Pick up the ultimate audio testing package and SAVE! Whirlwind's QBox and Cab Driver have become indispensable to sound engineers across the world, these guys never leave home without them!
The CAB DRIVER is a test device for checking the operation of the speaker components within enclosures. A pink noise signal source is sent through pushbutton selectors to an assortment of speaker connectors, including Speakon NL8 and NL4, 1/4" TS and banana jacks.
The pink noise level can be adjusted to appropriate levels for subwoofers, midrange cones and compression drivers and tweeters. There is also an XLR line output for feeding the pink noise to self-powered speaker units.
A DC OHMS TEST button applies 5 VDC to the output terminals selected with the pushbuttons for observing cone movement to identify speaker and cabling polarity errors. This also performs a DC Ohms test where three LEDs indicate approximate ranges of 4, 8, or 16 Ohms. This helps identify blown drivers in cabinets where the cones cannot be readily observed or in cabinets with multiple drivers in series parallel configurations.
The CAB DRIVER is powered by 4 AA batteries or can be powered by an external 6 VDC power supply (not included).
The Whirlwind QBOX has earned legendary status amongst sound engineers all over the World, and unsurprisingly so. The Whirlwind QBOX is the ultimate 'all-in-one' test solution for live stage audio, broadcast and perfect for maintenance and installations, 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. 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 bult 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.
For an instant hands-free intercom, just plug in headphones and hook up one Qbox on each end of a line and use the built-in microphone.
Use it to monitor a standard 3-wire intercom feed - LEDs confirm the presence of intercom or phantom power.
Use it as a squawk box to the stage from the main audio console during set-up. Works in a pinch as a handy, portable, powered monitor too.
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.
A handy MONITOR switch allows the user to listen to a balanced signal or to two separate unbalanced signals on pin 2 or 3 (referenced to pin 1), such as a two-channel intercom.
A SPLIT switch disconnects the two XLRs from each other so tone or internal mic can be sent out of one XLR while you listen to what's coming back on the other. Or connect the XLRs together and "loop-through" or daisy-chain units.
