Superlux Pink Stick Measurement Microphone

Phantom-Powered Test Signal Generator for Live Sound

The Superlux Pink Stick is a precision audio test signal generator shaped like a long XLR plug. It runs entirely on 48 V phantom power from the mixing console, so no batteries are needed. The rotary switch sends pink noise, a 1 kHz sine tone, or a polarity-check pulse down the line, with a mute position between each mode. This compact tool is the right choice for sound technicians and stage patch staff who need a fast way to verify cabling, channel routing, and speaker polarity on a live rig.

What to Look for in a Pocket-Sized Tone Generator

Check the power source, output level, and build. The Pink Stick draws phantom power from the desk and its balanced mic-level output keeps long cable runs quiet. The metal-bodied XLR form factor survives daily transport.
