Rational Acoustics has introduced a new version of its phantom powered pink noise generator.
Called the Noise Stick II, it offers a 25 dB increase in sensitivity from a device that is the same size as the original, and also has 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, outfitted with hand-matched transistors and 1-percent tolerance resistors.
A Linear Feedback Shift Register (LFSR) random number generator provides a pseudorandom signal with excellent statistical properties and without any obvious, audible repeats. The output of the random number generator drives a hand-tuned filter bank that delivers a pink spectrum that is nominally flat within +/- 0.5 dB from 30 Hz to 20 kHz on a 1/3-octave analyzer.
The housing for Noise Stick II is made from sturdy machined anodized 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 gravel surface and then run over by a car (the company does not recommend this treatment, however).
