Pro Audio Tool!

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 standard 9V alkaline battery and housed in rugged ABS, the Qbox is light yet able to withstand the wear and tear of fieldwork.

The SOURCE section of the Qbox lets you send a tone or the signal from the built-in condenser mic at mic or line levels.

The SPEAKER volume control lets you confirm incoming signals at mic or line level.

Should be one in every tech toolbox

This fits into the "why didn't I think of that?" category. I worked at a company that had two of them and after working a freelance job without a QBox that had signal issues, I immediately bought one for myself. Listen to signal at almost any point in signal flow of any system, while sending signal at the same time. Plus you can use it as a listen box or down and dirty communication! Every tech should have one in their toolbox. Great build quality, size and overall design.

A real time saver that is worth the price

We have been very pleased with the ease of use and the many features which has paid for itself by allowing us to quickly pinpoint intermittent connections and defective mikes. I would highly recommend this tool for anyone tasked with maintaining systems quickly with a minimum of manpower.

Great Product

Perfect test solution for broadcast audio and stage audio situations. Monitoring on both comm channels of an RTS line is great and power indication LEDs let you know if the line is powered. Only complaint is the mic being in the top of the box is prone to getting rain in it, and I wish the body was a tougher plastic or made of metal.
