Whirlwind QBOX - Audio Line Tester/Cable Tester/Test Tone Generator

The Whirlwind Qbox is an in-line, 9V battery-operated beltpack audio testing utility device, designed for live sound, studio maintenance, and installation applications.

The Whirlwind Qbox includes a microphone, a speaker, a test tone generator, outputs for standard headphones, a TT bantam jack, a 1/4" jack for a line-in or a 2k Ohm(telephone) earpiece out, along with voltage presence LEDs for confirming phantom or intercom power.

The Whirlwind Qbox is suitable for multiple purposes including hands-free intercom use when connected to another Qbox. It provides a mic- or line-level tone for activating a signal path, or identifying a specific cable in a pile of cable ends, and can also be used to monitor a standard 3-wire intercom feed of talkback from the main audio console.
