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 1/4" jack for line-in or a 2k Ohm (telephone) earpiece out, plus voltage presence LEDs for confirming phantom or intercom power. A handy clip attaches the Qbox to your belt or equipment rack. For an instant hands-free intercom, simply plug in headphones and hook up one Qbox on each end of a line. Use it to monitor a standard 3-wire intercom feed or talkback from the main audio console. The Qbox can quick-check dynamic mics without firing up the entire system. It provides a handy mic or line-level tone for activating a signal path or identifying a specific cable in a pile of cable ends. Powered by a single
