Radio Mic Plot
Plot radio mics by scene with cast, mic type, stage position and on/off cues.
Stage Plan & Blocking
Block every scene on a top-down ground plan: drag set pieces and cast, add crosses, spikes and notes.
JSA / Risk Builder
Drag-and-drop common event, AV and rigging hazards and build the risk matrix and controls alongside.
AV Quote Estimator
Event type, guests, hours and add-ons to an indicative range and an itemised gear list.
What AV Do I Need?
Five quick questions to a recommended sound, lighting and vision setup.
Marquee & Tent Size
Guests and seating style to a floor area and a suggested marquee size.
Dance Floor Size
Guests and the share dancing to the right floor area and panel count.
Staging Size & Decks
Who is on stage to a deck count and stage footprint.
Stage, sound & lighting plots
Map your rig to scale and export a clean plan.
Stage Plot Planner
Drag and drop a stage layout to scale, speakers, monitors, risers and power, then export a clean plan.
Lighting (LX) Plot
Plot your rig to scale with channel numbers, gel and an auto fixture schedule.
Sound Coverage Planner
Map SPL, coverage and interference across a speaker layout with delay alignment and a coverage report.
Subwoofer Array Designer
End-fire or cardioid, get the delay and polarity for each sub.
DMX Universe Planner
Add fixtures for total channels, universes and a start-address patch.
Run Sheet Builder
Add timed items, get start and end times, copy the run of show.
Audio calculators
The numbers behind a clean, even, loud-enough mix.
Mix Map
See where every voice and instrument sits in the frequency spectrum, with live masking analysis between sources.
Pro Audio Calculators
Ten calculators in one, SPL and throw, amp matching, sub delay, power, cable drop, RT60, RF and more.
PA SPL & Throw
How loud a box gets at a distance, and whether you have headroom over target.
Amp ↔ Speaker Matching
Total load impedance and the amp power to drive your cabs safely.
Subwoofer Array Delay
Delay and polarity for end-fire and cardioid sub arrays.
Speaker Delay / Align
Time-align fills, delay towers and subs, temperature-corrected.
RT60 Room Acoustics
How reverberant a room is from its size and surfaces (Sabine).
RF Coordination (AU)
A clean, intermod-aware set of frequencies for radio mics and IEMs.
Gain & Headroom
Line up your nominal level with the converter clip point.
dB / SPL Toolkit
Voltage to dBu/dBV, combine SPL sources, level over distance.
Room to PA Recommender
Guests, use and setting to a recommended PA size and power.
Noise Limit & dB Exposure
Level at a distance vs a council limit, plus safe exposure time.
dB / Watts Converter
Power ratios in dB, SPL change and metres to feet.
Light & vision
Get the picture right, from lux on stage to pixel pitch.
Lighting Lux & Coverage
Lux on stage from lumens and beam, or fixtures for a target level.
Projector & Screen Size
Throw distance to screen size and back, width, height and diagonal for any throw ratio.
LED Wall Pixel Pitch
Resolution, pixel count and minimum viewing distance.
Aspect Ratio & Resolution
Matching width or height for any aspect ratio.
Power & rigging
Size the supply, balance the phases, check the loads.
3-Phase Load Balancer
Spread loads across phases, amps per leg and imbalance.
Power & Generator
Current per phase and the generator kVA your rig needs.
Generator Runtime & Fuel
Fuel burn, runtime and fuel needed from load and tank size.
Power Draw Audit
List gear for total watts, amps and circuits needed.
Cable Voltage Drop
Whether a power run holds up over distance, and when to step up gauge.
Cable Run & BOM
Runs by type and length to a tidy bill of materials.
Truss Span & Load
Total hung weight and centre of gravity, a rigging planning aid.
No tools match that search.
