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 aluminium 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!
