Preparing Equipment for Tech Week and Opening Night

Before tech week

Inventory every mic, pack, receiver, cable, battery and spare. Label packs and receivers with matching numbers.
Charge or buy batteries for every performance plus rehearsals. See Battery best practices.
Stock consumables: mic tape, remover wipes, sweat covers, belts or pouches, and windscreens.
Write the mic plot: who wears which mic in each scene, and every swap.
Test the projector with your actual content and the stage lights on.
Rentals: check the delivery date and complete the 24-hour inspection.

Coordinate frequencies with all show equipment on. See Setting up multiple wireless microphones.
Fit mics on every performer and set gain at full performance volume.
Walk the stage to check for dropout spots.
Check projector alignment and look for actor shadows.

Fresh or fully charged batteries in every pack, plus charged spares.
Each mic tested on the performer before the house opens ("mic check").
Spare mic and pack tested and ready backstage, with a plan for who swaps it in.
Projector on and warmed up; show computer on power with notifications and sleep turned off.
Mixer scenes/snapshots saved; channel labels match the mic plot.
Phone numbers handy: Stage Gear 718-874-2642; for rentals, Broadway Media 1-800-277-0343.

Pull batteries, let mics and packs dry, coil cables loosely and note anything that misbehaved. See Caring for body-worn microphones.
