REK-0-KUT DEHISSER DEMONSTRATION CD

 

The first cut is always the recording played normally with no noise reduction. For disc records, only the playback compensation was adjusted with the REK-O-KUT RE-EQUALIZER II for most accurate play. The second cut is the recording as processed thru the REK-O-KUT DEHISSER. The third cut is the recording as processed with a CEDAR Duo Auto Dehiss processor.

Please be aware of a particular psychoacoustic effect. When listening to recordings with high frequency noise, we also perceive more highs than are actually present. We tend to associate the two. When the noise is removed, we perceive that the highs are also removed.
