CRS is a combinaton of a suspended stand and a traditional stand. CRS isolates the cymbal from the stand. This allows the cymbal to resonate freely without rattles. This also prevents vibration transfering to microphone stands that can cause direct buzzing noises in the mix and in-ear monitoring.
The advantages that CRS offers and why:
When you strike a cymbal, you transfer energy to it. Oscillations are thus created that cause the cymbal to make a sound. With a traditional stand, much of the cymbal’s energy is dissipated away in the stand. This can be felt if you place your hand on the stand after striking the cymbal. You will then feel strong vibrations, especially when large cymbals are used or playing swells using mallets. These vibrations can create undesired vibration/rattling noises in the cymbal stand. This could lead to problems if the vibrations reach their resonant frequency in the stand. When that happens, the stand will then go into free oscillation creating loud vibration noises. This problem is intensified if the stand is also located on a thin stage floor or a riser. The vibrations can also transfer to microphone stands and cause direct buzzing noises in the mix and in-ear monitoring.
The stands in use today have felt fittings to prevent vibration. This alone does not solve the problem. The bolt on which the cymbals rest is directly attached to the stand and therefore transmits much of the vibration to the stand. This is because the cymbals often hang at an angle and the cymbals rest directly on the bolt. The same problem also arises if the cymbals touch the bolt as they rock back and forth.
CRS has solved these problems by installing a bracket arrangement whereby the central bolt on which the cymbals rest is completely isolated from the rest of the bracket / stand by means of a rubber damper. This arrangement is placed directly under the cymbal. In this way, vibrations in all three axes are prevented from travelling further into the cymbal stand. This prevents undesirable rattling. In addition, the result will be an improved quality of the cymbal sound because less of the energy is dissipated away in the stand. A more open and natural sound in the cymbals will also be obtained, as they would now resonate more freely.
The rubber damper has a construction that makes it practically stable for movements in all three axes. This makes the ride / cymbals play no differently from the way they played using the cymbal stands of today.
CRS units are manufactured with a multi-bracket device which, with a simple grip, enables easy mounting on all cymbal stands.
