If a microphone suddenly stops working on stage, these tools help you quickly locate the problem. Two versions of the XLR Generator are available and are very easy to use. Simply connect the Generator to the microphone cable and switch on the phantom power. The tool then helps identify the problem.

100 Hz Sine Wave Generator
In addition to generating a 100 Hz sine wave, this tool can also be used to check cables. The generator is powered by phantom power, so no battery is required.

Pink Noise Generator
In addition to generating pink noise, this tool can also be used to check cables. The generator is powered by phantom power, so no battery is required.

Phase Checker
Operates on 9–48 V phantom power and provides an output of approximately 100 mV peak-to-peak. The Phase Checker sends 6 pulses per second between pins 2 and 3. Its compact design makes it easy to use. XLR configuration: pin 1 = GND, pin 2 = +, pin 3 = −. LED ON = OK, LED Pin 2 = out, LED Pin 3 = fault.
