The SoundTool Sniffer and Senders are 'On the fly', highly reliable, testers with remote ends used in the field to quickly determine faulty NL4/Speakon cables at various stages and locations. They can also be used to quickly test phantom power on snakes.
Designed by Rat Sound to deal with the "real world" of pro audio, the SoundTools SSNL4 Sniffer cable tester is a amazingly simple and reliable tester with many unique features. Machined from durable aluminum tubing, the NL-4 Sniffer and Sender
combo utilizes battery power and 4 LED lights to troubleshoot cables, without bringing the ends together. Testing snake lines and cables with the ends located at a distance from each other is now simple and easy and you can do it without running extra cables just to test.
A durable anodized aluminum tube protects the all- analog testing units. There are no fragile moving parts or seams, making these some of the most indestructible testers on the market. Every Sniffer/Sender Unit comes with a sticker that can be attached to the sniffer end (or where ever is most convenient for you) that shows what the LED light combinations mean. Also available for XLR, DMX, and 1/4" TRS connections.
