Pink Noise Generator KitThe Velleman K4301 Pink Noise Generator kit is a powerful DIY tool to use along with a spectrum analyzer and a microphone to analyze the acoustic properties of your media room. Use a microphone with as linear of a frequency characteristic as possible (from 20Hz to 20kHz). If you have an equalizer, then the kit is even more useful as this allows you to not only see your systems performance, but you can also correct it. The circuitry is easy to modify to produce "white noise". Specifications Random digital noise 33 bit shift register Clock frequency: adjustable between 30 and 100kHz Pink noise filter: 3dB / octave (20Hz to 20kHz) Output voltage: 150mVrms Output impedance: 1Kohm Power supply: 9 - 12V AC or 12 - 15V DC / 5mA (not included) PCB dimensions: 2.8 x 1.7"
