About

Unrival

Features
Read full description

UNRIVAL is the professional iPhone app for preparing, patching, and maintaining entertainment lighting fixtures. Adjust DMX addresses, modes, personalities, network settings, IDs, and other parameters directly from your phone — no fixture display, no buttons, and in supported cases, no power applied. In practice, that means a prep tech can configure fixtures on the shelf, on the truss before flying, or sitting on top of a roadcase — and turn over a full rig before the first power cable is ever pulled. (NFC requires the phone to be close to the fixture's tag; it will not read through a closed roadcase.) KEY FEATURES • Easy patch/edit of any setting — direct access to fixture settings without the fixture's display or buttons. Change DMX address, mode, personality, network settings, IDs, and other parameters from the app. • Templates & Auto Prep — save known-good fixture configurations and apply them consistently across many fixtures. Auto Prep automatically applies saved templates as you work through a batch. • Rapid Patching from imported patch lists — bring in show data from ChamSys CSV, ChamSys QR Code, and MVR. For non-Chauvet NFC-enabled fixtures, the imported list also works as an easy-to-use manual patching checklist. • Operate and prepare fixtures while powered OFF — read fixture identity, review configuration, and prepare or apply supported settings with no power applied. A unique advantage over display-only or powered-only setup methods. Useful on the prep shelf, on the truss before flying, on top of a roadcase, and during pre-rig. • Firmware Update over Bluetooth — wireless firmware updates from your iPhone over BLE. No specialist cables or service tools required. ALSO INCLUDES • Fixture diagnostics — usage data and error history for faster troubleshooting and clearer maintenance records. • Scan History — a record of previous fixture interactions for traceability and less duplicated work. • Quick Tools — one-tap "Auto Test" and "Reset Defaults" for routine procedures. • MVR 2D & 3D visualizer — visual representation of fixtures inside a project or rig layout from MVR data; aids fixture identification on complex rigs. • Trip Management — organize fixtures and setup activity around specific jobs, projects, or deployments. Supports rental, touring, and install workflows. BUILT FOR Rental prep floors. Touring lighting crews. Install integrators. Service and maintenance teams. Master electricians, theatre, broadcast, houses of worship, film, and TV. USE IT FOR Pre-show prep • Patch turnover • Rental return inspection • Fault-finding in the field • Firmware rollouts • Inventory and identity tagging • Manufacturing QC • System commissioning GET STARTED Install UNRIVAL, open a Trip or load a patch list, and start working through your fixtures — powered or not.
