Since its introduction in 1997 the Qbox has become one of
Whirlwind's most successful "Black Boxes" ever.
Now, we've added the features that have been most requested
by Qbox users over the years:
- A quieter headphone amplifier section for improved listening
quality.
- A handy MONITOR switch that 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 switch that disconnects the two XLRs from each other so
tone or internal mic can be sent out of one while you listen to
what's coming back on the other. Or connect the XLRs together
and "loop-through" or daisy-chain units.
- An improved, test-tone oscillator circuit that more closely
maintains the selected level into a wide range of load
impedances.
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 and cables 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.
