Free-field estimate. Real rooms add reflections and gain.

Advanced planning suite · cabinet aware

LED Wall Configurator

Turn an LED cabinet profile and deployment goal into buildable geometry, native raster, content-fit guidance, NovaStar port estimates, viewing distance, and separated typical and maximum power plans.

Product / Cabinet Profile

When both raster fields are entered, they are authoritative and pitch is a validation check. Leave both blank to derive cabinet pixels from dimensions ÷ pitch.

Layout

Cabinet layout uses the entered whole-cabinet array directly.

Audience CheckReview
  • Enter a cabinet profile to review planning assumptions.

Planning estimates only: Verify final cabinet, receiver-card, processor, signal, and power specifications against the actual product documentation. Confirm electrical distribution with the venue and a qualified person; the calculator does not establish code compliance or a verified safe load.
