Provides good clean pink or white noise sound through your stereo system or computer speakers, which is a far better alternative than listening to white noise from a tinny little speaker found in sound conditioners.;Noise signals consist of true random impulses unlike the more common pseudo-random digital noise generators which create an algorithmic sequence of bits that eventually repeats. This device produces a TRUE white noise signal which is characterized by a +3dB increase in energy per octave. The pink noise signal contains equal energy per octave resulting in a smooth uniform sound that is pleasing to the ear (spectral analysis is shown in gallery).;Contains a special sophisticated filter that removes all frequencies beyond the range of human hearing (see picture gallery for spectrum analysis). This eliminates unnecessary loading that may otherwise be imposed on your audio system (unfiltered white noise can be hard on sound systems / tweeters).;Enclosure is made from rugged high-impact ABS plastic. Product is RoHS Compliant and is constructed with lead-free components and lead-free solder.;Purchase includes RCA cables (for hook-up to external audio equipment) AC adapter, and Owner's Manual. Comes with a 30 day money-back guarantee and a two year warranty (no need to fill out a warranty registration card). WE SERVICE WHAT WE SELL! If the unit needs repair even after the warranty has expired, just ship it back to us (repair costs are very reasonable).
