Whirlwind's Q-BOX is one of Whirlwind's most successful "Black Boxes" ever. It's the all-in-one audio line terster that's ideal for applications such as live sound, maintenance, installation work, or anywhere audio runs down a cable. The Q-BOX comes with a microphone, a speaker, a test tone generator, outputs for standard headphones, a 1/4" jack for line-in or 2k Ohm (telephone) earpiece out, and a handy clip to attach 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 Q-BOX can quickly check dynamic mics and cables without having to fire up the whole 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 Q-BOX is light yet able to withstand the wear and tear of fieldwork.
