Quality LP record clamp from Tonar made from machined alloy with a soft grip top. Any vibrations in the record during playback will be picked by the cartridge and will be reproduced by the amplifier and speakers causing muddy sound, distortion and reduce detail. In order to avoid record vibrations you must make certain that the contact between the record and the platter is perfect. The tonar record clamp presses the record flat against the platter, which also helps to lessen the impact of any record warps present. Simply place the record on the turntable and then put the clamp on the spindle, press down then turn the knob to tighten. The weight of the clamp is minimal so it can be used on any record player with a fixed spindle.
Also many of the older manufactured records are warped. Some more, some less. This causes big problems for the diamond stylus of the cartridge to track the grooves properly. The stylus pressure fluctuates as the stylus moves up and down while trying to track the warps. With bad results: muddy sound reproduction with distortions and if the turntables drive isn’t really strong… audible flutter. In some cases the stylus may actually loose contact with the groove causing a hissing sound. Using the Tonar clamp will press the record onto the turntable platter, the problematical surface will be largely flattened now, while you play the record causing a dramatic improvement of the reproduced sound on old records.
