On live stages, recording studios or home setups, XLR cables are one of the most essential mediums for connecting audio equipment. The quality of your cables directly affect whether the signal is transmitted properly. 
However, troubleshooting faulty cables often consume valuable time, and traditional multi-meters or bulky cable testers can make the process even more complicated. Due to this reason, we designed a tool which every musician and sound engineer should have - the XLR Cable Tester, a fast, compact and reliable solution for quick cable diagnostics.

Features

• Test XLR cable quickly and conveniently
• Durable metal housing with quick plug in and out design
• The sniffer unit can be used independently to quickly diagnose stage boxes or audio interfaces
• Humanization designed silicone sleeve for XLR Sniffer
