Vibration Is An Enemy Of Audio!
These are weights for audio uniquely designed by cheeTarh Consulting, and registered as Utility Model Regisitration at Patent Office. Most audio accessaries are categorized into electromagnetic compatibility and vibration containment. cheeTarh Audio Rack Weights (cheeTarh Gold Ingot) are the first ones for vibration containment. It is generally very important to reduce vibration in audio. In the case of speakers, if the speaker body itself vibrates, they cannot vibrate the air as intended. In the case of analogue vinyle record players or CD players, vibration is an enemy in order to acurately read out the recorded music information. What about other equipments, such as amplifiers, network audio players, etc.? In pure-audio, all electric circuit and wiring would generate microscopic levels of electricity by vibration, which becomes noise and negatively affects the sounds. Thus, it is very important to surpress vibration in all equipments for audio.
Various Audio Items To Control Vibration!
Many insulators of various matterials and shapes are marketed to contain vibration. Particularly, spike-shaped insulators block the up and down travel of vibration by extraporately minimizing the contact areas in-between. Also, weights are tried in various ways to control vaibration, as increase of mass by weights to surpress vibration which is a motion energy has a simple theory, and is easy to understand intuitionally. However, in most cases, weights are placed on audio equipments. Similarly, placing audio equipments on another equipment could be thought to be effective to contain vibration of one beneath. But, it must be reminded that there are certain conditions on which the feet and chassis of an audio equipment were designed by its manufacturer. Placing huge weights on an equipment might be out of the conditions, and the solidity or vibration containment capability that it originally had might not be performed.
About Specific Gravity Of Each Material!
The weights that cheeTarh Consulting developped, this time, was based on the idea of those that can increase the rack weights between feet of an audio equipment without touching it. There is a space of 25 cm width, 40 cm depth, and 1.5 cm height. The idea is to put a material with high specific gravity. The specific gravity of major materials are below.
Guangming red 8.9
Cast iron 7.2
Silicate stone 2.7
China clay 2.2
Coal stone 2.2
Pine resin 1.1
cheeTarh Gold Ingot Specification!
As you see, metals' specific gravities are outstandingly high, and materials such as granite that is commonly used for audio comes far short in terms of mass. Regarding woods, you could see that almost none is heavier than water. But, however high the specific gravity is, precious metals of cause cost too much. So, what cheeTarh Consulting chose is steel. Thus, steel plates. The corners of steel plate were rounded and it was shrink-wrapped twice, so that if it touches audio equipments any chance, it does not harm them. Since the shrink-film is slippery and cannot capture the vibration in the horizontal direction. non-slip resin is applied to the bottom of cheeTarh Gold Ingot, that would be integrated with the audio shelf, and suppress the vibration of the shelf. In addition, the steel plate is colored gold, the cheeTarh Consulting's brand color, for antirust. Please enjoy by placing them side-by-side, the bright gold like real gold bars. The length ratio is 1:2, so that you can easily adjust the weight and lay out them. For a normal full-sized equipment, 6 pieces (6.8Kg with CGI-1A) can be placed easily. Moreover, if the equipment is raised by insulators, 12 pieces (around 13Kg with CGI-1A), a two-tiered, can be placed. Depending on the equipment, space height differs, so there are two kinds of weights with different heights. For amplifiers, there are inlets for heat dissipation, and please do not block them. Since the bottom of the equipment has ledges, such as biss heads, please check the height carefully. Weights are usuful in many ways in life, such as for papers not to be flown by winds, so, even having some extra can be nice.

Lead Ingot, St. Name "Black Hole" Is Released, Too!
5.7Kg on your palm, this unusual heaviness is just like a mini black hole, which absorb everything. If you want to increase weight efficiently in a small space, for some reasons or another, this is recommended. Machinery cut lead chunk with cheeTarh Consulting logo label on fron of it, and taped bottom to avoid scratch and slip. The specific gravity is 11.4 which is 40% higher than steel, and fit to deadening of sub-woofer and speaker stands.
