Whirlwind Qbox Mic/Line Tester

Generate into or monitor from your analog sound system at ANY point with the Whirlwind Qbox Mic/Line Tester.

The Qbox is the all-in-one audio line tester ideal for applications such as live sound, maintenance, installation work - anywhere audio runs down a cable. The Qbox includes a microphone, a speaker, a test tone generator, outputs for standard headphones, a ¼" jack for line-in or a 2k Ohm (telephone) earpiece out. A handy clip attaches the Qbox to your belt or equipment rack.

Simply generate into or listen to audio at any point in your system from the mics to the power amps to quickly confirm which sections are working and which ones aren't. The Qbox can quick-check dynamic mics and cables without firing up the entire system. Use the built in mic or tone generator at three different levels for activating a signal path or identifying a specific cable in a pile of cable ends. Powered by a single standard 9V alkaline battery and housed in rugged ABS, the Qbox is light yet able to withstand the wear and tear of fieldwork.
