RFRanger

Wireless mic monitoring for Mac and Windows

Your wireless.
Under control.

See battery, RF and audio for every wireless mic at a glance, and give your performers a screen that shows which mic is theirs and whether it's ready. Free, and runs on the computer you already have at front of house.

Latest release and notes

RF Ranger's engineer view: a grid of mic channels, each with its readiness, battery, RF and audio meters, and a five-second audio waveform on some

About

RF Ranger is for church and live-production teams who want to know, before the service starts, that every mic is charged, switched on and healthy. It finds your Shure receivers on the network by itself and opens in your browser, so any laptop, iPad or TV on the same network can show it.

Engineer view with ready, battery-low, on-charger and charging channels

Every channel at a glance

Green is ready, orange is off or on the charger, red is a low battery or a fault. Show presets put just the mics you need for worship, the message or announcements on screen, and give each one a nickname for the day: RF-4 is "Josh" this week.

A channel's detail panel with a five-second audio waveform and an RF strip underneath

What just happened?

A five-second audio waveform with the RF signal underneath. If audio drops out with the RF, it's a wireless problem. If audio spikes while RF holds steady, someone bumped the mic.

Pickup view: large cards with each performer's name, their mic, and whether it's ready

A pickup screen for the team

Put it on a TV by the RF table. Performers find their name, see which mic or pack is theirs, and whether it's ready. No more "which one's mine?" five minutes before downbeat.
