About This Tool
Managing entertainment lighting rigs, moving head fixtures, and LED dimmer packs requires precise allocation of DMX-512 universe channels across daisy-chained stage fixtures.
This interactive stage lighting interface calculates channel distribution across three parameters: Primary Dimension / Load (fixture starting channel), Secondary Parameter (universe fixture span), and Operating Factor (channel grouping multiplier).
The tool determines three operational lighting metrics: a fixture universe capacity quotient calculated as (Starting Channel × Fixture Span) / Grouping Multiplier, a geometric channel spacing factor calculated as √(Starting Channel × Fixture Span), and a universe channel allocation percentage calculated as (Starting Channel / (Starting Channel + Fixture Span)) × 100%.
For example, specifying a starting channel of 100, a fixture span of 20, and a grouping multiplier of 5 produces a Channel Capacity Quotient of 400.00 ((100 × 20) / 5), a Geometric Spacing Factor of 44.72 (√(100 × 20)), and a Universe Allocation Rating of 83.33% ((100 / 120) × 100).
All lighting channel arithmetic executes locally inside your web browser. No stage plots, fixture addresses, or lighting patch lists leave your computer.
How to Use
- 1
Input your fixture starting channel into the Primary Dimension / Load field (default 100).
- 2
Set your universe fixture span in the Secondary Parameter field (default 20).
- 3
Adjust your channel grouping multiplier in the Operating Factor box (default 5).
- 4
Review the computed fixture universe footprint, geometric spacing factor, and channel allocation percentage.
Frequently Asked Questions
What does the primary output represent for DMX configurations?
It calculates the channel capacity ratio derived from starting channel, fixture span, and grouping multiplier: (Channel × Span) / Grouping.
How does the tool calculate channel allocation efficiency?
The allocation percentage computes starting channel divided by the combined channel span: Channel / (Channel + Span) × 100%.
Is lighting rig data transmitted over the internet?
No. All calculations run strictly in local browser memory with zero network calls.
