify software cues, and check for intermittent power.

Integrating smoke machine effects with lighting and sound

Smoke amplifies light by scattering beams—this is why lighting designers love it. Use warm backlighting and side beams for silhouettes, and pin spots to draw attention through haze. Sound design can build tension so a smoke cue lands on a musical resolution or a beat drop. Coordination between lighting and smoke operators during tech rehearsals ensures that intensity levels complement the intended visual instead of washing out the stage or obscuring the performer.

Case examples: practical entrance concepts

1) Concert opener: Use a high-output fog machine to create a theatrical cloud that conceals the band. Cue a CO₂ jet on the beat for dramatic impact as the lead singer hits the first note. 2) Theater reveal: Employ a low-lying dry ice effect to make a character appear to rise from the ground—pair with dim blue sidelights. 3) Corporate product launch: Opt for haze with subtle fog bursts to accent logos lit by gobos and create a High Quality reveal without setting off alarms.
