Rational Acoustics LLC Noise Stick 2


MSRP: $89.00

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. It features 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. A green LED on the endcap provides visual confirmation that the unit is seeing phantom power and thus, operational.
