WHIRLWIND Qbox (VER 2) : Mic / Line Tester
The Whirlwind 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 Whirlwind 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
Whirlwind 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 Whirlwind 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 Whirlwind 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.

(VER 2) ADDED FEATURES: |
- 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 unconnects 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.
