General Information

Designed by Rat Sound to deal with the "real world" of pro audio, the SoundTools XLR Sniffer/Sender is the perfect tool for live environments. Test snake lines and cables when the ends are at a distance and avoid running extra cables just to test. Utilizing phantom power the Sniffer end can quickly test snake lines in minutes. The aluminum barrels eliminates the problem many testers face with solder joints failures and the unit will never rust. 3 simple LED’s will instantly diagnosis your cable as it tests for every possible shot, open, or cross wire in XLR cables. If the LED’s read all green you cable will work!


The XLR Sniffer tests the continuity of XLR cables. By attaching it to the female end of a cable with phantom power or the sender unit on the opposite end, it will instantly diagnose the status of XLR cables by using 3 LED lights.

The Sender unit simulates phantom power. By twisting the cap clockwise the unit will switch on. Once the sniffer is on the opposite end a single LED indicator on the Sender cap will light up.

Data Sheets

XLR Sniffer LED Color Code


The LED's on my XLR Sniffer/Sender are showing all red when plugged directly into each other. Is it broken?

Typically this occurs when the batteries are put in backwards. Reversing its position will return it to all green. This function is for our colorblind users who commonly have trouble seeing the green LED's. All red would mean the cable is functioning properly.

Some of my XLR Sniffer LED's are orange. What does that mean?

If you see any orange LED's that means your unit has a orange led swap with the traditional red. Below is a link to an updated color code chart for the orange LED's. If you'd like to exchange your unit for a standard red LED sniffer please send an email to support@soundtools.com.
