Rational Noise Stick II – Phantom Powered Pink Noise Generator
The Rational Noise Stick II™ is the latest version of our phantom powered pink noise generator. The Noise Stick II is a study in simplicity, precision and ruggedness. Its mission is to do one thing really well and do it faithfully for years to come. The Noise Stick requires no batteries and no configuration. It doesn't even have a power switch. Plug it into a phantom-powered microphone input and it generates pink noise — very nice, well-behaved pink noise. Unplug it and it stops.
This updated version of the Noise Stick provides a higher output level than the previous version and includes a swanky new blue LED on the endcap that provides visual confirmation that the unit is seeing phantom power and thus, operational
The Noise Stick II is hand built in the USA exclusively for Rational Acoustics, sparing no detail for quality and reliability. It features such niceties as hand matched transistors, 1% tolerance resistors and a Linear Feedback Shift Register (LFSR) random number generator that provides a pseudorandom signal with excellent statistical properties and without any obvious, audible repeats. The output of the Noise Stick's random number generator drives a hand tuned filter bank that delivers a pink spectrum that is nominally flat within +/- 0.5 dB from 30Hz to 20kHz on a 1/3-octave analyzer.
We didn't skimp on the outside either. The sleek, compact design is unobtrusive and fits easily into mic cases and gear bags. The housing for the Noise Stick is made from sturdy machined anondized aluminum to protect the electronics from shock and increase its crush strength. Prototype test units were found to work just fine after being dropped from two stories onto a concrete surface and run over by a car, although we wouldn't recommend doing this to yours (on purpose). And a new, blue LED on the endcap provides visual confirmation that the unit is seeing phantom power and thus, operational.
