The following selections demonstrate the reduction obtained with our calibration signals. The clicks are from real LP records and are computer multiplied. Each SURFACE NOISE REDUCER is calibrated to produce minimum noise with the first of these signals. As before, the three following tracks demonstrate the noise reduction produced by the three devices.
Tracks 37 to 40: 1 kHz tone with clicks
Tracks 41 tp 44: Clicks by themselves
